Curve roller bearing is assembled with a bolt shaft, thick-walled outer ring and other bearing parts. The thick-walled outer ring can carry shock load and reduce deformation and bend stress. Hexagon nut in bolt shaft can make it easy to assemble on machine. This kind of bearing mainly used in rollway transmission machine.

Main characteristic

►Bear shock load and reduce deformation and bend stress

►Bolt as shaft, easy to assemble with nut

►Different structure, widely using
