Product Description
RCK20-340 x 570 Shaft Clamping Element
Types RCK19 & 20 are normally referred to as clamping discs, used
to clamp externally onto thin walled hubs to lock them to the shaft.
The design permits the use of large diameter shafts with small hub
sizes, and is popular for connection of large sprocket and pulleys. The
design provides for optimum concentricity, with high torque transmission. A number of shaft diameters can be accommodated by
one size of unit, max., min. and an intermediate being shown in the attributes.
Recommended tolerances:
Hub Outside Ø: h8
*Hub Bore: H6
*Shaft Ø: j6 below 30mm
h6 30mm plus
