Cylindrical Roller Bearings

1. Structure and Characteristics Since the rollers of the cylindrical roller bearings make line contact with the raceways, these bearings can support heavy radial loads and are suitable for high speed operation.
Assembly and disassembly are comparatively easy even if the inner or outer ring requires a shrink fit, as the bearing is a separation type.

2.Cylindrical roller bearings are classified as single row, double row and four row type, according to how many rollers are used, and there are models as shown in Table 1 to 3. Although designed as a thin wall type, the SL Model double row cylindrical roller bearing can support enormous radial and impact loads. Table 4 lists the configurations available.
