Wheel Hub Bearings
Pre-sealed, pre-lubricated wheel hub bearing assemblies for passenger cars, SUVs, and light trucks — covering 40+ vehicle brands with 200+ models.
The Most Critical Safety Bearing
Wheel hub bearings are among the most safety-critical components in any vehicle. They support the full weight of the vehicle while enabling smooth wheel rotation at highway speeds. A failed wheel bearing can lead to wheel lock-up, loss of steering control, and catastrophic accidents.
OTT wheel hub bearings use double-row angular contact ball structure (DAC type), pre-loaded and pre-lubricated with high-quality grease for lifetime operation. Every bearing undergoes 100% vibration testing before shipment.
Carbonitriding (C-A) Technology
OTT's proprietary Carbonitriding heat treatment improves bearing lifespan by 5–10 times compared to conventional processing. This technology was validated through a rigorous 1,004-hour endurance test conducted by a Russian OEM partner — far exceeding the industry-standard 500-hour requirement.
Seal Configurations
OTT offers 5 seal types (A, B, C, D, E) to match different vehicle requirements and operating conditions — from standard road use to severe off-road and high-temperature environments.
