Ruland Stainless Steel Flexible Shaft Coupler 20 mm OD 4 mm Bore Size, 20 mm Length, Screw Style MWS20-4-4-SS

Ruland MWS20-4-4-SS is a stainless steel flexible shaft coupler engineered for applications requiring precise alignment and high speed. With a screw style fixing, it ensures secure attachment to shafts while accommodating minor misalignments, enhancing operational reliability in demanding mechanical power transmission systems.

This coupling has a 20 mm outside diameter, is 20 mm in length, and accepts 4 mm bore sizes on both shafts. It is designed to withstand speeds up to 6000 rpm with a torque rating of 1.3 Nm, making it suitable for medium-duty industrial applications.

The one-piece torsionally rigid design eliminates backlash and potential failure points associated with multi-piece couplings. Its stainless steel construction ensures corrosion resistance and durability across a wide operating temperature range of -40°C to 176°C.

This coupling supports misalignment allowances of 3 degrees angular, 0.2 mm parallel, and 0.12 mm axial, providing flexibility in installation and operation without compromising performance. It complies with important industry standards such as RoHS3, REACH, and DIN 912 12.9, ensuring quality and environmental safety.

Typical industrial applications include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans where precise power transmission and reliability are critical.

Constructed from stainless steel with screw style fixing for durability and secure mounting. Features a 20 mm outside diameter, 20 mm length, and 4 mm bore sizes on both sides. Capable of handling up to 6000 rpm maximum speed and 1.3 Nm torque rating.

Allows up to 3 degrees angular misalignment and 0.12 mm axial misalignment, supporting flexible shaft connections.
