cylindrical roller bearings

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.

 

Based on the theory that oil film formation in bearing contact areas can be improved by changing the character and direction of the components’ surface finishes, the distinguishing micro pots are able to effectively capture and channel oil to where it’s needed.

 

Cylindrical Roller Bearings - NUB Series. In order to meet the requirements of steel making equipment and continuous-casting machines, We have expanded its range of cylindrical roller bearings. We have developed the new NUB series which can reduce the total cost of ownership for continuous casting machine guide rolls.
