Colección: Semi Truck Wheel Bearings, Bearing Kits & Seals

Start by identifying the component you need. This collection includes individual semi truck wheel bearings, F-Box bearing kits for selected differentials or gearboxes, one drivetrain center bearing, and one trailer axle wheel seal. These products serve different locations and should not be treated as interchangeable simply because they all use the word “bearing” or appear in the same collection.

For an individual wheel bearing, determine the axle position first. The current products identify steering, drive, or trailer axle applications. Then compare the bearing set or manufacturer part number, inner diameter, outer diameter, width, and the cross-references published on the individual product page. A visual match alone is not enough to establish the correct replacement.

For an F-Box, use the exact FDRK or FTRK kit code and the OEM reference for the differential or gearbox being serviced. Review the listed components because kit contents vary. The 412-E center bearing and 42623 trailer axle seal are separate component types, so match those products using their own part numbers and application information. If any number or dimension is unclear, confirm it before ordering.

An individual wheel bearing is a single bearing set listed for a particular axle position. The collection currently includes products identified for steering, drive, and trailer axles. Their product pages publish dimensions and cross-references that can be compared with the bearing being replaced.

An F-Box is a multi-component kit for a selected differential or gearbox. Depending on the exact kit, its listing may include several bearings plus seals, rings, bushings, gaskets, washers, or other related components. Always use the exact FDRK or FTRK code and review the contents of that specific listing. Do not assume that an F-Box is a wheel-end bearing kit.

The six individual semi truck wheel bearings are identified for steering, drive, or trailer axle applications. The product title indicates the axle position, followed by a bearing set or part number. That axle label helps narrow the selection, but it does not replace verification of the exact bearing dimensions and references.

Start with the truck or trailer component being serviced, then compare the existing bearing number with the individual product page. Do not move a bearing from one axle category to another based only on similar dimensions or appearance.

Compare all published identifiers rather than relying on one field. The individual bearing pages may list an inner diameter, outer diameter, total width, manufacturer part number, and references from brands or vehicle manufacturers. The values must describe the same bearing set you are replacing.

A cross-reference is a matching aid, not permission to ignore dimensions or application. If the number on the removed part, the published dimensions, and the axle position do not agree, stop and confirm the application before purchase. Product-specific measurements remain on each product page so they can be checked against the physical component.

Yes. The current collection includes the 42623 SKF trailer axle seal sold as a four-pack. Its product title identifies National 370065A and Stemco 373-0123 as cross-references. It is a trailer axle wheel seal, not a wheel bearing or a complete bearing kit.

Use the exact seal number and application information when evaluating it. The phrase semi truck wheel seals describes this part type, but the collection does not imply that the 42623 seal fits every truck or trailer axle. Confirm the reference before ordering.

No. The 412-E center bearing is listed as a drivetrain support component, while a wheel bearing operates at a wheel-end or axle position. They address different component locations and should not be selected using the same criteria.

For the 412-E, verify the exact part number and drivetrain application. For a wheel bearing, use axle position, bearing numbers, dimensions, and cross-references. Keeping these component types separate prevents the shared word “bearing” from creating the wrong match.

Begin with the exact assembly being serviced and its OEM reference. Then compare that information with the FDRK or FTRK kit code shown in the product title and description. The listings identify kits for different differential or gearbox assemblies, and their component lists are not identical.

Review every included part shown on the selected product page. Some kits list seals, gaskets, rings, bushings, washers, or nuts in addition to bearings, while others publish a shorter component list. Do not choose solely by price, the F-Box image, or another kit with a similar code.

Do not order based on appearance or a partial number. Record the complete number on the removed component, the axle or drivetrain position, the equipment information, and any available measurements. Compare that information with the exact title and specifications on the product page.

If a listing is incomplete, inconsistent, or does not show the same identifiers, request confirmation before purchasing. This is especially important when selecting semi truck wheel bearings or multi-component kits because a similar-looking part can correspond to a different position or assembly. Product-page information should govern the final selection.
