Ruland Stainless Steel Flexible Coupler 15 mm Outside Diameter, 4 mm Bore Size, 20 mm Length, Screw Style MWS15-4-4-SS

Ruland MWS15-4-4-SS Stainless Steel Flexible Coupler is engineered for demanding mechanical power transmission applications where high speeds and precise misalignment compensation are critical. Constructed from robust stainless steel as a one-piece torsionally rigid unit, this coupling eliminates mechanical joints and minimizes failure points.

This coupling supports speeds up to 6000 rpm and delivers a torque capacity of 0.85 Nm while allowing angular misalignment of up to 3°, parallel misalignment of 0.2 mm, and axial misalignment of 0.12 mm. Operating reliably in temperatures from -40°C to 176°C, it is ideal for environments with temperature variations and limited lubrication conditions.

The screw style design uses M3 grub screws staggered at 120° for secure shaft attachment. This coupling is widely used in precision applications including encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans.

Compliant with DIN 912 12.9, REACH, and RoHS3 standards, the MWS15-4-4-SS series assures environmental and safety compliance. The 15 mm outside diameter and 20 mm length provide compact installation in tight spaces.

Manufactured as one piece stainless steel body to ensure torsional rigidity and zero backlash. Capable of high speed operation with maximum speed rating of 6000 rpm. Accommodates angular, parallel, and axial misalignments to protect connected equipment.

Suitable for industrial, robotics, automation, and laboratory applications. Compliant with DIN 912 12.9 fastener standards, REACH, and RoHS3 directives. Stainless steel construction ensures corrosion resistance and durability.

Includes M3 screw fixing style for reliable shaft holding without slip.

This coupling is a critical component in mechanical power transmission systems requiring precise alignment and resilient operation under dynamic conditions. Explore more products in the Mechanical Power Transmission Coupler category at EnvMart for complementary components and accessories.
