Product Description
Ruland OCT16-4-A Clamp Style Oldham Coupler is an aluminium mechanical coupling designed to connect shafts with slight misalignments. Featuring a 25.4 mm outside diameter, 6.35 mm bore diameter finished with no keyway bore, and a hub length of 11.86 mm, this coupling offers robust performance with a maximum speed rating of 4500 rpm.
The clamp style hubs are anodised black aluminium, providing a lightweight yet sturdy structure. The unique three-piece Oldham design consists of two hubs connected via a replaceable centre torque disc made of acetal or nylon, enabling axial, angular, and parallel misalignments to be accommodated, making it suitable for precise motion control systems such as servo and stepper motor applications.
This coupling style improves machinery protection by acting as a torque limiter; the centre discs are engineered to break cleanly under torque overload, preventing damage to connected equipment. The securing mechanism uses set screws on anodised aluminium hubs, with one set screw for 13 mm and 19 mm hubs and two set screws spaced 90° apart on larger hubs.
The product complies with RoHS and REACH directives, ensuring environmental safety. It is manufactured in the United States under stringent quality control for industrial and light manufacturing environments.
Constructed from anodised aluminium hubs for strength and corrosion resistance. Clamp style attachment with set screws for secure shaft coupling. Designed for small angular (0.5°), parallel (0.2 mm), and axial (0.1 mm) misalignments.
Maximum speed capability of 4500 rpm supports high-speed operations. Replaceable centre discs provide torque overload protection by clean breakage. Compliance with RoHS and REACH standards is guaranteed. Suitable for light industrial use, motion control, and servo motor coupling.
Requires two hubs and one torque disc for each full coupling assembly. Manufactured in the United States for reliable industrial quality.
This coupling is ideal for industrial, laboratory, manufacturing, and motion control applications requiring precision and reliable mechanical power transmission.
