Spherical Roller Bearings FAG 23938 -S-K-MB

The FAG 23938 -S-K-MB self-aligning roller bearing, measuring 190 x 260 x 52 mm, with a brass cage and tapered bore, offers a robust solution for demanding industrial applications.

The FAG 23938 -S-K-MB self-aligning roller bearing is a double-row roller bearing designed for high radial loads combined with simultaneous axial forces. Thanks to the spherical raceway in the outer ring, the design automatically compensates for misalignment and shaft deflection during operation. The open bearing, made from standard rolling-element bearing steel 100Cr6, has standard radial clearance and is designed for a temperature range of -30 to +200 degrees Celsius.

What is the 23938 -S-K-MB self-aligning roller bearing suitable for?

This rolling bearing is used in demanding industrial applications where heavy radial forces and combined axial loads occur. Wherever high loads act on shafts with a diameter of 190 mm and operational shaft deflection or misalignment needs to be compensated for, this design ensures smooth running. The integrated lubrication groove with lubrication holes in the outer ring facilitates relubrication during operation, ensuring that lubricant reaches both sets of rollers directly.

What are the special features of the tapered bore and brass cage?

The design with a tapered bore with a taper ratio of 1:12 allows for precise mounting directly onto tapered shaft seats or using suitable clamping and withdrawal sleeves. The radial operating clearance can be precisely adjusted during installation via the axial displacement. The solid brass cage guides the rolling elements accurately, even under vibration or shock loads. As an open component without an integrated seal, the bearing requires external sealing of the bearing housing.
