Lightweight SUPER-PLAST® Universal Joints

Product Announcement from Stock Drive Products & Sterling Instrument - SDP/SI

SUPER-PLAST® molded universal joints offer the best of both worlds: the economy of plastic, and the fastening characteristics of metal-to-metal contact. In addition, they feature lower inertia, greater torsional strength and higher strength-to-weight ratio than all-metal couplings of similar size. Developed for a wide variety of instrumentation applications, these joints have thick-walled molded plastic hubs for a lightweight, durable and economical design.

These joints are available (Inch & Metric) single or double jointed, with the option of molded or brass slide extensions. All styles are available in inch and metric sizes. All SDP molded universal joints can operate at temperatures up to 180°F (85°C). Maximum angular displacement is 45°, and maximum torque rating is 60 in • lbf.
