SC120AR0 Bearing Structural Features & Performance Benefits

Thin-Section Design: With a cross-section of only 0.375" and large 12" bore diameter, this bearing provides maximum space savings while maintaining structural integrity. The ultra-thin construction enables compact machine designs without compromising load capacity.

Superior Load Capacity: The 30° contact angle configuration enables the bearing to efficiently handle combined radial and axial loads. With a radial dynamic load rating of 2147 lbf and axial static load rating of 5570 lbf, it delivers robust performance in demanding applications.

Precision Engineering: Manufactured to ABEC-1 tolerance standards with stainless steel rings and balls plus brass cage, this bearing ensures smooth operation and extended service life. The tight radial internal clearance of 0.0000-0.0005" provides precise rotational accuracy.

Corrosion Resistance: Constructed entirely from stainless steel materials, the SC120AR0 offers excellent corrosion resistance, making it suitable for harsh environments, washdown applications, and food processing equipment.
