Specifications

⚠️ Fitment Notice: Always verify OEM part number A0149812105 against your vehicle VIN and axle specification before ordering. Wheel suspension bearing fitment on heavy trucks is safety-critical — incorrect selection may result in bearing failure and loss of vehicle control.

Design & Construction

The A0149812105 is a single-row tapered roller bearing with a 65mm bore and 152mm outer diameter, engineered as a direct OEM replacement for Mercedes-Benz heavy truck wheel suspension assemblies. At 4.56 kg, this is a substantial heavy-duty bearing designed to sustain extreme combined radial and axial loads.

• Tapered roller geometry provides superior combined radial and axial load capacity — essential for heavy truck wheel suspension under full GVW loading

• 65mm bore / 152mm OD — large OD-to-bore ratio, characteristic of heavy truck axle wheel suspension positions requiring high load density

• 48mm width — wider than standard metric series, delivering increased roller length and higher dynamic load capacity

• Cone and cup assembly — separable design allows individual cone or cup replacement in the field, reducing maintenance downtime

• Line contact between tapered rollers and raceways delivers high load capacity and long service life under heavy-duty, high-impact conditions

• Open design — field-lubricated with NLGI 2/3 wheel bearing grease per OEM specification

• GCr15 / AISI 52100 through-hardened steel — 60–64 HRC, full material traceability available

Applications

Cross Reference

For confirmed FAG / SKF / Timken cross-reference numbers, please contact us with your vehicle model, axle type, and VIN. We will provide a verified dimensional cross-reference before shipment. The 65×152×48mm dimension set is a heavy-series non-standard configuration, typical of Mercedes-Benz proprietary wheel suspension bearing specifications.

Dimensional & Weight Data

The 4.56 kg weight and 152mm outer diameter confirm this bearing's heavy-duty commercial vehicle classification. The large OD-to-bore ratio (152mm OD vs 65mm bore) combined with the 48mm width provides a large roller complement and extended contact length, resulting in high dynamic and static load ratings well-suited for Mercedes-Benz heavy commercial vehicle axle duty.

FAQ

Q: What Mercedes-Benz vehicles use the A0149812105 bearing?

A0149812105 is a Mercedes-Benz OEM part number used on heavy truck wheel suspension assemblies, including Actros, Axor, Atego, and Arocs series. Always verify against your VIN and axle specification before ordering.

Q: What is the FAG / SKF / Timken equivalent part number?

Please contact us with your vehicle model and VIN for a confirmed cross-reference. We will verify the dimensional equivalent (65×152×48mm) against FAG, SKF, Timken, and other major brand catalogues before supply.

Q: How does this bearing compare to other Nexans Mercedes-Benz truck bearings?

Q: What precision grade should I specify?

P0 (standard) covers the majority of heavy truck aftermarket replacement applications. P6 or P5 is available for OEM supply or applications requiring tighter running accuracy.

Q: What lubrication is recommended?

Heavy truck wheel suspension bearings of this type are typically lubricated with NLGI Grade 2 or Grade 3 lithium complex or calcium sulfonate wheel bearing grease per OEM specification. Follow your vehicle OEM's regreasing intervals.

Q: What is the correct installation procedure?

For a bearing with 65mm bore and 4.56 kg weight, use a hydraulic press or induction heater for installation — never strike the bearing directly. Set preload or end-play strictly per the OEM workshop manual. Tapered roller bearing preload adjustment is safety-critical on wheel suspension positions.

Q: Is OEM / private-label packaging available?

Yes. Custom box printing (your brand / part number), laser-engraved part number (A0149812105) and logo on the bearing ring, and full inner/outer branded packaging are all available. All IP rights remain yours. MOQ and pricing on request.

Q: What documentation is available?

GCr15 / AISI 52100 material certificates, dimensional inspection reports, hardness test reports (60–64 HRC), packing lists, commercial invoices, certificates of origin. SGS / BV / TÜV third-party inspection supported on request.

Q: What is the MOQ and lead time?

Minimum 1 pc accepted for sample evaluation. Volume pricing from 10 pcs. Standard lead time: 7–15 days ex-stock / 20–30 days for production orders. Trade terms: FOB Qingdao / CIF / EXW available.
