Ruland clamp style four beam coupling
Ruland PCMR19-3-3-SS is a clamp style four beam coupling with 3mm x 3mm bores, 19.1mm OD, and 22.9mm length. It is machined from a single piece of material and features two sets of two spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single beam couplings. PCMR19-3-3-SS is zero-backlash […]
Ruland aluminum MBCK33-14-8-A bellows coupling
Ruland MBCK33-14-8-A is a clamp bellows coupling with 14mm x 8mm bores, 33.3mm OD, 42.9mm length, and 5mm x 2mm keyways. It is zero-backlash and has a balanced design for reduced vibration at high speeds. MBCK33-14-8-A is comprised of two anodized aluminum hubs and a stainless steel bellows. The bellows are able to flex while […]
New from Ruland: star knobs and adjustable clamping handles
Ruland has expanded its line of adjustable components to include star knobs and adjustable clamping handles. This expansion gives designers a wider variety of standard in-stock components to choose from when designing machines where quick installation, adjustment, and removal is desired without the use of tools such as those found in packaging, printing, semiconductor, and […]
New from Ruland: slit couplings
Ruland Manufacturing and Reliance Precision have agreed to cooperate by offering Reliance designed and manufactured slit couplings through Ruland’s eCommerce platform and extensive worldwide distribution network. Ruland will stock and bore to size a wide selection of slit couplings in its Marlborough, MA location. The addition of slit couplings gives Ruland a more complete zero-backlash […]
Ruland shaft collars for medical analysis equipment
Ruland manufactures shaft collars from carefully specified raw materials with fine finishes, high holding power, and precise face to bore perpendicularity, making them suitable for medical analysis equipment. Clamp-style shaft collars are commonly used for guiding, spacing, stopping, and component alignment. Medical analysis equipment manufacturers benefit from the tightly controlled face to bore perpendicularity of […]
New coupling technologies offer more support for encoder requirements and washdown settings
The location of mechanical couplings — connecting rotating shafts powered by electric motors and fairly close to the loads being moved or manipulated — makes it an ideal place to optimize the performance of machine axes. No wonder that our 2020 Design World Trends survey of industry experts indicates an uptick in innovation related to […]

Ruland is now selling universal joints. They are available in single and double configurations and allow for angular misalignment up to 90°. Friction bearing type pin-and-block universal joints from Ruland are designed for applications with moderate-to-high-torque requirements in a wide variety of industries. Pin-and-block universal joints are manufactured from alloy steel for high strength or […]
The eight best ways to wreck your coupling driven system
Keeping a servo-driven system running at peak efficiency is no simple feat. Misunderstanding performance criteria such as misalignment, torque, or RPM can be all it takes to cause a critical failure. The following are the eight best ways to consistently sabotage or damage your coupling driven system (and how to avoid them in the future). […]
