Ruland Aluminium Set Screw Style Flexible Coupler 12.7 mm OD 6 mm Bore 5.6 mm Length MOST13-6-A

Ruland MOST13-6-A is a high-quality aluminium Oldham style flexible coupler with set screw style hubs. It features a 12.7 mm outside diameter and a 6 mm bore diameter finished without keyway, combined with a 5.6 mm hub length for compact shaft coupling. Designed for applications requiring reliable torque transmission while allowing small misalignments, this coupler suits light industrial machinery, motion control systems, and automation equipment.

The coupler can operate at speeds up to 4500 rpm. It accommodates angular misalignment of 0.5°, parallel misalignment of 0.1 mm, and axial misalignment of 0.1 mm, helping protect connected components from shaft misalignment stresses.

Constructed from anodised aluminium, the set screw hubs allow secure and easy shaft attachment, with set screws sized and positioned according to hub diameter ensuring firm grip. The absence of keyway offers a finished bore for exact fits. These couplings meet rigorous REACH and RoHS compliance requirements.

Oldham couplers are unique three-piece assemblies comprising two hubs and a central torque disc allowing for torque overload protection by clean disc breakage. This product forms part of an assembly requiring 2 hubs and 1 torque disc for full coupling function.

Lightweight anodised aluminium construction ensures durability and corrosion resistance. Set screw style hubs provide ease of installation and solid shaft engagement. Supports small angular, axial, and parallel misalignments protecting machinery.

Speed rating up to 4500 rpm suitable for various industrial and motion control applications. Complies with REACH and RoHS material standards for environmental safety. Manufactured in the USA adhering to strict quality controls and precision engineering.

Designed for use with two hubs and a torque disc for complete Oldham coupling assembly. Ideal for servo and stepper motor driven applications requiring accurate torque transfer. Finished bore without keyway for consistent shaft fitting.

This product is a precise, reliable Flexible Coupler solution extensively used in mechanical power transmission and motion control across diverse industrial sectors including manufacturing, automation, and laboratory equipment.
