Carefully Made Shaft Collars and Couplings

"Ruland Manufacturing Co. Inc. will provide the timely delivery of products which meet or exceed specifications and whose performance and appearance are in accordance with the Company's tradition of continual improvement and high manufacturing standards."

Established in 1937, Ruland focuses on the design and manufacturing of high performing shaft collars and couplings. All products are carefully manufactured in Marlborough, Massachusetts factory under strict controls using proprietary processes.

What's New?


This Ruland bundle combines a one or two-piece shaft collar with a clamping lever to make a quick release shaft collar. Bore sizes range from 3/8” to 1 ½” and 11mm to 40mm. Collars are available in anodized aluminum, plain aluminum, 303 stainless steel, 316 stainless steel, steel, plastic, and zinc.


The patented slit design has radiused edges that reduce stress on the coupling allowing for high misalignment and torsional stiffness with low bearing loads. Ruland stocks and bores to size slit couplings in bore sizes ranging from 1.5mm to 12mm or 1/8” to 3/8”.


Vibration, impact loads, and noise are likely to be important considerations in most environments, and a common way to mitigate these factors is by using vibration isolation mounts and rubber bumpers.


The expanded range of universal joints will be available through Ruland’s eCommerce platform and traditional distribution channels offering customers a variety of ways to purchase.
