Spherical Roller Bearings SKF 22215 E

The SKF 22215 E open spherical roller bearing, measuring 75x130x31 mm, offers high load-carrying capacity and compensates for misalignment through angular movement.

The double-row 22215 E self-aligning roller bearing accommodates high radial loads as well as axial loads acting in both directions. Its barrel-shaped rolling elements move on the spherical outer ring raceway, enabling the bearing to adjust to angular misalignment and compensate for shaft deflection during operation. Manufactured from standard 100Cr6 rolling-element bearing steel in the SKF Explorer design, the bearing is designed for operating conditions in the temperature range from –30 to +200 degrees Celsius.

Under what operating conditions does the 22215 E self-aligning roller bearing operate?

This design is suitable for applications where high radial forces occur in conjunction with misalignment between the shaft and housing. The integrated sheet steel cage guides the roller sets precisely and retains its shape even under dynamic loads. As this is an open bearing without integrated seals, the lubricant can be selected to suit the specific operating environment and supplied via the surrounding housing.

What is the purpose of P5 running accuracy and the lubrication groove in the outer ring?

The bearing combines standard dimensional accuracy PN with the more precise running accuracy of tolerance class P5. This tighter running tolerance reduces runout deviations and promotes smooth rotational behaviour of the shaft. For lubrication, the outer ring features a lubrication groove with lubrication holes. This facilitates relubrication whilst the bearing is installed, as fresh lubricant reaches the rolling element zone directly.
