Product Description

Ruland MWS20-5-5-SS stainless steel flexible coupler is engineered for mechanical power transmission requiring precision and reliability. The MW series features a torsionally rigid, one-piece construction eliminating mechanical joints and potential failure points, ensuring zero backlash during operation.

Designed for operating speeds up to 6000 rpm and torque capacities of 1.3 Nm, this coupling accommodates up to 3 degrees of angular misalignment, as well as parallel and axial shaft misalignments, making it ideal for applications demanding precise alignment without compromising rigidity.

Constructed from high-quality stainless steel, the coupling resists corrosion and operates effectively within a broad temperature range from -40°C to 176°C, ensuring durability in harsh industrial conditions.

Installation is facilitated by screw style fixing with M3 screws staggered at 120 degrees, providing secure shaft attachment. The 20 mm outside diameter and 20 mm length enable compact fitment within limited space machinery.

Typical applications include use with encoders, stepper motors, robotics, servo systems, pumps, valves, and fans across various industrial, laboratory, and manufacturing sectors. Its design supports both high and low speed reversible operation without the need for lubrication.

Durable stainless steel material construction. Torsionally rigid one-piece design for zero backlash. Supports angular, parallel, and axial misalignments. Maximum speed rating of 6000 rpm with 1.3 Nm torque. Screw style fixing with M3 screws for secure assembly.

Operates over wide temperature range (-40°C to 176°C). Suitable for industrial automation and power transmission needs.

This flexible coupling belongs to the MW series, made in the United States, complying with RoHS3, REACH, and DIN 912 12.9 standards. Explore more in EnvMart’s Mechanical Power Transmission and Flexible Coupler categories.
