This Lovejoy D Type steel single pin-and-block universal joint with round bored hubs is designed to connect two rotating shafts at angles up to 25 degrees. This universal joint compensates for angular misalignments and has a single joint configuration for high torsional stiffness and torque capacity. The hubs, center block, and pins are made of steel for strength and durability, and the bored hubs fit onto shafts without the need for machining. Operating temperatures range from -30 to 212 degrees F. For optimal wear and extended life, boots (sold separately) are recommended, and boot retaining grooves are standard on this design. This universal joint provides a uniform speed ratio between driving and driven shafts, and is suitable for applications requiring moderate torque transmission, such as compressors, fans, machine tools, printing presses, and textile machinery. Universal joints (also called U-joints, universal couplings, Cardan joints, Hooke’s joints, or Hardy-Spicer joints) are used to transmit motion and rotational power, or torque, between two shafts that are offset at an angle. Most universal joints consist of two yokes and a middle assembly; the hub end of each yoke att
