Record the Bearing Number
Keep the complete visible number, including prefixes, suffixes, spaces and symbols.
High-Speed Handpiece Bearing Solutions
Browse precision miniature bearings for dental turbine and high-speed handpiece applications. Search by bearing number, dimensions or handpiece model, then compare the complete product specification before ordering.
Selection Guide
Use a repeatable selection process rather than relying on one dimension, one visible marking or appearance alone.
Keep the complete visible number, including prefixes, suffixes, spaces and symbols.
Use unrounded measurements and record any flange or extended-ring dimensions separately.
Compare ball material, ring material, cage, shield, contact design and special geometry.
Record the brand, exact model and turbine or cartridge version where available.
Determine whether the requirement is for a front bearing, rear bearing or reviewed bearing set.
Distinguish a verified application from an exact number match, dimensional match or confirmation-required result.
Technical Comparison
Use this table as a comparison framework. The exact configuration must come from the reviewed product specification.
| Attribute | Common Options | What to Confirm |
|---|---|---|
| Ball Material | Ceramic / Steel | Exact product specification and intended application. |
| Contact Design | Radial / Deep Groove / Angular Contact | Product design and turbine application. |
| Cage | Phenolic / PAI / Polyamide / Other | Exact cage material and geometry for the SKU. |
| Shield / Seal | Open / Single Shield / Double Shield / Other | Complete configuration, not appearance alone. |
| Geometry | Standard / Flanged / Extended / Stepped | Physical dimensions and special ring features. |
| Position | Front / Rear / Bearing Set | Exact turbine or cartridge version. |
| Compatibility | Verified / Number Match / Dimensional Match / Confirmation Required | Evidence behind the application relationship. |
Compatibility Matters
A matching inner diameter, outer diameter and width identifies a dimensional candidate — not necessarily an interchangeable dental turbine bearing.

Handpiece Applications
Use brand hubs only where reviewed application data exists. Brand and model references identify possible applications; they do not imply affiliation or authorization.
Materials and Design
Ball material is one part of the complete product configuration. Compare the actual SKU, cage, shield, dimensions and application rather than selecting on ball material alone.

Contact design is an application-specific construction feature. Confirm the product design and turbine requirements rather than assuming external dimensions identify the contact geometry.
Technical Cross Reference
Search reviewed numbers, supplier references and alternative numbers without treating partial matches as confirmed interchangeability.
Review the brand, model, turbine or cartridge version and front or rear bearing position.
Use ID, OD, width and special geometry to narrow dimensional candidates before reviewing structure and application.
Quality and Inspection
Inspection can support identification and condition review, but it does not by itself confirm compatibility. Use the complete product specification and exact application data when selecting a replacement.
Record ID, OD, width and any flange or extended-ring geometry with suitable measuring equipment.
Noise, vibration and heat can indicate that inspection is needed; symptoms alone do not prove the root cause.
Keep the complete bearing number, packaging information and supplied documentation available when identification or traceability review is required.
Technical Resources
Review number, dimensions, materials, handpiece application and compatibility status.
Learn how to record ID, OD, width and special geometry without rounding away important differences.
Review noise, vibration, heat, contamination and premature failure as possible symptoms.
Review turbine versions, cartridge differences and bearing positions.
B2B Supply
Submit bearing numbers, current supplier references, dimensions, handpiece applications and forecast quantities for structured technical and commercial review.
Common Questions
Dental turbine bearings are miniature precision bearings used in high-speed dental handpiece turbine or cartridge assemblies. The correct product depends on the bearing specification and the exact application.
Start with the complete bearing number, exact handpiece model or measured ID, OD and width. Then compare materials, cage, shield, geometry, turbine version and bearing position.
Not necessarily. Bearings with the same ID, OD and width may still differ in ball material, cage, shield, contact geometry, lubrication, ring geometry or intended handpiece application.
The ball material is different, but ball material alone does not determine compatibility. Review the complete SKU specification and application requirements.
Use the handpiece model lookup and enter the brand, exact model and turbine or cartridge version where available. Confirm the front or rear bearing position before ordering.
Record the ID, OD, width and special geometry, then submit clear bearing and application photographs through the bearing identification page.
Start with the strongest information you have — bearing number, handpiece model or dimensions — then confirm the complete specification before requesting price.
