Shaft collars with levers are available from Ruland in one- and two-piece clamp styles in a variety of materials


No tools required: Ruland’s new quick clamping shaft collars with clamping lever R


uland, manufacturer of shaft collars and couplings, now supplies quick clamping shaft collars with


clamping levers. These collars require no tools to install, remove, or reposition. They are significantly faster to adjust than collars with standard hardware, making them ideal for use in applications where frequent set up changes or adjustments are required in industries such as packaging, printing, medical, and food processing.


Construction Quick clamping shaft collars with clamping lever combine a Ruland shaft collar with a metric or imperial bore and an adjustable lever to create an easy to use assembly that can be repositioned without the need for additional tools. Shaft collars are manufactured in one- and two-piece styles allowing designers flexibility to select the style that best fits their application.


How to Operate Once the assembly is complete, users can simply turn the lever until the desired torque is met. For fine positioning adjustments, the lever must be lifted and twisted 40° to lock it in a new position. This feature allows the lever to be used in space constrained applications where 360° motion is not possible. The lever is designed to mate directly with the Ruland shaft collar for proper fit, smooth torquing action, and infinite adjustability. This allows the collar to be rapidly and frequently repositioned in a wide variety of industrial applications.


Common Shaft Collar Uses Quick clamping shaft collars with clamping lever can be used for guiding spacing, stopping, mounting, and component alignment. Since seating torque cannot be precisely controlled they have lower holding power than shaft collars with traditional hardware and are best suited for lighter duty applications. Designers benefit from the tightly controlled face to bore perpendicularity of Ruland shaft collars (TIR ≤ 0.002” or .05mm) which is critical when they are used as a load bearing face or for

component alignment. Ruland identifies this work surface with one or two circular grooves on the face of the shaft collar to assist in installation.


Proprietary processes Ruland manufactures shaft collars from high-strength 2024 aluminum, 1215 lead-free steel with a proprietary black oxide finish, and 303 and 316 stainless steel. Quick clamping shaft collars with clamping levers are available in sizes ranging from 11 mm to 40 mm (7/16 inch to 1-1/2 inches). Shaft collars are manufactured in Ruland’s Marlborough, Massachusetts factory under strict controls using proprietary processes. Levers are sourced from JW Winco and have a stainless steel threaded stud (M4-M6) that is used to replace standard collar hardware. They are available in black for general industrial use or orange for safety. All components in these shaft collars are RoHS3 and REACH compliant.


With this addition, Ruland now offers two styles of


quick clamping shaft collars – with clamping lever and with cam lever. These options give machine designers unmatched flexibility to use standard components when designing a system that requires frequent and/or rapid change-outs. Full product specifications and 3D CAD models are available on ruland.com.
