Spherical Roller Bearings SKF 22312 E/C3

The SKF 22312 E/C3 self-aligning roller bearing, with dimensions of 60x130x46 mm and increased C3 clearance, is designed to support shafts under high radial loads.

The 22312 E/C3 self-aligning roller bearing is made from standard rolling-element bearing steel (100Cr6) and accommodates heavy radial loads as well as axial forces in both directions. Thanks to its barrel-shaped rollers, the component automatically compensates for misalignment and shaft deflection during operation. The open bearing features a robust sheet steel cage and is suitable for a temperature range of -30 to +200 degrees. A lubrication groove with integrated lubrication holes on the outer ring facilitates the supply of lubricant directly into the interior of the rolling element raceway.

What is the 22312 E/C3 spherical roller bearing suitable for in operation?

Design engineers select this design primarily for demanding industrial applications involving heavy shock loads, vibrations or significant shaft deflection. Typical areas of application include industrial drive systems and heavy machinery subject to dynamic loads. As the 22312 E/C3 self-aligning roller bearing compensates for angular misalignment between the shaft and housing, it counteracts undesirable edge stresses on the rollers. This helps to reduce wear and promote smooth running even under high loads.

What do the C3 bearing clearance and tolerance class P5 mean for selection?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance is advantageous when tight fits cause the inner ring to expand or when temperature differences between the inner and outer rings reduce the operating clearance. In this bearing, SKF combines dimensional accuracy PN with the increased running accuracy of class P5. This enables you to achieve particularly precise concentricity. Due to the open design, sealing is provided by the surrounding housing structure, whilst the lubricant can be replenished as required.
