YDTech® manufacturer of customized wedge roller blocks for (fishing gear, fishing gear)! supplier of wedge rollers, shafts for one way wedge bearings and clutces in china!

we produce various roller wedges from customer drawings. in assembling, be careful to prevent the outer ring from twisting. Avoid to hammer directly the outer ring and, in press-fitting, bring a proper jig in contact with the outer ring side face without fail. Furthermore, when press-fitting in an housing with shoulder, good care must be exercised to prevent the bearing side face from coming into contact with the housing shoulder and to thereby avoid deformation of the bearing.

also, shaft can be easily assembled by turning it in clutch idling direction. Where impossible to do so, provide the shaft end with a tapered guide to facilitate assembling-in.
