Spherical Roller Bearings FAG 23956 -MB

The 23956 -MB spherical roller bearing from FAG Wälzlager, with dimensions of 280 × 380 × 75 mm and a brass cage, offers high load-carrying capacity for large industrial gearboxes and heavy-duty shaft mountings.

The 23956 -MB self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) for demanding industrial applications. It accommodates high radial loads as well as combined axial forces. Thanks to its barrel-shaped rollers, the bearing automatically compensates for misalignment and shaft deflection during operation. Designed as an open bearing, this version requires an external housing seal and is suitable for operating temperatures ranging from -30 to +200 degrees.

What is the 23956-MB self-aligning roller bearing suitable for?

This large bearing is primarily used in heavy-duty mechanical engineering and industrial gearboxes. The design proves its worth in applications where rigid mountings would be overloaded due to shaft deflection or misalignment. Thanks to the design of the rolling elements, the component transmits high forces whilst maintaining a constant rotational movement. In enclosed machine housings with a controlled lubricant supply, the roller bearing operates reliably under demanding conditions.

What are the advantages of a brass cage and lubrication groove?

The bearing features a brass cage (suffix -MB), which is more resistant to shocks, vibrations and high acceleration forces than standard sheet metal cages. For relubrication, the outer ring has a lubrication groove with integrated lubrication holes. This allows the lubricant to reach directly between the two rows of rollers. Manufacture to tolerance class P0/PN or ABEC 1, with standard radial bearing clearance, ensures a precise fit under normal installation and operating conditions.
