Friction bearing type pin-and-block universal joints from Ruland are designed for applications with moderate-to-high-torque requirements in a wide variety of industries. Also called cardan joints or pin-and-block universal joints, they are manufactured from alloy steel for high strength or stainless steel for better corrosion resistance. They are comprised of precision machined, selectively heat-treated and ground components (yokes, pins and blocks) to maximize performance and service life. Single plain bearing universal joints are best suited for space constrained applications and are capable of angular misalignment up to 45°, significantly more than commodity style single u-joints. Double u-joints are better suited for applications with a wide distance between shafts or requiring angular misalignment up to 90°.

Ruland friction universal joints are available in OD sizes ranging from 3/8” to 4” in bore sizes ranging from 3/16” to 2” or 5mm to 35mm. They can have finished bores with or without keyways or machinable bores allowing the user to make custom sizes or geometries. All bore configurations can include a set screw.

Stainless steel (AISI 304)
To DIN 808, maximum bending angle 45° per joint.
Single universal joints are used where shafts are off-set towards each other.
Product variations available on request, for square bores change the suffix to SQ for square bores or HX for hex bores.
