Automotive hub bearing a generation of hub bearing models are complete
Hub unit bearings must meet increasingly stringent requirements for lighter weight, greater fuel efficiency gains and enhanced modular production systems. With the widespread adoption of anti-lock braking systems (ABS) to ensure stable maneuverability during braking, the demand for wheel unit bearings with built-in sensors continues to grow. nsk guarantees the high quality of all our products through repeated, rigorous bench tests and other inspections that take full advantage of our cutting-edge technology and are only available from top bearing manufacturers. NiuShang offers compact and lightweight hub unit bearings with built-in ABS sensors.
Contact angle optimized to provide specific preload and withstand specific wheel loads
Lightweight and compact design
Variants for all types of vehicles
Anti-corrosion coating adds protection and simplifies disassembly
Low-friction grease and preload range help reduce friction
We audit and verify each component supplier and sub-supplier, including all of their manufacturing, machining and finishing processes.
We perform metallurgical testing of steel for strength and durability, including material composition, cleanliness and heat treatment.
Wheel durability and fatigue testing: verifies strength and structural fatigue performance (resistance to cracking)
Flange runout testing: helps ensure low runout and rotor deflection for better braking performance
Stud twist-off and push-out testing: helps ensure a strong interface between stud and hub to prevent stripping (studs should break first to replace existing hub) - critical for strength and proper installation
Seal durability and performance testing: Seals are mud, high temperature and water spray tested to verify performance and durability.
Bearing Durability Testing: Verifies rolling contact fatigue performance (resistance to spalling damage) to help ensure longer bearing life and improved performance.
ABS Sensor Output Testing: Verifies that sensors meet system requirements and work properly with the ABS/vehicle dynamics system - signal strength, sensitivity, digital output, etc. for passive and active sensors for traction, navigation, and vehicle dynamics control.
Safe start-up process: visual and functional check to ensure ready for installation
Cyclic environmental conditions.
Water spray.
Cyclic dust.
Mud/slurry spray.
Salt spray.

Bearings
Made of ultra-clean alloy steel for increased reliability, performance and life.
Precise internal raceway profile reduces stress on bearing components by distributing the load evenly over the contact surface - increasing load carrying capacity.
Uniform internal geometry, including the contact angles of the inner ring and rollers, allows for precise matching between the outer and inner rings - extending bearing life.
Advanced finishing processes produce smoother surface finishes on races and rollers to reduce friction - helping to improve fuel efficiency.
Seals
High-quality, low-torque, double-lip seals designed for maximum lubrication retention
Enhanced protection against contamination for longer bearing life and durability
Easy to install: reinforced housings help prevent installation damage and improve durability
Enhanced sealing: Ribbed rubber bore is designed to seal minor spindle defects and promote spindle alignment.
Prevents seal lip damage: Internal contamination exclusion system helps prevent penetration of debris that could lead to leaks.
Optimal seal life: Vent holes allow lubricant to flow freely around the seal lip - cooling the seal assembly and eliminating heat buildup.
ABS Sensors
Designed to continuously monitor wheel speed, road conditions and work in concert with other systems in the vehicle - for reliable and better braking performance.
Studs
Made of clean, high-quality, high-alloy steel for rugged strength and durability.
