WJB WA512570HD Heavy Duty Wheel Bearing and Hub Assembly

The WJB WA512570HD is a Heavy Duty (HD) wheel bearing and hub assembly engineered to deliver enhanced durability and performance over standard replacement units. Part of WJB's upgraded HD line, this assembly is a direct OEM-style replacement designed to restore proper wheel rotation, load support, and ABS sensor function.

WJB's HD hub assemblies feature advanced roll forming technology with a signature zero-gap design between the flange and inner ring, providing precise bearing preload and preventing issues caused by over-torquing. The increased steel ball capacity — up to 20–30% more than standard assemblies — reduces friction, lowers operating temperatures, and extends overall hub life.

Key Features:

• Advanced Roll Forming Technology — precise bearing preload for improved strength and secure clamping to the CV joint and knuckle
• Increased Steel Ball Capacity — 20–30% more ball capacity than standard assemblies for reduced friction and cooler operation
• High-Performance Grease — high-grade lubrication with fatigue-resistant additives to withstand extreme pressure
• Zero-Gap Flange Design — eliminates over-torquing risk and ensures accurate bearing preload
• Pre-Assembled, Bolt-On Installation — integrates the wheel bearing, spindle hub, wheel seal, and mounting flange into one ready-to-install unit; no special tools required
• Corrosion-Resistant Wheel Studs — pre-installed studs with special coating to resist corrosion and prevent loosening
• ABS Compatible — where applicable, pre-installed speed sensor automatically syncs with the vehicle's anti-lock braking system and is verified to be compatible with OE systems
• Heat-Treated Construction — cold-forming and heat treatment processes harden the surface for high-temperature resistance and long-term durability
• Reinforced Seal Design — optimized sealing materials for reliable performance in harsh environments
• OEM Fitment — engineered and tested to meet or exceed original equipment specifications

All WJB HD wheel hub assemblies are manufactured in ISO/TS 16949 certified facilities and are backed by a 12-month manufacturer's warranty against defects.
