(Refer to Fig. 5) In addition, the upward and lateral load rating is the 1/2 of the load 1/2 of the load same as downward load rating. For the CRW series, since the number of cylindrical rollers that share load of Load direction Load Load each direction varies, the load rating for each load direction and allowable load must be obtained.
