Four-Row Cylindrical Roller Bearings

Four-row cylindrical roller bearings can also be supplied as sealed bearings, with a seal at one side or at both sides of the bearing.

The seals are double lip radial shaft seals. Compared with open bearings, sealed bearings offer the following advantages:

Longer service life.
Reduced grease consumption.
Longer relubrication intervals.
Grease leakage and contamination of the rolling emulsion are prevented.
