Dental Handpiece Bearings by Brand

Start with the brand marked on your dental handpiece. Then record the complete handpiece model, any turbine or cartridge reference, and the code on the bearing being replaced. A brand or series name helps you find a relevant page, but it does not identify one interchangeable bearing.

What to Record Before Comparing Bearings

1. Copy the full handpiece model, including suffixes and revision marks.
2. Record the turbine or cartridge reference separately if the assembly has one.
3. Copy every character of the removed bearing code. Note its front or rear position if known.
4. If the marking is unclear, photograph both sides of the bearing and the handpiece or assembly label. Include a drawing or measured inner diameter, outer diameter and width if available.

These details narrow the search. A matching photograph or nominal size alone cannot confirm material, cage, closure, tolerance or fit in the assembly.

How to Check a Proposed Replacement

Ask for the specification of the exact proposed bearing code. Compare its dimensions and construction with the removed part and applicable handpiece service information. For a model fit claim, request a direct reference naming both the bearing code and the complete handpiece or assembly version. If that reference is unavailable, leave the fit question open rather than treating a broad brand match as proof.

Need Help Identifying a Part?

Send the model, assembly reference, old bearing code, position and required quantity through the contact page. If you have photographs or a drawing, include them by email when the form cannot accept files. The review can then focus on a specific candidate and its available documentation.
