Product Description

With over 20 years of manufacturing experience, we have observed a common issue in industrial applications:

standard thrust bearings often fail to maintain stable precision under continuous high axial loads and long operating cycles.

The Axial Angular Contact Roller Bearings SGL Series was developed specifically to address this limitation by improving:

Roller contact geometry

Preload stability control

Heat resistance under high-speed operation

Load distribution consistency

Compared with conventional thrust bearings, the SGL Series delivers higher rigidity and more stable rotational accuracy, especially in precision positioning systems.

Key Performance Advantages

High Axial Rigidity Structure

The optimized roller geometry increases the effective contact area between rollers and raceways.
This design reduces elastic deformation and significantly improves load-bearing stability, helping maintain accurate positioning under heavy axial force.

Precision Raceway Grinding

All raceways are manufactured using automated grinding lines and strict dimensional control systems.

This results in:

Lower operating noise
Reduced friction heat
Improved surface fatigue resistance
Minimal micro-vibration

These advantages are especially important for CNC machinery and high-speed automation systems.

Stable Material Performance

The Axial Angular Contact Roller Bearings SGL Series is ideal for systems requiring high-precision axial control and stable rotation, including:

High wear resistance
Stable dimensional accuracy
Strong fatigue life performance
Excellent anti-deformation capability

Optional material and surface treatments are available for humid, corrosive, or special operating environments.

Typical Applications

The Axial Angular Contact Roller Bearings SGL Series is ideal for systems requiring high precision axial control and stable rotation, including:

CNC machine tool spindles
Rotary indexing tables
Precision automation equipment
Injection molding machines
Servo-driven heavy-load systems

In continuous production environments, stable axial performance helps reduce downtime and maintenance frequency.

SGL Series vs Standard Thrust Bearings

Performance Factor	Standard Thrust Bearings	SGL Series Bearings
Axial Load Capacity	Medium	High
Positioning Accuracy	Standard	Precision Grade
High-Speed Stability	Moderate	High Stability
Structural Rigidity	Lower	Higher
Heat Resistance	General	Improved
Continuous Operation	Average	Stable & Long-Life

Recommended Operating Conditions

The SGL Series is recommended for:

Continuous industrial operation
High axial load systems
Precision positioning equipment
Low-vibration requirements
Frequent start-stop applications

For extreme environments (dust, humidity, high temperature), lubrication and sealing configuration should be matched to operating conditions.
