Ruland quick-clamping shaft collars require no tools for installation, adjustment or removal, making them a convenient and efficient choice for a variety of packaging equipment and applications. Designers and operators of packaging machines (such as bundlers, cartoners, and wrappers) can benefit from the faster, tool-less adjustment of quick-clamping shaft collars.
Ruland offers two types of quick-clamping shaft collars: collars with cam levers and collars with clamping levers. Those with cam levers have an integral lever that sits flush with the outside diameter and is finger-actuated. The design features a tension-adjustment screw that can be adjusted to tailor axial holding power to application needs.
These collars are one-piece clamp style and require shaft end access to be installed properly. They’re suited for light-duty and low-rpm applications with frequent change-outs of items such as guide rails or other setup fixturing.
Those with a clamping lever feature a Ruland manufactured shaft collar combined with an adjustable clamping lever that replaces standard hardware. The final assembly is a shaft collar with a ratcheting handle that can be easily installed, removed, or repositioned without tools.
They’re offered in one and two-piece clamping styles and with outer diameter flats and holes for easier mounting of other components. They also offer the benefits of traditional shaft collars — such as not marring the shaft, tight controlled face-to-bore perpendicularity (TIR of ≤ .002 inch or 0.05 mm), and a fine burr-free finish — allowing them to be used in a wide variety of packaging applications.
Quick-clamping shaft collars with cam levers are manufactured from 6061 anodized aluminum bodies and 6063 aluminum handles with bore sizes from 1/4- to 3-inches and 6 to 75 mm. The shaft collars with clamping levers are offered in standard materials including 1215 lead-free steel with black oxide or zinc-plated finish, 303 and 316 stainless steel, high strength 2024 aluminum, and engineered plastic.
The lever is sourced from JW Winco and features a zinc-plated handle with a stainless steel threaded stud and internal components.
