Product Description
Hub Unit Bearings Overview
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.
Performance advantages.
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
Continuous Verification, Quality Control and Testing
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.
Rigorous product performance testing
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
