• The dimensions of TCFFD-B/K follow those of TCFFD-A.
• The allowable radial direction displacement represents the case eccentricity and tilt angle are zero.
• The eccentricity and tilt angle act simultaneously, the allowable tilt angle has restricted.
• The maximum rotational speed does not consider dynamic balance.
• For bolt clamp hubs, the recommended shaft tolerance is h6.
• For bolt clamp hubs, after pushing the shaft into the designated position, tighten two of the hub’s clamping bolts alternately in 2-3 steps to the specified tightening torque. Tighten the other two clamping bolts on the opposite side in the same manner.

Feature

• They unitized the double plate spring part for high torque transmission. You can combine it with any type of shaft coupling method.
