Four-row Cylindrical Roller Bearing

Four-row cylindrical roller bearing can be subject to major radial load and impact load. It is provided with high machining precision, and is applicable for high speed.

Grind the inner raceway surface and the roller surface simultaneously after press the inner race into roller path. This is favorable for enhancing rolling precision, and mounting windage of the bearing can be freely adjusted.

The bearing are mainly applied on the working roll or supporting roll of machines such as cold mill, hot mill and roughing mill etc, it can also be applied on other occasions.
