Precision Shaft Collar

The Ruland QCL-22-A is a one-piece aluminium shaft collar designed for inch-based round shafts measuring 1-3/8 inches. It uses a quick-clamp mechanism with a stainless steel screw to secure components without marring the shaft surface. The collar is manufactured from 6061 grade aluminium for a balance of strength and corrosion resistance.

Build Integration

This collar fits directly onto a 1-3/8 inch round bore and requires no keyway or threaded preparation on the shaft. Its 19/32 inch width and 2 15/16 inch outside diameter provide a compact clamping footprint. The quick-clamp lever centred 1.47 inches from the bore allows rapid adjustment or removal during assembly and maintenance.

Target User

Engineers and maintenance teams needing a reusable, non-marring collar for light- to medium-duty power transmission setups will find this suitable. Buyers requiring a keyway, a threaded bore, or a steel collar for higher torque loads should look at alternative designs. The product carries a California Proposition 65 warning for listed chemicals.

Questions about this item

Will the 1-3/8 in bore slip under continuous torque?

The 19/32 in wide 6061 aluminum collar uses a stainless steel screw to clamp the shaft, so holding power depends on screw torque and shaft finish.

Does the quick-clamp lever get hot or vibrate loose during all-day operation?

The 1-piece aluminum body and stainless screw share the load; the lever sits 1.47 in from center and adds no measurable heat or noise.

What shaft diameter and tolerance are required for the 1-3/8 in bore to grip properly?

A round 1-3/8 in shaft with standard inch tolerances is needed; the collar has no keyway or threads and clamps directly on the surface.
