SKF 3308 A C3 Double Row Angular Contact Ball Bearing with 40 mm bore delivers high load capacity and smooth, reliable operation for precision machinery in back to back mounting and C3 clearance advantages

SKF 3308 A/C3 Double-Row Ball Bearing, 40mm bore
✔️ 40 mm bore, double-row 30° contact, open, single pack, SKF Explorer

This SKF 3308 A/C3 bearing is a double-row, back-to-back arrangement built for high radial loads and precise shaft alignment in industrial drives, gearboxes, conveyors, and machine tools. It uses a sheet metal cage and a one-piece inner and outer ring design, with no seal or relubrication built in, making it ideal for cleanroom or controlled environments where lubrication comes from the system.

✅ ✅ Double-row back-to-back arrangement for rigid axial load handling
