Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

 

A cage-guided cylindrical roller bearing helps keep the rolling elements in place, which becomes more crucial as loads get heavier. A cylindrical roller bearing can support light-thrust movement, with the double-row type also able to support axial loads in both directions.Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface.
