Double Row Angular Contact Ball Bearings (General) 3310 ATN9

Double Row Angular Contact Ball Bearings (General) 3310 ATN9

The 3310 ATN9 is a double-row angular contact ball bearing with a 50mm bore and 110mm outer diameter, designed to handle both radial and axial loads. Its chrome steel construction ensures durability, while the nylon cage reduces friction for smoother operation.

With a dynamic radial load capacity of 21375 lbf, it can handle heavy-duty applications. The bearing spins efficiently at speeds up to 6000 RPM and operates in temperatures from -30°C to 110°C.

Its open design allows easy lubrication, and the P6 tolerance class ensures precise performance. The double-row setup provides better stability under angular loads.

Ideal for industrial machinery, gearboxes, or pumps where combined loads are common. Weighing 1.7kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards.
