Product Description
Self-Aligning Ball Bearings: Engineered for Precision and Misalignment Compensation
Self-Aligning Ball Bearings represent a robust and versatile solution designed to deliver reliable performance in applications where shaft deflection or misalignment poses a challenge. These bearings feature a unique double-row design of precision balls running within a common spherically grooved outer ring raceway.
Key Features & Benefits
- Superior Misalignment Compensation: Accommodates significant static and dynamic angular misalignment (±2.5° to ±3° typically) between the shaft and housing.
- Reduced Friction & Smooth Operation: Precision-ground balls and raceways minimize friction and lower operating temperatures.
- Robust Construction: Manufactured from high-grade bearing steel with advanced heat treatment for durability.
- Versatile Load Capacity: Handles moderate radial loads and light axial loads in both directions.
- Low Maintenance: High tolerance for imperfect mounting conditions reduces long-term maintenance costs.
Common Applications
Material handling conveyors
Agricultural machinery
Textile machinery
Ventilation and fan systems
Pumps and compressors
Drive systems

Frequently Asked Questions
What makes a ball bearing "self-aligning"?
These bearings have two rows of balls and a common sphered raceway in the outer ring. This design allows the inner ring and balls to deviate within the outer ring to compensate for misalignment.
What is the typical misalignment angle allowed?
Typically, these bearings can accommodate angular misalignment ranging from ±2.5° to ±3°, depending on the specific series and mounting conditions.
Are these bearings suitable for high-speed applications?
Yes, due to the precision-ground balls and low-friction design, they offer smooth operation and are suitable for moderate to high-speed industrial machinery.
Which cage materials are available for these bearings?
Depending on your application requirements, we offer cages made of pressed steel, high-performance nylon, or robust brass.
Can self-aligning ball bearings handle axial loads?
They are primarily designed for radial loads but can accommodate light axial loads in both directions.
What does the "K" suffix represent in models like 1208K?
The "K" suffix indicates a bearing with a tapered bore, which is often used with an adapter sleeve for easy mounting on smooth or stepped shafts.
