Spherical Roller Bearings SKF 22312 E

The SKF 22312 E self-aligning roller bearing, measuring 60x130x46 mm, offers high load-carrying capacity, a lubrication groove on the outer ring and enhanced P5 running accuracy for demanding shaft mountings.

The SKF 22312 E self-aligning roller bearing accommodates heavy radial loads as well as combined axial forces and automatically compensates for misalignment or shaft deflection during operation. As a double-row roller bearing in the Explorer performance class, this design has an internal diameter of 60 mm, an external diameter of 130 mm and a width of 46 mm. Manufactured from standard 100Cr6 rolling-element bearing steel, the components are provided with the necessary dimensional stability. Thanks to its open design, the bearing can be integrated directly into lubricated housing assemblies.

In which applications does the 22312 E self-aligning roller bearing prove its worth?

This self-aligning roller bearing is used in bearing arrangements subject to high radial forces and on shafts with low bending stiffness. The self-aligning design automatically compensates for misalignment between the bearing seats during operation. Lubricant can be supplied directly into the bearing via the lubrication groove and lubrication holes in the outer ring. With operating temperatures ranging from -30 to +200 degrees, this design covers a wide thermal operating range.

What are the distinctive features of P5 running accuracy and the sheet steel cage?

The bearing combines standard dimensional accuracy (PN) with the finer running accuracy of class P5. The tighter concentricity tolerance of the P5 class helps to reduce vibrations during operation and supports smooth running at higher speeds. The sheet steel cage guides the rollers whilst maintaining a low weight. As the bearing is of open design and has standard radial clearance, the housing seal and lubricant are selected to suit the operating conditions.
