Need a replacement bearing for a KaVo 659B PB handpiece? Send the full handpiece label and the old bearing or turbine code so the exact item can be reviewed before a quote.
Keep the complete 659B PB handpiece reference with your inquiry. A handpiece model name is not a manufacturer bearing part number. Record the original turbine or cartridge reference and the location of the bearing you need before comparing a proposed replacement.
Photograph any legible markings on the removed bearing and the assembly label. Include both sides of the part and its mounting position when available. If a marking is unreadable, send the drawing or measured sample details rather than choosing a part from a similar product photograph.
| Item to identify | Information to provide or confirm |
|---|---|
| Handpiece and assembly | Complete 659B PB label, suffix and turbine or cartridge reference. |
| Bearing position | Identify the location in the original assembly and whether you need a loose bearing or a complete assembly. |
| Code and geometry | Old bearing code; bore, outside diameter, width and flange or shield details from the applicable drawing or measured sample. |
| Proposed replacement | Request its own item code, specification and documented fit scope. |
| Materials and operating limits | Confirm these against documents for the exact proposed part. A ceramic label or generic bearing series does not establish speed, life or reprocessing suitability. |
| Order details | Quantity, destination, sample needs and any drawing, material or inspection documents required. |
This page does not establish interchangeability with other KaVo models or NSK handpieces. Similar dimensions, a shared model number or appearance alone do not confirm fit. Ask for evidence that links the exact proposed bearing to the exact handpiece and assembly reference before ordering.
The handpiece’s push-button reference should not be treated as a feature that makes a loose bearing easier to install or remove. Use the original manufacturer’s service instructions and qualified repair personnel for the relevant assembly.
Use the inquiry form on this page or send your model and old-part details. Include the full handpiece and assembly references, old bearing code or drawing, quantity and destination. If the form has no upload field, email the photos after your inquiry.
Confirm the proposed item, fit scope, available documents, warranty terms and current shipping options in writing before ordering. You can also browse the KaVo bearing guide to locate other model references; those links do not establish compatibility.
Our FAQ section covers common questions about our dental bearings, including types, materials, quality control, customization, and global shipping to help you make informed decisions.
Provide the exact handpiece model and existing bearing code for a model-specific review.
Ask whether a material specification is available for the exact bearing code.
Compare the applicable product documents for the exact items, if available; confirm the intended handpiece model separately.
Ask whether model-specific service-life evidence is available. A general interval may not apply to an individual item.
Ask for current documents identifying the responsible entity, scope and applicable product before relying on a compliance statement.
Ask whether test results are available for the exact bearing model before relying on a performance value.
For a specific bearing, request the applicable drawing, material and tolerance information, inspection criteria, and any available test report. Share the handpiece model and bearing code so the documents can be matched to the exact part. Test coverage and acceptance limits vary by item.
Lead time depends on the exact part number, quantity, and stock or production status. Include your destination and required date in the RFQ and request a written lead-time confirmation for that order.
For a nonstandard bearing, send a drawing or sample, the required dimensions and tolerances, estimated quantity, and application details. Feasibility, material options, minimum order quantity, and documentation must be confirmed for the specific request.
Follow the handpiece manufacturer’s instructions for cleaning, lubrication, sterilization, and service intervals. Maintenance requirements can vary by handpiece and bearing assembly; use the applicable IFU for your exact model.
For volume pricing, specify the exact bearing code or drawing, estimated order quantity, and delivery schedule. Request a quotation with the applicable quantity breaks and terms.
Include the destination country and quantity in your inquiry. Available shipping methods, cost, import responsibilities, and delivery time should be confirmed in the quotation.
For bearing inquiries, provide the exact model or existing bearing code. Request the applicable specification and supporting documents before ordering.
Start with the exact handpiece brand and model, and record the code printed on the removed bearing if it is legible. A model name alone may cover several turbine or cartridge revisions, so include photos of the original part and its mounting position when available.
Compare the proposed bearing with the original drawing or measured sample: bore, outside diameter, width, flange geometry, shields, cage, and any markings. Material, lubrication, and sterilization requirements need part-specific confirmation; do not infer them from a similar-looking model or product photo.
For an accurate quotation, send the bearing code or handpiece model, photos or a drawing, required quantity, destination country, and the application or repair issue. If you need a complete turbine, cartridge, or rotor rather than a loose bearing, state that clearly in the inquiry.
Before ordering, request the specification and available inspection or test documents for the exact part number. Confirm sample availability, lead time, shipping terms, and any compatibility statement in writing. Send your part details for review and a quotation.
