QY955
Type DC is a sprag type freewheel cage without inner or outer races. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing. The DC type version-N accepts all types of lubricants currently used in the power transmission equipement.
Surface hardness of the finished part should be HRC 60 to 62, for a depth of 0,6 mm minimum.
Core hardness to be HRC35 to 45.
Surface hardness of the finished part should be HRC 60 to 62, for a depth of 0,6 mm minimum.
Core hardness to be HRC35 to 45.

FXM Freewheel One Way Clutch BearingIntegrated Freewheels FXM are sprag free -wheels without bearing support and with sprag lift-off X.The sprag lift-off X ensures freewheel one way clutch operation when the inner ring rotates at high speed. The freewheels FXM are used as: 1. Backstops 2. Overrunning Clutches for applications with high speed freewheeling operation and when used as an overrunning clutch with low speed driving operation. Nominal torques up to 888 000 N.m. Bores up to 460 mm. Many standard bores are available.QY810Send Inquiry
AV Series Backstop ClutchType AV is a roller type freewheel. It is self-contained, centered by plain bearings for low rotational speeds , and sealed using shield protected metallic labyrinth seals. Unit is delivered grease lubricated, ready to install in a horizontal or vertical position. Primarily used as a backstop, the torque capacity is high for a minimum space requirement. This design is suitable for use in difficult environments. A bolt, secured to a fixed part of the machine and passing through the slot in the torque arm, provides the rotational stop. Radial clearance on this bolt should be equal to 1-3 % of the slot width. The torque arm and the bearings must not be prestressed. The roller design makes the AV type ideal for light indexing applications.QY809Send Inquiry
Backstop Clutch BSEUBSEU series Cam Clutch was developed as European style Backstopping Cam Clutch which has easy usage. It has Cam & Roller construction that the roller works as a bearing same as the small size BS series Cam Clutch. The outer race has special shape which was combined the torque arm, so only stopping the rotation is required. You can select the correct model from various bore size from 20 mm to 90 mm in each 5 mm. Backstopping for the country elevator or the foods conveying conveyor which is used in the factory is the recommendation. The recommends BS series Cam Clutch in the very dusty environment condition or the inclined conveyor and the bucket elevator which are used in outside location.QY808Send Inquiry
RSBW Backstop ClutchStructure: Type RSBW is a DC sprag type freewheel. It is self-contained, centered by plain bearings for low rotational speeds, and sealed using shield protected O rings. Installation : The design allows installation in difficult environments such a high humidity or water splash areas. A bolt, secured to a fixed part of the machine and passing through the slot in the torque arm, provides the rotational stop. Radial clearance on this bolt should be equal to 1-3% of the slot width. The torque arm and the bearings must not be prestressed .QY807Send Inquiry
