PRODUCT SPECIFICATIONS

Ruland UD8-4-4-F is a double cardan friction bearing universal joint with 0.2500" x 0.2500" bores, 0.495" OD, and 2.813" length. It is ideal for applications with wide distances between shafts and can accommodate all forms of misalignment. This plain bearing double universal joint is comprised of pins and blocks that are precision machined, selectively heat treated, and ground for high strength, accuracy, and wear resistance. The combination of these components with precision ground and hardened yoke ears allow for a longer lifespan, increased performance in demanding applications, and greater angular misalignment of up to 90° when compared to commodity style double universal joints. UD8-4-4-F is made from high grade alloy steel for durability and high strength. It can be combined with boot UBOOT8/13-NI-KIT to protect the joints from unwanted contaminants such as dust or water and self lubricate reducing maintenance time. This double cardan universal joint is manufactured in the USA by Belden Universal for strict control of processes.
