SKF Bearing 3211 A Double Row Angular Contact Back To Back DB Bearing 55 mm Bore Sheet Metal Cage Bearing Steel 61 kN Dynamic Load 52 kN Static Load No Outer Ring Locator

SKF 3211 A double-row bearing with 55 mm bore
✔️ 2-row back-to-back, CN clearance, 55 mm bore, no seal

This SKF 3211 A is a heavy-duty double-row angular contact bearing built for machines that demand high rigidity and smooth motion. The back-to-back arrangement supports axial loads in both directions and is commonly used in CNC machines, presses, and conveyor systems where precision and stability matter. It uses CN clearance, a sheet metal cage, and one-piece inner/outer rings for reliable performance in open lubrication environments.

✅ Bore: 55 mm (2.17 in)
✅ Outer diameter: 98.7 mm (3.89 in)
✅ Width: 33.3 mm (1.31 in)
✅ Dynamic load rating: 61 kN
✅ Static load rating: 52 kN
✅ Limiting speed: 6300 r/min
