Spherical Roller Bearings FAG 23936 -S-MB

The FAG 23936 -S-MB self-aligning roller bearing, with a 180 mm bore and a brass cage, offers high load-carrying capacity for demanding industrial applications.

The 23936 -S-MB self-aligning roller bearing accommodates high radial loads as well as simultaneously acting axial forces in both directions. Thanks to the hollow-spherical outer ring raceway, the design automatically compensates for misalignment and shaft deflection during operation. This open roller bearing, made from standard bearing steel 100Cr6, has the main dimensions 180 x 250 x 52 mm. It is designed for operating temperatures ranging from –30 to +200 degrees Celsius and can be relubricated as required whilst installed.

In which operating situations does the 23936 -S-MB self-aligning roller bearing compensate for misalignment?

Designs featuring long shafts or flexible housing assemblies benefit from this bearing’s angular-contact design. Should housing misalignment or load-induced deflection occur, the roller set adjusts to match the outer ring raceway. The component compensates for angular misalignment between the shaft and housing without any measurable increase in friction. Thanks to its open design, users can select the appropriate lubricant themselves, depending on the ambient conditions and the rotational speeds at the respective bearing location.

What are the distinctive features of the version with a brass cage?

The version with a brass cage (identified by the suffix MB) guides the rolling elements precisely through the load zone. The solid brass material withstands high accelerations and vibrations, and mechanically dampens shock loads. Furthermore, the material exhibits high dimensional stability even at operating temperatures of up to +200 degrees Celsius. To ensure a uniform supply of grease or lubricating oil, the outer ring is fitted as standard with a circumferential lubrication groove and radial lubrication holes.
