Trailer Hub Bearings
High-performance wheel hub bearings for car trailers, boat trailers, utility trailers, and recreational vehicle trailers — built to handle heavy loads, road vibration, and exposure to weather.
Why Trailer Bearings Matter
Trailer bearings face some of the harshest operating conditions in the bearing world. Unlike passenger car bearings that benefit from regular maintenance and controlled environments, trailer bearings must endure heavy static loads during parking, sudden dynamic loads during towing, road salt, water splash (especially boat trailers submerged at launch ramps), and long periods of inactivity followed by intense highway use.
OTT trailer hub bearings are engineered with enhanced sealing, corrosion-resistant surface treatment, and high-load capacity to deliver reliable performance across all trailer applications — from lightweight utility trailers to heavy-duty car haulers rated at 3,500 kg ATM and above.
Key Features

- 02 Heavy-duty load capacity for trailers up to 3,500 kg ATM
- 03 Enhanced sealing against water, dust, and road salt
