SG220AR0 Bearing Product Overview & Core Advantages
The SG220AR0 is a stainless steel thin section bearing designed for applications requiring compact design and corrosion resistance. As a single row angular contact ball bearing, it excels at handling combined loads, simultaneously supporting substantial radial loads and high unidirectional axial thrust. Manufactured to ABEC-1 precision standards with a 30° contact angle, this bearing delivers reliable performance in space-constrained, high-reliability environments. Its all-stainless steel construction ensures excellent corrosion resistance, making it suitable for demanding operational conditions.

SG220AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The compact cross-section (1" width) enables significant space and weight savings in machinery design while maintaining high load capacity.
High Load Capacity: The 30° contact angle and optimized raceway geometry provide exceptional combined load handling, with a radial dynamic load rating of 14,290 lbf and axial static load rating of 37,712 lbf.
Corrosion Resistance: Constructed entirely from stainless steel components (rings and balls) with a brass cage, offering superior protection against corrosion in harsh environments.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005") ensuring smooth operation and precise positioning.
Wide Temperature Range: Suitable for operation from -30°C to 110°C, accommodating various industrial temperature conditions.
SG220AR0 Bearing Typical Application Areas
The SG220AR0 thin section angular contact bearing is ideally suited for:
- Aerospace & Defense Systems: Actuators, control mechanisms, and radar positioning systems
- Medical Equipment: MRI scanners, surgical robots, and diagnostic imaging devices
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages
- Food Processing Machinery: Where corrosion resistance and clean operation are critical
