S B 1210 Self-Aligning Ball Bearing | 50x90x20mm | High Misalignment Tolerance SAB
The S B 1210 is a high-performance Self-Aligning Ball (SAB) bearing designed specifically for applications where alignment between the shaft and housing seating may be imperfect or where shaft deflection is expected. Featuring a double-row design and a convex spherical outer ring raceway, this 50x90x20 mm bearing automatically compensates for angular misalignment up to 2.5 degrees without reducing bearing life or causing edge stress. Constructed from robust bearing steel (e.g., SAE 52100) and equipped with standard C3 internal clearance, the B 1210 maintains low operational friction and running stability even under moderate radial loads and light axial loads.
Optimized for demanding industrial environments, the S B 1210 significantly reduces the risk of premature failure caused by mounting errors or dynamic operational stresses. Its resilience makes it an ideal solution for applications such as textile machinery, conveyor systems, agricultural equipment, and fan units where precise alignment is difficult to maintain. By utilizing the S B 1210, operators benefit from extended service intervals, lower maintenance costs, and improved machine uptime, ensuring long-term operational reliability even in challenging, non-perfectly aligned setups. This part is available in various cage materials (steel or polyamide) depending on speed and temperature requirements.
