Ruland Flexible Coupler 12.7 mm OD, 4 mm Bore, Set Screw Style Aluminium, 5.6 mm Hub Length MOST13-4-A

Ruland MOST13-4-A Flexible Coupler features a 12.7 mm outside diameter and a 4 mm bore with a 5.6 mm hub length, made from anodised aluminium. This set screw style flexible coupling is designed to accommodate small axial and angular misalignments, making it ideal for motion control and light industrial applications.

The coupling is built with high-quality black anodised aluminium hubs and interchangeable centre discs manufactured from acetal or nylon. This unique three-piece design - two hubs linked by a torque disc - offers excellent protection against torque overloads by allowing the centre disc to break cleanly in overload conditions, acting as a torque limiter.

The set screw hubs are secured onto shafts with one set screw each for diameters 13 mm and 19 mm, ensuring a secure fit. The coupling can operate at speeds up to 4500 rpm, suitable for various mechanical power transmission applications.

This coupling complies with RoHS and REACH environmental standards and is manufactured in the United States, assuring reliable industrial quality. It is especially useful in scenarios requiring controlled torque transmission and protection of sensitive equipment from damage due to overload.

Manufactured from black anodised aluminium for corrosion resistance and durability. Supports angular misalignment up to 0.5°, parallel misalignment of 0.1 mm, and axial misalignment of 0.1 mm. Finished bore without keyway provides precise shaft fitting and easier installation.

Includes two hubs and one torque disc required per assembly. Compliant with international standards including RoHS and REACH.

This flexible coupling is perfect for industrial, laboratory, manufacturing, and motion control equipment. The precision and durable materials deliver reliable performance and extended service life.
