PROCUREMENT GUIDE
Titanium Ball & Sphere Buying Essentials
Precision Requirements Must Be Defined by Measurable Parameters
Terms such as “precision,” “high grade” or “G-grade” are not sufficient by themselves for titanium balls. Final acceptance should define the required diameter tolerance, diameter variation, roundness or deviation from spherical form, lot variation, surface finish and agreed inspection method.
Titanium ball and sphere sourcing starts with the product form, titanium grade, diameter or geometry, dimensional tolerance, roundness, surface finish, custom features and inspection requirements. Define these parameters before quotation so the manufacturing and measurement plan can be reviewed for the actual component.
Ball or Sphere Form
Start by defining whether the requirement is a solid precision ball, hollow sphere, float, hemisphere or drawing-based spherical component, because each form requires a different manufacturing and inspection approach.
Specify the titanium grade, UNS designation and applicable raw-material or project specification according to the required form, service environment and mechanical requirements.
Review: Grade · UNS · Material Specification · Condition · Heat / Lot Traceability
Typical Grades: Grade 2 · Grade 5 · Grade 7 · Grade 12 · Other Grades by Review*
Geometry, Tolerance & Surface
Define nominal diameter, dimensional tolerance, roundness or spherical-form requirements, surface finish and any drawing-based features using measurable acceptance criteria.
Solid Ball Review: Diameter · Diameter Tolerance · Roundness · Lot Variation · Ra
Custom Component Review: Hole · Thread · Port · Slot · Datum · GD&T
Inspection & Documentation
Define the measurement method, sampling scope, material traceability and required inspection records according to the geometry, tolerance level and purchase specification.
*Where a customer specifies G-grade terminology, HELE reviews the underlying dimensional and surface requirements individually against the applicable drawing or purchase specification. ISO 3290-1 itself is scoped to finished steel balls for rolling bearings.

Different Sphere Forms Require Different Specifications
Solid precision balls are controlled primarily by diameter, roundness and surface requirements; hollow spheres and floats require wall, seam or weld and functional-test specifications; valve-ball and modified components require drawing-defined ports, interfaces, datums and geometry. These product forms should not share one universal tolerance or inspection specification.
*Leak, pressure, buoyancy, coating and other functional tests are reviewed according to the product design, application and agreed purchase specification.
SELECTION GUIDE
How to Select the Right Titanium Ball or Sphere
Select titanium balls and spheres by product form, material grade, geometry, dimensional tolerance, roundness, surface finish, application conditions and inspection requirements. Solid, hollow and drawing-based spherical components should be specified using form-specific engineering parameters rather than one universal precision grade.
1
Choose the Product Form
Start by defining whether the requirement is a solid precision ball, hollow sphere, float, hemisphere, valve-ball component or other drawing-based spherical part.
Why It Matters: The selected form determines the manufacturing route, critical dimensions and inspection method.
2
Select Grade & Material Requirements
Specify the titanium grade, UNS designation, material condition and applicable material or project specification according to the service environment, mechanical requirements and component form.
Review: Grade · UNS · Condition · Material Specification · Heat / Lot Traceability
3
Define Geometry & Dimensions
Define the nominal diameter and all form-specific geometry, including wall thickness, holes, threads, ports, slots, flats, connection features and drawing datums where applicable.
Solid Ball: Diameter · Hole / Thread · Modified Features
Valve / Custom: Port · Slot · Stem Interface · Datum · GD&T
4
Define Precision & Surface Requirements
Specify dimensional tolerance, diameter variation, roundness or deviation from spherical form, lot variation and surface roughness using measurable acceptance criteria.
Provide the intended application and relevant service conditions so form-specific functional requirements can be reviewed together with the geometry and material selection.
Define the measurement method, sampling plan, traceability and required records according to the specified geometry, tolerance, surface and functional requirements.
Documentation: MTC · Heat / Lot Traceability · Dimensional Report · Inspection Record · CoC*
When Applicable: Functional Test Report · Leak / Pressure / Buoyancy Record*
Do Not Specify “Precision Grade” Alone
Terms such as G10, G25 or “high precision” do not fully define a titanium-ball requirement. The purchase specification should identify the required diameter tolerance, diameter variation, roundness or spherical-form deviation, lot variation, surface finish and agreed inspection method.
About G-Grade Terminology
If a customer uses G-grade terminology, HELE reviews the underlying dimensional and surface requirements individually against the drawing or purchase specification. ISO 3290-1 itself is scoped to finished steel balls for rolling bearings and should not be treated as blanket finished-product compliance for titanium balls.
Need help selecting the right titanium ball or sphere for your project?

Documentation: MTC · Dimensional Report · Inspection Record · Functional Test Report* · CoC*
Packing: Lot Identification · Surface Protection · Part Separation · Export Packing
Inspection & Measurement Note:
Measurement Capability Must Match the Required Tolerance: As dimensional requirements become tighter, the measurement method, equipment resolution, calibration status, sampling plan and measurement uncertainty should be appropriate for the specified tolerance and roundness requirement.
Inspection Requirements Depend on Product Form: Solid precision balls, hollow spheres, floats and valve-ball components require different inspection plans. Final measurement methods, sampling scope, functional tests and acceptance criteria are confirmed against the drawing, purchase order and agreed inspection requirements.

Specialty & Qualification-Controlled Grades
Grade 9 · Grade 23 · Customer-Specified Grades
Specialty titanium grades can be reviewed for drawing-based projects where the material specification, component geometry, manufacturing route, inspection plan and end-use qualification requirements are clearly defined.
Review: Material Specification · Form · Geometry · Inspection · Qualification Requirements
Important: Material-grade compliance does not by itself establish medical, aerospace or other finished-component approval.
Material Specification and Finished-Ball Precision Are Separate Requirements
The titanium grade defines the material requirement, while diameter tolerance, roundness, spherical-form deviation, surface roughness, custom geometry and inspection method define the finished component. A material certificate alone does not establish the dimensional or functional performance of the finished ball or sphere.
Availability Note:
Not every titanium grade is available in every solid-ball, hollow-sphere, float or custom-machined configuration. Final Grade × Form × Diameter × Tolerance × Surface × Quantity capability is confirmed during quotation review.

FREQUENTLY ASKED QUESTIONS
Titanium Ball & Sphere FAQs
Find answers to common questions about titanium ball and sphere forms, precision requirements, G-grade terminology, bearing and valve applications, hollow spheres, inspection and quotation requirements.
What is the difference between a solid titanium ball and a hollow titanium sphere?
A solid titanium ball is manufactured from solid material and is typically specified by diameter, dimensional tolerance, roundness, surface finish and any custom-machined features. A hollow titanium sphere is defined by outside diameter, wall thickness, hemisphere or seam construction, joining method and, where required, leak, pressure or buoyancy testing. The two forms should not share one universal tolerance or inspection specification.
How should precision be specified for a titanium ball?
Precision should be defined using measurable parameters such as nominal diameter, diameter tolerance, diameter variation, roundness or deviation from spherical form, lot diameter variation, surface roughness and visual surface limits. The required measurement method and sampling plan should also be agreed when tolerances are critical.
Can G10, G25 or ISO 3290 be directly applied to titanium balls?
Not as blanket finished-product compliance. ISO 3290-1 is scoped to finished steel balls for rolling bearings. If a customer specifies G10, G25 or another G-grade term for a titanium ball, HELE reviews the underlying diameter variation, spherical-form deviation, lot variation and surface requirements individually against the drawing or purchase specification.
Does HELE supply titanium ball bearings?
HELE supplies titanium balls that can be reviewed for bearing-related applications where the customer defines the required diameter, roundness, surface finish, load, wear and assembly conditions. This page does not represent complete titanium bearing assemblies unless specifically stated. Suitability for a complete bearing system requires application- and assembly-level qualification.
Does HELE manufacture titanium ball valves?
This page covers titanium valve-ball components rather than complete ball valves. Drawing-based valve-ball components can be reviewed with ports, slots, stem or trunnion interfaces, spherical contact surfaces, coatings and dimensional requirements defined by the valve OEM drawing. Complete valve sealing and leakage performance depend on the ball, seat, stem, body, gasket, assembly and actual service conditions.
What information is required for a hollow titanium sphere or float?
For hollow spheres and floats, provide the titanium grade, outside diameter, wall thickness, sphere or hemisphere construction, seam or joining requirement, quantity and surface condition. For functional applications, also provide the service medium, temperature, pressure, connection geometry and any leak, pressure, buoyancy or density-test requirements.
What inspection and documentation can be supplied?
Depending on the product form and purchase requirements, inspection can cover diameter, roundness, surface condition, custom-machined geometry, wall thickness and other drawing-defined characteristics. Documentation can include the MTC, heat or lot traceability, dimensional inspection records and agreed functional-test reports where applicable. Measurement method, sampling scope and report format should be confirmed during quotation when tight tolerances or functional testing are required.
What information should I provide for a titanium ball or sphere quote?
Please provide the product form, titanium grade or UNS, diameter or key geometry, quantity, application and delivery destination. For solid precision balls, include dimensional tolerance, roundness and surface requirements. For hollow spheres or floats, include wall thickness and functional-test requirements. For valve-ball or modified components, provide the drawing with ports, holes, threads, interfaces, datums and GD&T where applicable. Uploading a drawing or purchase specification is recommended for custom and precision components.
