Spherical Roller Bearings SKF 22220 EK

The SKF 22220 EK self-aligning roller bearing (100x180x46 mm) accommodates heavy radial loads and misalignment, and features an easy-to-fit tapered bore.

The SKF 22220 EK self-aligning roller bearing is a double-row roller bearing designed for demanding industrial applications involving heavy radial forces and axial loads on both sides. Manufactured from standard 100Cr6 bearing steel in the Explorer design, the open construction is rated for operating temperatures from –30 to +200 degrees Celsius. Thanks to the hollow spherical raceway in the outer ring, the design automatically compensates for shaft misalignment. An integrated lubrication groove with lubrication holes in the outer ring facilitates relubrication during operation.

What is the 22220 EK self-aligning roller bearing suitable for?

This rolling bearing is suitable for heavy-duty applications in general mechanical engineering where shaft deflection or misalignment between the inner and outer rings occurs. Typical applications include industrial bearings subjected to high loads and misalignment between the shaft and housing. Thanks to the sheet steel cage, the bearing guides the barrel-shaped rollers with low vibration, even under high loads and at varying speeds. Designers prefer to use the open design in enclosed housings where grease or lubricating oil is supplied regularly via the outer ring.

What are the advantages of the tapered bore with a 1:12 taper?

The tapered internal bore with a taper ratio of 1:12 allows for easy mounting directly onto tapered shaft seats or, using suitable mounting and withdrawal sleeves, onto cylindrical shafts. During mounting, the standard radial bearing clearance is reduced in a controlled manner, allowing you to precisely set the required operating fit. Furthermore, this design is characterised by increased running accuracy to tolerance class P5 with standard dimensional accuracy PN. This ensures smooth concentricity in demanding industrial applications.
