Refined Technologies and Products for Roads Worldwide Market leading and environment-friendly hub units contributing to vehicle performance and safety on roads worldwide Hub Units - What they are and how they work Hub units are wheel bearings combined with various peripheral parts, which in a single component play a vital role in supporting vehicle motion. JTEKT produces two types, both of which feature high precision and durability: one supports vehicle weight while delivering smooth rotation, and the other does that as well as assisting in the transmission of the driving force from the engine...

JTEKT Hub Units Support Vehicles on Every Road around the World Eco-friendly measures taken at all stages from initial design to manufacturing to daily driving *Example: Hub unit for driving wheel Grease Superior lubrication/fretting resistance Outer side (tire side) Features / Selection Outer seal / Inner seal Fuel Efficiency / Performance High Reliability Superior muddy water resistance also in low friction torque Simultaneous achievement of weight reduction (= fuel efficiency) and increased strength/rigidity (= driving performance) at a high level Inner side (body side) High reliability ensured,...

Answering bearing performance / reliability needs Superior Lubrication / Fretting Resistance Materials Selection Properties required for bearing ring / ball materials High Reliability Excellent rolling fatigue life Grease is injected into the hub unit as a lubricant to maintain bearing function. As standard, JTEKT uses grease with superior quick-acting lubricating performance and superior fretting resistance. High Abrasion Resistance Grease Service Life Use for hub unit bearings/structural parts Inner ring Inner shaft High carbon chromium bearing steels Seizure Resistance Operating Temperature...

Number of Parts Reduced / Weight Reduced Global Technical Support (Bearing Development Bases) Fixed inner ring configuration proposed for 3rd-generation hub unit. Hub Unit for Non-Driven Wheel Compared to the conventional nut fastening method, clinching the shaft end provides weight- and space-saving benefits. Hub unit for Driven Wheel In addition to weight- and space-saving benefits, the need for torque management (axial force) of nut fastening at the time of installing unit in the vehicle is eliminated, thereby simplifying assembly. Assembly work simplified Technical centers located around...
