Ruland now develops and manufactures quick-clamping shaft collars and a European patent has been obtained for the design.

The new collars allow for quick adjustments and do not require tools.

They are suitable for printing, packaging, medical, machine vision or semi-conductor manufacturing equipment to retain frequently adjusted items such as rolls of media, guide rails or other setup fixturing or where the need for tools is not practical.

Quick-clamping shaft collars are said to be easily installed.

The collars slide on the shaft smoothly.

They have easy finger access to the handle that allows them to be removed or positioned without tools.

The handle can be locked, fixing the collar in place.

When installed, the handle is flush with the outside diameter, which makes them suitable for rotating and stationary applications.

The design features a tension-adjustment screw that makes the collar compatible to wide shaft tolerances and to adjust the axial holding power on the shaft.

The collars work well on split hubs as well as on solid shafts.

They can be modified by mounting holes to allow them to face-mount other components to the shaft.

Quick-clamping collars are made from aluminium for light weight and low inertia and have an anodised finish.

The hardware on the collars is made from stainless steel, which makes them suitable for wash-down applications, medical applications and certain food applications.

Quick-clamping shaft collars are available with bore sizes from 5/16in to 1 1/2in or 8mm to 35mm.

Ruland shaft collars are also available in one- and two-piece clamp-style designs and a set-screw design.

They are manufactured in a variety of materials including 316 stainless steel, 303 stainless steel, RoHS-compliant yellow zinc plating, high-strength aluminium with an anodised finish, black oxide carbon steel and engineered plastic.

Shaft collars are part of Ruland's complete product line, which also includes rigid couplings with precision-honed bores and five types of zero-backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, curved jaw couplings and miniature disc couplings.
