An expanded series of 55
SUPER-PLAST® molded universal joints confer to designers the best of both worlds: The economy of plastic, plus the positive fastening characteristics of metaI-to-metal contact. In addition, these light-weight u-joints feature lower inertia, greater torsional strength and higher strength-to-weight ratio than do equivalent all-metal couplings.
Developed for a wide variety of instrumentation applications, especially where the starting torque of a drive is too high for conventional all-plastic u-joints, the
SUPER-PLAST® types combine brass inserts within a thick-walled molded plastic hub. This construction leads to a lightweight, durable and economical design.
Four different universal joint types are available including: single, double, plus types with molded slide extensions, and with brass slide extensions. AII are available in inch and metric sizes, and most are available completely molded with metal spiders, or with inserts and metal spiders.
The bodies are made from molded acetal with the spiders and inserts made from nickel plated brass. With these components, using
SUPER-PLAST® designs, you can replace metal components inexpensively, especially for low torque applications. AII SDP molded universal joints can operate at temperatures up to 180° F (85°C).
The molded universal single joints have an angular displacement of up to 45° and are available in lengths ranging from 3/4" to 2-5/64" (19.0 mm to 52.7 mm) for fully molded pieces and 1 -3/64" to 2-41/64" (26.6 mm to 66.9 mm) for those with inserts. O.D.'s range from 1 /4" to 5/8" (6.3 mm to 15.9 mm) for all pieces. Maximum torques for these joints range from 5.0 to 60 Ib.in. (.57 to 6.8 N•m).
The molded universal joints with molded slide extensions have an angular displacement of 90° maximum and can be extended up to 3/4" ( 19 mm) . The maximum torques range from 8 to 14 Ib.in. (0.9 to1.6 N•m) closed and from 5 to 10 Ib.in. (0.5 to 1.1 N•m) open. Typical bore depths for these joints range from .34" to .63" (8.6 mm to 16 mm).
The molded universal joints with brass slide extensions have angular displacements of up to 90° and can be extended up to half the length of their brass tubes. These joints have closed lengths ranging from 3-1/4" to 8" (82.6 mm to 203.2 mm). These telescoping universal joints have typical bore depths ranging from .39" to .86" (9.9 mm to 21.8 mm).
