This AB Tools Trailer Sealed Bearing Kit is designed for commercial or personal use, offering a durable, sealed-for-life solution for trailer hubs. Its primary benefit is providing a waterproof and economical replacement for common trailer axle bearings. A potential caveat is that it's an aftermarket part, requiring verification of compatibility with specific trailer models. The kit includes double-row sealed bearings, circlips, and one-shot hub nuts.

A one-shot hub nut is designed to be tightened to a specific torque and then permanently deformed to lock its position. It is intended for single use and must be replaced whenever the wheel bearing is serviced to ensure proper and safe function.
This kit is designed as an aftermarket replacement for specific ALKO and KNOTT axle and hub assemblies with dimensions 39mm internal diameter and 72mm external diameter. It is crucial to verify these dimensions and compatible part numbers against your trailer's specifications before purchasing.
Sealed-for-life bearings offer extended longevity by protecting against contaminants. However, lifespan depends heavily on usage conditions, load, and maintenance. With proper installation and care, they are designed for durable performance in demanding applications.
Yes, the rubber-sealed design makes these bearings waterproof and highly suitable for boat trailers or any application where the trailer may encounter water.
This kit features a double-row, sealed ball bearing, which offers enhanced protection against water and dirt ingress compared to traditional open bearings. It also includes the necessary circlips and a specific one-shot hub nut for a complete replacement.
Installation typically requires standard automotive tools such as a bearing press (or careful use of a vice/hammer), socket set, torque wrench, and possibly a seal driver. Professional installation is recommended if you are not experienced with trailer hub maintenance.
Ensure the bearing is correctly seated in the hub and not cocked. Verify that the hub nut is tightened to the correct torque specification; overtightening can bind the bearing.
Check that the hub nut is properly tightened. Ensure the circlips are fully seated in their grooves and are the correct size for the hub and stub axle.
Inspect the rubber seals for any visible damage. If compromised, the bearing may need to be replaced. For future prevention, avoid direct high-pressure washing of the bearing area.
Double-check the internal and external dimensions (39mm ID, 72mm OD) against your hub and stub axle. Confirm that the part numbers being replaced match the ALKO or KNOTT references provided.

Care:
While the bearings are sealed for life, periodic visual inspection of the trailer hubs for any signs of damage or leakage is recommended. Avoid using high-pressure washers directly on the bearing seals, as this can potentially compromise their integrity over time.
