April 19, 2013 – Ruland Manufacturing Co. Inc. has expanded its quick-clamping shaft collar line to accommodate sizes up to 3 in., and is designed for light-duty stationary or low-RPM applications that require quick-positioning adjustments or frequent set-up changes where the use of tools is not practical. When installed, the handle sits flush with the outside diameter, making them suitable for rotating applications. The design features a tension-adjustment screw, making the collar compatible to shaft tolerances. All Ruland shaft collars, including quick-clamping, have tightly controlled face-to-bore perpendicularity, says the company, for proper component positioning on the shaft and even pressure on interfaced components. Quick-clamping shaft collars are available in bore sizes ranging from 0.25 in. to 3 in. In Canada, Ruland products are available from RotoPrecision Inc.
