• The dimensions of TCFFS-B/K follow those of TCFFS-A.
• The allowable radial direction displacement represents the case when eccentricity and tilt angle are zero.
• 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. Afterward, tighten the other two clamping bolts on the opposite side in the same manner.
