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

4. Installation Guide

Installation Steps

1. Clean the mounting seat and shaft thoroughly to remove rust, dirt, and old grease.
2. Check bearing model and size for perfect match.
3. Use proper press tools or heating installation to avoid knocking or damaging the bearing.
4. Do not overload or misalign during installation.
5. For wheel bearings: use torque wrench to tighten nuts to factory standard.
6. 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.
