2 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 to the wheel. Beginning with the consideration of the car s overall construction to the environmental impact of our manufacturing techniques, JTEKT hub units are built to be lightweight with low rotating friction to enhance fuel efficiency, while maintaining the strength and rigidity that ensures optimal driving performance. JTEKT hub units have evolved from the conventional 1st-generation design to the current advanced 3rd-generation configuration, which we most recommend to customers, by integrating flanges that facilitate their installation to vehicles. 1st-generation: Two single rows integrated into a double-row unit 2nd-generation: Integrated one flange on outer ring 3rd-generation: Also inner ring integrated with flange Trend Generational Evolution (Unitization) Increased added-value: size/weight reductions 3rd-generation Clinched haft End Hub Unit Development Approach Easy Assembly High Reliability Lightweight Long ervice Life afety Factors 2nd-generation Active ensor / Magnetized Pulser 1st-generation Built-in ensor 3rd-generation hub unit 2nd-generation hub unit 1st-generation hub unit High ealing Performance Low Torque Double-lip seal Pack seal Double Axial Lip eal Deflector eal In parallel with the evolution of automobiles, JTEKT hub units have been widely adopted by not only automotive manufacturers in Japan, but manufacturers around the world.

The magnetized pulser is a multipolar magnet applied to a pulser ring: a rubber composite is filled with magnetic material and then segments are alternately magnetized with orth and outh poles, taking the bearing rotation shaft as the point of origin. Using the magnetized pulser enables more reliable detection of wheel speed.
