D Type Universal Joints incorporate a standard pin and block design, and are ideal for applications with angles up to 25° and speeds of up to 1,750 RPM. Boot retaining grooves are standard.

For optimal wear and extended life, lubrication and boots are required. (Boots are available for purchase separately.)
