Ruland MQCL-16-A, 16mm Quick Clamping Shaft Collar, Aluminum, Quick Release, 38mm OD, 10mm Width


Ruland MQCL-16-A is a quick clamping shaft collar with 16mm bore, 38mm OD, and 10mm width. No tools are required to install or remove allowing for quick installations and adjustments while reducing downtime. It is designed for light duty stationary or low rotating applications where frequent change outs of items including media, guide rails, or other setup fixturing is required. MQCL-16-A has an integral handle that can be actuated using finger power only for easy postioning adjustments. The screw can be adjusted to be compatible with wider shaft tolerances and provide a range of axial holding power. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. MQCL-16-A is machined from bar stock that is sourced exclusively from North American mills. It is RoHS2 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Product Notes

Note 1

Increasing or decreasing screw seating torque increases or decreases the axial load. Increasing torque will make it more difficult to open the handle.

Note 2

The minimum and maximum axial load data are typical values under certain test conditions and are not a guarantee of average values nor a guarantee of maximum or minimum values under all conditions. Thrust values shown are FAILURE MODE. They are shown solely for the reader to utilize appropriate testing equipment to make his/her own evaluation, and are not intended by Ruland Manufacturing Company, Inc., as warranties, either express or implied, of fitness for a given purpose.
