Product description：

This double-row self-aligning ball bearing is an open bearing, and has a tapered bore, pressed steel cage, and C3 clearance rating. It is suitable for applications supporting moderate radial loads and moderate to low thrust loads. This bearing has concave sphered housing rings to compensate for static angular misalignments between the shaft and housing in applications subject to shaft deflections or mounting errors. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds. The bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. The bearing has a tapered bore with a standard 1:12 taper to compensate for shaft deflection or to mount on a tapered shaft using an interference fit. Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has a C3 radial internal clearance designation to indicate that the radial slack between the inner and outer rings is greater than the standard CN (normal) clearance. It allows for thermal expansion as the bearing supports radial loads and its balls, operating in the deep raceway geometry, reduce rotational friction. Additionally, this bearing is produced to normal tolerances in accordance with International Organization for Standardization (ISO) 492:2002 standards for quality assurance. This self-aligning ball bearing is for use in commercial and industrial applications including film processing equipment, office automation, vertical spinning equipment, and industrial countershafts, among others.

Product features：

Self-aligning bearing for applications subject to shaft deflections or misalignments between the shaft and housing

Tapered bore with 1:12 taper for compensating for a flexing shaft or fitting to a tapered shaft

Open configuration for lubrication applied in place

Pressed steel cage evenly spaces balls for reduced friction, vibration, and noise

C3 radial internal clearance is larger than normal allowing for thermal expansion
