Product Brief :
Use the EDi Locking Element, do not need to have the shaft and wheel heart (hub) to do keyway processing work, also can convey high torque. At the same time, the position of axial direction can be adjusted conveniently.

  
   

Typical applications:

The Locking Element of YiDi is used to convey the power of the shaft and wheel heart without keyway processing. Because the device does not have a keyway, the parts are strengthened and more power can be conveyed effectively.
YiDi of the Locking Element used to bear axial force, and the fixed shaft parts, also used in rotary torque, and fixed axis of rotation, chain wheel, the axis of rotation, the synchronous belt wheel and gear, to convey the power.

An example of consulting / ordering of Locking Element:
1). Type - inner diameter + outer diameter
Z3 or DR132, inner diameter d = 25mm, outer diameter d = 50mm
Z3-25 * 50 or DR132-25 * 50
2). The type is not clear: inner diameter, outer diameter, height
