      ZHH The curve roller bearing consists of a bolt and a thick-walled outer ring as a roller inner race. The shoulder of the bolt shaft and the end ring on the bolt form the guide surface of the outer ring in the two lateral directions.
When the curve roller in the flat raceway or cam plate movement, due to the elastic deformation of the outer ring, roller internal stress increases. So apply to the rated load selection in this case as a curve wheel.
The rear stop "X" is indicated as a cylindrical outer surface, and the basic load C and Co are used when the bearing outer ring (with outer cylindrical surface) is fitted in a seat with a normal bearing fit; when used as a roller, Load Cw and Cow.
