Product Description
RCK25-420x670 Shaft Clamping Element
No need for a Torque Wrench with these Clamping elements, just tighten the screws in clockwise sequence in stages until the front faces of the flange and outer ring are aligned. This allows the transmission of torque values shown in the table. This overcomes the problems often encountered where units are either under or over tightened causing failures in transmission. There can also be a time saving in that powered tools can be used for the belt tightening.
Increased torque capacities are achieved by the use of larger screws. The single block design automatically provides parallel setting of the parts, thereby reducing the need for dynamic balancing.
