Identify an NSK Handpiece Bearing by Model and Old Code
“NSK air turbine bearing” is not one part number. NSK uses some family names across different instrument types, so first distinguish an air turbine cartridge from a motor-driven contra-angle head. Then record the complete device and assembly code before reviewing a loose bearing.
NSK device names: air turbine or contra-angle?
| NSK instrument type | Examples on NSK product listings | Record for part review |
|---|---|---|
| Air turbine | Ti-Max Z900 / Z800 | Full Z model, coupling and cartridge reference |
| Air turbine | S-Max M series, including M900 / M800 | Full M model and cartridge reference |
| Air turbine | Pana-Max PLUS / Pana-Max2 | Exact series and cartridge reference |
| Contra-angle | Ti-Max Z95L / Ti-Max X95L | Full model and head/gear assembly |
| Contra-angle | FX series, including FX25m | Full model and head/gear assembly |
Device-name sources: NSK’s air turbine catalogue and contra-angle catalogue. These examples identify NSK instruments only. They are not this site’s inventory, a bearing cross-reference or evidence that a proposed part fits a device; regional and older models can differ.
For a loose bearing, also send its original marking, front or rear position and measured bore, outside diameter and width. Our bearing size measurement guide explains how to record those dimensions without treating a nominal size as proof of compatibility. Use the checklist below to prepare the inquiry.
- Full instrument model: Copy every character and suffix from the device label. Distinguish an NSK air turbine from a contra-angle before selecting an assembly. The current NSK examples above are identification clues; an older or regional label should be checked against its own documentation.
- Assembly and position: Include the turbine, cartridge or rotor reference and state whether the removed bearing is at the front or rear if known. Different assembly versions and positions need separate checks.
- Old bearing marking: Photograph both faces and copy the complete code exactly as found. A code from a generic list cannot establish that a bearing fits a named NSK model; confirm the specific cartridge or head assembly and bearing position.
- Drawing and dimensions: Add a drawing or measured inner diameter, outer diameter and width, noting their source. Compare a candidate’s closure, materials and cage only from its exact specification.
- Quote details: State quantity and delivery country, then request the precise proposed part code, documented fit scope, availability and current quotation terms.
Use the dental bearing guide or browse high-speed and low-speed categories while narrowing the part. These category routes do not confirm NSK compatibility.
Verify the Proposed Bearing for an NSK Handpiece
- Exact model and assembly: Compare the complete handpiece model, turbine or cartridge reference, and front or rear bearing position with the relevant service documentation. A series name does not establish a replacement.
- Exact part specification: Request the proposed bearing code and drawing. Compare dimensions, closure, ring and ball materials, cage, tolerance and lubrication where documented. A nominal size or photograph alone does not prove fit.
- System and reprocessing: If the handpiece documentation mentions Clean Head or a specific processing method, follow that exact model’s instructions. A bearing shield or material label by itself does not establish system performance, sterilization suitability or service life.
NSK names here identify handpieces for a part review; they do not state that NSK manufactured or endorsed an offered replacement bearing.

NSK Handpiece Bearing FAQ
Can I replace only the bearings in an NSK turbine cartridge?
The answer depends on the exact cartridge and the manufacturer’s service instructions. Identify the assembly and inspect the rotor, shaft, housing and bearing seats before deciding on a repair. A bearing code or nominal size alone does not establish that a cartridge can be rebuilt or that a replacement fits.
Do these bearings fit Ti-Max Z handpieces?
A Ti-Max Z series name alone cannot confirm fit. Provide the complete model and suffix, turbine or cartridge reference, old bearing marking and bearing position. Request an exact-part specification and a direct model-specific fit reference before ordering.
Can you identify a bearing for an NSK Phatelus handpiece?
Send the complete Phatelus handpiece model, assembly reference and marking on the removed bearing. If the marking is unreadable, attach a clear photo and any drawing or measured dimensions. Availability and fit remain unconfirmed until the exact item is reviewed.
How long does an NSK handpiece bearing last?
There is no reliable universal interval for a replacement bearing. Noise, vibration, run-out or lower performance may have several causes. Follow the handpiece manufacturer’s service and reprocessing instructions and inspect the assembly before selecting a part. Do not infer service life from ball material alone.
