Nsk Ball Bearing

Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.

The bearings comprise solid outer nsk ball bearing rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.

The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place.
