B1004E 3rd generation Ball Hub Units

Product catalog summary

Overview: The document discusses the evolution and features of JTEKT's 3rd-generation ball hub units, emphasizing their easy assembly, high reliability, lightweight design, long service life, and safety factors. These units are integral to vehicle performance, supporting weight and facilitating smooth rotation while transmitting engine power to the wheels.

Generational Evolution: The hub units have evolved from the 1st-generation, which integrated two single rows into a double-row unit, to the 3rd-generation, which integrates both the inner and outer rings with flanges. This evolution has increased added value through size and weight reductions.

Key Features: The 3rd-generation hub units include built-in sensors, active sensors, and magnetized pulsers. They are designed for high sealing performance, low torque, and superior muddy water resistance. The units are also eco-friendly, contributing to fuel efficiency and vehicle performance.

Materials and Design: JTEKT uses high-quality materials like carbon steels and high carbon chromium bearing steels, ensuring high reliability, excellent rolling fatigue life, and high abrasion resistance. The design focuses on reducing weight while maintaining strength and rigidity.

Technical Specifications: The document provides detailed specifications for various hub unit models, including dimensions and recommended setups based on vehicle axle load. It also highlights the benefits of shaft end clinching over traditional nut fastening, simplifying assembly and reducing weight.

Testing and Global Support: JTEKT conducts rigorous testing at the Iga Proving Ground, simulating various road and weather conditions to ensure product safety and performance. The company offers global technical support with centers in Japan, the Americas, Europe, China, and Southeast Asia.

Contact Information: The document lists contact details for JTEKT offices worldwide, providing support and sales information for various regions.
