Ruland 19 mm Outside Diameter 6.35 mm Bore Finished with No Keyway Clamp Style Aluminium Flexible Coupler OCT12-4-A

Ruland OCT12-4-A clamp style flexible coupler offers a precisely engineered mechanical connection solution with a 19 mm outside diameter and 6.35 mm bore finished with no keyway. Manufactured from lightweight anodised aluminium, it provides excellent corrosion resistance and durability in demanding industrial environments.

This Oldham coupling design consists of two hubs and a replaceable center torque disc, allowing some axial and angular shaft misalignment while protecting connected machinery by acting as a torque limiter. It is ideal for light industrial, motion control, and servo motor applications with rotational speeds up to 4500 rpm.

The clamp style hubs secure shafts using set screws - one per end on 13 mm and 19 mm hubs - ensuring a reliable fit. The coupler electrodes can tolerate up to 0.5° angular, 0.2 mm parallel, and 0.1 mm axial misalignment.

Ruland Flexible Couplers comply with RoHS and REACH environmental standards, highlighting its eco-friendly manufacture and material selection. The product is fabricated in the United States and engineered for robust performance in mechanical power transmission applications.

Lightweight anodised aluminium hubs with replaceable nylon or acetal center discs. Three-piece Oldham coupling accommodates small misalignments to protect machinery. Clamp style securing with one set screw per shaft end on relevant sizes.

Supports maximum rotational speeds of 4500 rpm for dynamic applications. Meets environmental directives RoHS and REACH. Ideal for motion control, light industrial, and servo motor systems. This coupler is part of the comprehensive Ruland power transmission components line and is suitable for engineers seeking reliable and high-precision shaft coupling solutions.
