KaVo Dental Handpiece Bearings: Find by Model

Looking for a bearing for a KaVo handpiece? Record the complete handpiece model, separate turbine or head reference, and old bearing marking. Names such as 630B, 640C or MASTERtorque are starting points, not proof of fit.

Identify a KaVo Bearing by Model and Assembly

The labels below help you prepare a precise inquiry. This is not a model-to-bearing interchange chart: compare the exact handpiece, replaceable assembly and proposed item before ordering.

Model Identification Pages

Use the full marking to choose the relevant enquiry page. Grouped model names do not establish a shared bearing.

For these model markings, use the separate identification pages below. Keep all letters and suffixes with your enquiry; the links do not establish interchangeability.

25 series markings: KaVo 25 LPR GENTLEpower bearing identification | KaVo 25 LPA GENTLEpower bearing identification
625 markings: KaVo 625 bearing identification | KaVo 625CD bearing identification | KaVo 625CD PB bearing identification
634 Companion markings: KaVo 634 F4 Companion FG bearing identification | KaVo 634 P4 Companion PB bearing identification
636 markings: KaVo 636 / 636C FG bearing identification

More KaVo Model Identification Pages

Full handpiece marking: Copy every letter, number and suffix. If the label reads 630B, 640C, MASTERtorque, SMARTtorque, Gentle Silence or INTRAmatic, include the exact wording. These are inquiry clues, not evidence that a listed bearing fits.
Separate assembly reference: Photograph the turbine, cartridge or contra-angle head marking if present. State which assembly is being serviced; a handpiece family and a removable assembly may have different identifiers.
Removed bearing and position: Copy the complete old bearing code and note front or rear position if known. If markings are worn, photograph both faces and the surrounding assembly. Do not infer a new part number from the family name.
Proposed part evidence: Request the exact item’s code, drawing or specification and a direct fit reference for the specific assembly. Matching nominal dimensions can narrow candidates but cannot establish interchangeability alone.
Quote details: Include quantity and destination country, then request availability, written terms and documented fit scope for the proposed part.

Use the dental bearings guide, high-speed category or low-speed category to browse the wider range. Category membership alone does not confirm KaVo fit.

Verify the Proposed Bearing and Repair Scope

Identify the assembly: Copy the full handpiece name, suffix and any turbine, cartridge or contra-angle head reference. State whether the bearing came from a high-speed turbine or a low-speed/contra-angle assembly and record front or rear position if known. A KaVo family name alone cannot establish a part match.
Check the exact proposed item: Ask for its part code and item-specific drawing or specification. Compare documented dimensions, closure, ring and ball materials, cage, tolerance and lubrication with the applicable service information. Equal nominal size or a similar photo does not prove interchangeability.
Inspect symptoms and processing: Noise, heat and run-out can have causes beyond the bearing. Have the assembly inspected and follow the exact device’s service and reprocessing instructions. Do not infer sterilization suitability or service life from a generic material description.

KaVo names identify handpieces for a part review; they do not state that KaVo manufactured or endorsed an offered replacement bearing.

KaVo Handpiece Bearing FAQ

Which bearing fits a KaVo 630B or 640C handpiece?

Neither family label alone confirms a bearing. Send the full handpiece designation, turbine or cartridge reference, old bearing marking and bearing position. Ask for a direct fit reference and specification for the exact proposed item before ordering.

Are KaVo 630B and 640C bearings interchangeable?

Do not assume interchangeability from the model family, an old catalog code or equal nominal dimensions. Compare the exact assemblies and removed bearings, then verify an item-specific drawing and direct fit evidence for each model.

Should I choose ceramic or steel bearings for a KaVo turbine?

The material alone does not determine suitability. Compare the exact assembly service requirements with the proposed bearing documented construction, cage, closure, tolerance, lubrication and operating conditions. Request the item specification before choosing.

Will a bearing change fix noise in a KaVo Gentle Silence handpiece?

Noise can come from the bearing, spindle, chuck, air supply or other parts of the assembly. Inspect the complete instrument under the applicable service instructions, identify the failed component, and then confirm the exact replacement reference.

Can a repair shop request a bulk KaVo bearing quote?

Yes, send the exact model and assembly references, proposed part code if known, quantity and delivery country through the contact form. Request item specifications, documented fit scope, availability and written quote terms. This page does not promise a universal discount or lead time.
