31029-2202080 Center Bearing Part Number, Dimensions, and Fitment Guide

The part number 31029-2202080 identifies the center bearing you are researching, but the number alone is not enough to confirm its dimensions or vehicle fitment. Before ordering, compare the original part number with the vehicle or axle application and verify the bearing’s measured dimensions, mounting arrangement, and support configuration. Shengfan can help B2B buyers review these details before an inquiry or order, subject to the product information available for confirmation.

Key Takeaways

• Treat 31029-2202080 as an identification reference, not standalone proof of fitment.
• Confirm the vehicle or axle details and compare the old part or technical drawing against the replacement.
• Record three essential measurements in millimeters: bearing inner diameter, support width, and mounting-hole center spacing.
• Do not assume 31029-2202076 is interchangeable with 31029-2202080 without a verified cross-reference.
• Ask suppliers to confirm the supplied part number, configuration, packaging, MOQ, and lead time in writing.

Who This Guide Is For

This guide is intended for automotive parts distributors, axle and driveline buyers, repair networks, and importers evaluating a 31029-2202080 center bearing. It is also useful for procurement teams checking an existing part against a new supplier’s offer. If you are sourcing for aftermarket replacement, fleet maintenance, or inventory planning, the same verification steps can help reduce part-number and fitment mismatches.

What a Center Bearing Does

A center bearing, also called a drive shaft center support bearing, supports the propeller shaft where the shaft assembly requires an intermediate support point. The bearing works with its support or bracket to hold the shaft in position while allowing it to rotate. Its rubber or elastomer support, where used in the design, can help isolate vibration between the rotating shaft and vehicle structure.

Exact construction depends on the application. A replacement may differ in bearing dimensions, support shape, rubber compound, bracket design, or other configuration details, even when two parts appear similar. For this reason, visual resemblance is a useful preliminary check but should not replace part-number and dimensional verification.

Part Number, Dimensions, and Fitment

How to Verify the Part Number

Start by reading the number on the original component, packaging, or parts documentation. Confirm whether the reference is exactly 31029-2202080, including every digit and separator, and note any additional markings or manufacturer references. If the original label is missing or unreadable, use the vehicle or axle identification details and measurements to support the lookup rather than selecting a part based only on appearance.

The related number 31029-2202076 may appear during a search or supplier discussion, but a similar number does not establish interchangeability. Ask for documented cross-reference information that matches the relevant vehicle or axle application and product configuration. If confirmation is unavailable, treat the numbers as separate references until the supplier or applicable parts documentation verifies otherwise.

Which Dimensions to Measure

No verified dimensional specification for 31029-2202080 is provided in the information available for this guide, so we do not publish an unconfirmed size as a product fact. Instead, compare the actual part or a reliable drawing against the replacement offer. Record these three measurements in millimeters: the bearing inner diameter, the support’s overall width, and the center-to-center spacing of the mounting holes.

Depending on the design, you may also need to record the outer diameter, bracket height, mounting-slot dimensions, and the position of the bearing relative to the support. Use the same measurement points for the original and replacement, and state whether each measurement comes from a physical part or a drawing. If you use a measuring tool that displays increments such as 0.1 mm, include the displayed precision in your notes rather than rounding measurements inconsistently.

Fitment Matching Framework

1. Identify the application. Provide the vehicle make, model, model year, engine or drivetrain details where relevant, and axle or driveline information. Include a VIN or chassis reference when appropriate and when you are authorized to share it.
2. Confirm the reference number. Compare 31029-2202080 with the marking on the removed part and the available parts documentation. Record other numbers separately instead of treating them as confirmed equivalents.
3. Compare physical specifications. Check the three core measurements in the table, then review additional mounting and support details that affect installation. A dimensional match should be assessed together with the complete support configuration.
4. Review the installation arrangement. Check the bracket orientation, mounting points, and bearing position against the vehicle’s existing setup or a reliable drawing. If the assembly differs, request clarification before approving the order.
5. Obtain written confirmation. Ask the supplier to identify the part number and application being quoted and to state which drawing, sample, or reference supports the match. Keep that confirmation with the purchase documentation.

Materials and Configuration Considerations

Center support assemblies can use different bearing and support configurations, and material choices may vary by product design. For the 31029-2202080 reference, do not assume a particular bearing type, rubber compound, bracket material, or internal specification unless the supplier confirms it. Request a drawing, product specification, or clear product photographs when those details affect your application.

For buyers replacing an existing part, compare not only the bearing but also the full support assembly supplied. Confirm whether the quoted item includes the bracket or other components needed for the intended replacement. This prevents confusion between a bearing-only offer and a complete center support assembly.

Pricing, MOQ, and Lead Time

Price and availability can depend on order quantity, packaging requirements, destination, and whether the requested specification is an existing supply item or requires further evaluation. MOQ and lead time should therefore be confirmed in a current quotation rather than inferred from the part number. Ask whether the quotation covers the complete assembly, the stated quantity, and the packaging needed for your sales channel.

For an efficient quotation, send the part number, target quantity, delivery country, application details, and any drawing or reference photographs. If you require a label, private packaging, or a particular document set, include those requirements before the quote is finalized. Shengfan can review the inquiry details and advise what additional information is needed to confirm supply; availability and terms remain subject to order review.

Supplier Evaluation Checklist

• Can the supplier confirm the exact reference 31029-2202080 and describe the item being quoted?
• Can they provide a drawing, dimensional details, or another basis for fitment verification?
• Have they distinguished confirmed cross-references from numbers that merely look similar?
• Is it clear whether the offer is for a bearing alone or a complete support assembly?
• Are MOQ, lead time, packaging, and quotation validity stated for your requested order?
• Is there a clear process for checking a sample or resolving a specification question before bulk purchasing?

Conclusion: Confirm Before You Order

The safest way to source a 31029-2202080 center bearing is to verify the part number, application, and physical configuration together. The number is a starting point, not a substitute for checking inner diameter, support width, mounting-hole spacing, and the relevant vehicle or axle details. Do not treat 31029-2202076 as interchangeable unless a reliable cross-reference confirms it for your specific application.

For your next step, prepare the exact part number, application details, three core measurements in millimeters, and photographs or a drawing if available. Send these details to Shengfan for a product and quotation review, and request written confirmation of the quoted configuration, MOQ, and lead time before placing an order. This gives your purchasing team a clearer basis for fitment approval and sourcing decisions.
