⚠️ Fitment notice: Always verify OEM part number A0049810705 against your vehicle VIN and axle specification before ordering. Wheel bearing fitment on heavy trucks is safety-critical — incorrect selection may result in bearing failure and loss of vehicle control.
The A0049810705 is a single row tapered roller bearing designed for heavy truck front wheel hub / wheel suspension applications.
Tapered inner ring (cone), outer ring (cup), tapered rollers, and pressed steel cage
High radial and axial load capacity in one direction — typical of front steer axle wheel hub applications
Open design allows field lubrication with wheel bearing grease
Cone and cup assemblies are separable — allows individual replacement
Machined brass cage available for high-load or high-temperature applications
The A0049810705 is a 110×170×47mm tapered roller bearing engineered as a direct OEM replacement for heavy truck front wheel hub / wheel suspension assemblies. At 3.74 kg and 110mm bore, this bearing is designed to withstand the combined radial and axial loads generated by heavy commercial vehicle front axles under fully laden conditions.
The tapered roller geometry provides superior load distribution compared to ball or cylindrical roller bearings, making it the preferred design for heavy truck wheel positions where both radial (vehicle weight) and axial (cornering) forces must be simultaneously managed.
Nexans Bearings manufactures this part to OEM dimensional and hardness specifications (60–64 HRC, GCr15 / AISI 52100 material), with full material traceability and dimensional inspection documentation available on request.

OEM part number A0049810705 is a Mercedes-Benz designation. Always confirm dimensional compatibility (110×170×47mm) when cross-referencing to international bearing brand equivalents. Provide your vehicle model and axle data for a confirmed cross-reference.
Q: What vehicle does A0049810705 fit?
A0049810705 is a Mercedes-Benz OEM part number used on heavy truck front wheel hub / wheel suspension assemblies, including models in the Actros, Axor, and Atego ranges. Always verify against your VIN and axle specification.
Q: Is this the inner or outer wheel bearing?
Depending on the axle assembly, A0049810705 may be used as the inner cone, outer cone, or cup. Confirm the exact position (inner/outer) against your OEM workshop manual or parts catalogue before ordering.
Q: What precision grade should I specify?
P0 (standard) covers the majority of heavy truck aftermarket replacement applications. P5 or P4 is available for OEM supply or applications requiring tighter running accuracy.
Q: What grease / lubrication is recommended?
Heavy truck wheel bearings of this type are typically lubricated with NLGI 2 or NLGI 3 lithium complex or calcium sulfonate wheel bearing grease. Follow your vehicle OEM's lubrication specification and regreasing intervals.
Q: What is the correct installation procedure?
Tapered roller wheel bearings must be installed with the correct preload or end-play as specified in the OEM workshop manual. Incorrect preload on a 110mm bore wheel bearing will cause premature failure. Use a calibrated torque wrench and follow OEM adjustment procedures.
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: OEM / private label available?
Yes. Custom box artwork, laser-engraved part number (A0049810705) and logo on bearing ring, fully branded inner/outer packaging. All IP rights belong to you. MOQ and pricing 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. Shipping: FOB Qingdao / CIF / EXW.
