Ruland Manufacturing

Ruland Manufacturing QCL-46-A Shaft Collar 2-7/8 in Aluminum

SKU CH-FM0E-081AA

One-piece aluminium shaft collar with quick-clamp lever for 2-7/8 in round bores

  • Quick-clamp lever allows fast repositioning without tools
  • 6061 aluminium body resists corrosion while staying lightweight
  • Stainless-steel screw maintains clamping force in harsh environments
  • Black anodised finish adds surface hardness and wear resistance
  • 38 in lever height gives strong mechanical advantage for secure grip

Quick-Clamp Shaft Collar

The Ruland Manufacturing QCL-46-A is a one-piece quick-clamp shaft collar made from black anodized 6061 aluminum. It fits a 2-7/8 inch round bore and uses a stainless steel screw for secure locking on precision shafts.

Clamping Limits

The single-piece design relies on the screw's holding force to maintain position under axial loads. Aluminum 6061 provides moderate strength but lower clamping torque capacity than steel equivalents, limiting use in high-vibration or heavy-duty power transmission applications.

Installation Notes

The quick-clamp lever allows tool-free adjustment and rapid repositioning along the shaft. Over-tightening the stainless steel screw can strip threads or deform the aluminum bore, so apply only enough force to prevent slippage.

Questions about this item

Which bore size should I choose for a 2-7/8 in shaft?

The QCL-46-A has a 2 7/8 in bore diameter that matches that shaft size exactly.

What does the 2.38 in centre-to-lever-top measurement mean when the collar is installed?

It shows how far the quick-release lever sits above the shaft centreline, so you can check clearance inside the machine.

How does the 1-piece quick-clamp design affect holding power compared to a two-piece split collar?

The single-piece aluminium body with stainless-steel screw clamps evenly around the full circumference, giving uniform grip without a split gap.
