Single Row Angular Contact Ball Bearings

Technical Parameters

Engineering Purpose of This Bearing Type

Single Row Angular Contact Ball Bearings are designed to:

• Carry radial load + axial load simultaneously
• Maintain shaft positioning under high-speed rotation
• Reduce friction and heat generation in continuous operation
• Improve system accuracy in precision-driven equipment

This makes them suitable for systems where standard deep groove ball bearings cannot provide sufficient axial load support or stability.

Performance Features

1. Stable Operation Under Combined Loads

The contact angle design allows controlled load distribution between balls and raceways.
This reduces stress concentration and helps maintain alignment in working systems such as pumps and drive units.

2. High-Speed Capability with Controlled Vibration

Precision grinding of raceways and strict internal clearance control help:

• Reduce vibration during high-speed operation
• Maintain smooth rotation under load variation
• Improve noise performance in motor systems

3. Wear Resistance for Continuous Operation

We use high-purity bearing steel with controlled heat treatment cycles to improve:

• Surface fatigue resistance
• Dimensional stability under heat
• Service life in long-running equipment

4. Consistent Batch Quality

All bearings are produced under standardized processes with:

• Automated grinding and assembly lines
• Full dimensional inspection
• Run-out and noise testing before shipment

This ensures stable performance in both small and large-volume orders.

5. Application-Based Technical Support

Bearing selection is matched to actual working conditions, including:

• Load type and direction
• Speed and temperature range
• Lubrication method
• Installation structure

This helps reduce premature failure caused by incorrect selection or mismatch.

Typical Applications

These bearings are widely used in equipment where reliability directly affects productivity:

• Electric motors and industrial drive systems
• Automotive transmission and wheel assemblies
• Water pumps and fluid handling systems
• CNC machines and precision tooling equipment
• Agricultural and construction machinery
• Compressors and automation systems

In these systems, stable bearing performance directly reduces downtime and maintenance cost.
