Description

About SK Type QD Bushing

SK QD bushing is the medium-duty type you will meet most often on smaller plant drives - conveyor take-ups, fan and blower shafts, pump drives and light agricultural machinery. It is a compact three-bolt design that still delivers a firm grip: 180 in-lb wrench torque on 5/16-18 cap screws, above the smaller SDS/SH class at the same 1/2-inch minimum bore.


The SK type QD bushing's stock bores start at 1/2 inch (12 mm) and run up to about 2-1/8 inches; inch keyways are standard, metric bores and keyways on request.


Replacing an SK bushing and only know the hub letter or an old part number? Send it over - we will match taper, bolt circle, and cap screws before you commit.
