Motion & bearings
Bearings, ball screws and linear motion. Discuss dimensional consistency, load, wear and the finish required for your assembly.
Discuss motion & bearingsPRECISION BALLS · EXPERTISE SINCE 1980
Precision balls.
Specified for
your application.
Source by material, diameter, grade and finish. Bring an existing specification or describe the job, and our team will help work through the requirements.
START WITH THE APPLICATION
What does the ball need to do?
Choose the function closest to your project. We’ll carry it into your enquiry so you can start with the application.
Sealing & flow control
Check valves, pumps and metering. Review the ball, seat, operating fluid and corrosion requirements together.
Discuss sealing & flow control
Locking & retention
Quick connects, swivels, detents and couplings. Start with the fit, working conditions and retention requirements.
Discuss locking & retention
Custom engineering
Metrology, instruments, electronics and specialty assemblies. Share your drawing, part reference or functional requirement.
Discuss custom engineeringApplication illustrations show typical functions, not specific supplied assemblies.
For projects in energy, food, chemical processing and other demanding environments, share the operating and product-contact requirements.
Precision is more
than a diameter.
A nominal size alone does not define the complete requirement. Specify the standard, grade and characteristics your application needs.
Nominal diameter
The stated size, in metric or inch units. A micrometer illustrates checking the diameter against the required limit.
Spherical form
How closely the ball follows the required spherical shape. The inspection setup illustrates checking form around the ball.
Lot diameter variation
The permitted diameter difference between balls within a defined lot. Inspection compares measurements; the difference may not be visible to the eye.
Surface finish
The texture or roughness of the surface. A surface inspection setup illustrates the measurement context; appearance alone does not establish the finish.
AI-generated measurement illustrations. These scenes explain inspection methods and do not show actual inspection results.
Not sure which grade? Ask our teamMATERIALS & SELECTION
Compare the material.
Confirm the specification.
Consider the environment, working conditions and required properties. Exact material, grade, size and availability are confirmed with the quotation.
STEEL
Carbon steel balls
Low- and high-carbon options, with a range of hardnesses, for bearings, mechanical components, finishing and general industrial uses. Corrosion resistance is a selection consideration.
STEEL
Chrome steel balls
High hardness and wear resistance for bearings, ball screws, swivels and drilling. Ask about AISI 52100-type applications and the required precision grade.
STEEL
Stainless steel balls
Discuss corrosion resistance, hardness, magnetic behavior, finish and any passivation requirements.
Explore stainless steel options
302, 304, 304L, 316, 316L, 420HC, 430, 440C, 904L and Nitronic 50 options. Discuss annealed, non-annealed and passivated requirements.
GLASS
Glass balls
Soda-lime, borosilicate, valve-grade, clear and colored balls for flow control, optics, electronics, spacers and engineering applications.
CARBIDE
Tungsten carbide balls
High density and hardness for wear, impact, metrology and specialized high-load applications. Ask about the required precision grade.
CERAMIC
Zirconium oxide balls
Smooth, wear-resistant ceramic balls for chemical resistance, electrical insulation and applications where low metallic contamination matters. Industrial and pharmaceutical options.
Need another material?
Ask about ceramics, engineering polymers, specialty alloys and precious metals. Share the composition and properties your project needs.
CONFIRM BEFORE ORDERING
Put the requirements
on the record.
Tell us what must be verified for your application. Our team can review the required specification and discuss available documentation with the quotation.
Documentation and compliance requirements should be agreed for the particular material and order.
Discuss my specification- Drawing, standard & grade
- Part number or drawing revision, required ABMA, ISO or application-specific criteria, nominal diameter and tolerance.
- Material & condition
- Composition, hardness, finish, passivation, magnetic behavior and operating environment.
- Inspection & documentation
- Requested inspection results, material certificates, traceability, product-contact or sourcing requirements.
- Quantity & repeat supply
- Sample or production quantity, packaging, delivery schedule and recurring order needs.
If we do not have it,
we can get it.
Bring us an unusual material, a nonstandard diameter or a hard-to-find replacement. We’ll help identify a practical sourcing path.
Before you specify.
Start with what you know. We’ll help clarify the remaining details.
What if I don’t know the material or grade?
Describe the function, operating environment and result you need. Add an existing part number or drawing reference if available. You can contact us before completing the technical specification.
Can I request metric or inch sizes?
Share the nominal diameter and units, along with the tolerance or grade if known. Availability depends on the material, size, precision and quantity.
Can I request inspection or traceability documents?
Include the specific documents, inspection requirements and traceability needs with your enquiry so they can be reviewed and confirmed for the order.
What about product contact or unusual environments?
Describe the intended contact, chemicals, temperature, cleaning process and documentation needs. Suitability and offered options must be reviewed for your application.
