1. Core Functions

Automotive bearings are critical precision components that support rotating shafts and reduce friction between moving parts.

Reduce friction & wear between rotating and stationary components
Support radial & axial loads from wheels, engines, transmissions, and suspension
Ensure smooth rotation of wheels, crankshaft, camshaft, water pump, alternator, and tensioner
Improve fuel efficiency by lowering mechanical resistance
Stabilize vehicle handling and extend service life of surrounding parts
Absorb vibration and reduce noise during operation

2. Product Design & Material

Materials

Outer & Inner Ring: High-carbon chromium bearing steel (GCr15 / SUJ2) for high hardness, wear resistance, and stability
Rolling Elements: Precision steel balls or rollers, polished to mirror finish
Cage: Nylon PA66, steel, or brass cage for stable rolling element guidance
Seal: Double rubber seals (2RS) or metal shields (ZZ) for dustproof and waterproof protection

Key Design Features

High precision tolerance: P6 / P5 grade for quiet, stable rotation
Double‑sealed design: Prevents dust, mud, water, and sand from entering
Pre‑greased: Lubricated with high‑temperature lithium grease for life‑long lubrication
High load capacity: Suitable for heavy‑duty vehicles, SUVs, and commercial use
Temperature resistance: Operates stably from -40°C to +150°C
Anti‑corrosion: Anti‑rust surface treatment for long‑term durability

3. Application Scope

Our bearings cover the most widely used positions in vehicles:

Wheel Hub Bearing – Front & rear wheels
Clutch Release Bearing – Clutch system
Belt Tensioner Bearing – Engine timing belt & drive belt
Water Pump Bearing – Water pump shaft
Alternator Bearing – Alternator motor
Compressor Bearing – Air conditioning compressor
General Transmission & Engine Bearings

4. Installation Guide

Installation Steps

Clean the mounting seat and shaft thoroughly to remove rust, dirt, and old grease.
Check bearing model and size for perfect match.
Use proper press tools or heating installation to avoid knocking or damaging the bearing.
Do not overload or misalign during installation.
For wheel bearings: use torque wrench to tighten nuts to factory standard.
After installation, check for smooth rotation, no noise, no blocking, no looseness.

Maintenance Notes

Replace bearings in pairs to ensure balance.
Replace immediately if noise, vibration, or overheating occurs.
Do not wash or re‑lubricate sealed bearings; they are maintenance‑free.
