SA050AR0 Bearing Product Overview & Core Advantages
The SA050AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. Constructed from stainless steel, it offers excellent corrosion resistance. Its single-row design with a 30° contact angle is specifically configured to support combined loads, efficiently handling substantial radial and axial forces simultaneously. This bearing is ideal for compact assemblies where high rigidity and accurate rotational performance are critical.

SA050AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and stainless steel construction provide high rigidity, enabling the bearing to support significant combined radial and axial static loads (1840 lbf radial, 1690 lbf axial).
- Precision Performance: Manufactured to ABEC-1 tolerance class, this bearing ensures consistent running accuracy and smooth operation, making it suitable for precision instruments.
- Corrosion Resistance: The use of stainless steel for both rings and balls makes the SA050AR0 ideal for applications exposed to corrosive environments or requiring washdown.
- Space-Saving Design: As a thin-section bearing with a cross-section of only 0.25", it allows for lightweight and compact machinery designs without sacrificing performance.
- Optimized Lubrication: The "R" suffix indicates a filling slot, facilitating efficient re-lubrication to maintain performance over the bearing's service life.
