For a Lares 330E or 557 parts enquiry, identify the exact instrument and the component you want reviewed. Keep the two model markings separate and send the removed part code or clear photographs before comparing a candidate.
State whether the instrument label reads 330E or 557 and include every visible suffix or assembly reference. Add a photograph of the instrument label and the removed component in context. Do not use a part description for one model as evidence for the other.
If you need a rebuild kit, provide its item code or list the components required. For a loose bearing, rotor or complete assembly request, state that supply scope explicitly. A model name does not define the contents of a kit or confirm the source of its components.
Use the form on this page for a Lares 330E / 557 part review. Include:
Use the existing Email link or Contact page when sending photographs or drawings. Describe an unreadable marking as unknown instead of filling it from a similar-looking part.
Compare the proposed item code, drawing revision and construction with the original component and its service information. Material, tolerance, closure and assembly requirements need part-specific confirmation. Matching a nominal dimension is one screening step, not proof of interchangeability.
Continue with the Lares handpiece part-identification guide, or send a part enquiry with the full model and existing part details.
Request the candidate item code, applicable specification and written supply scope before ordering. Brand names identify the instrument or enquiry reference and do not state OEM manufacture, approval or affiliation.
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.
