Lovejoy Universal Joint D13B 1-1/4″ Bore Pin & Block – 2.5″ OD, 7″

Description

Product Overview

The Lovejoy D13B universal joint is engineered for demanding industrial applications where reliability, precision, and durability are paramount. Constructed from high‑grade steel, this pin‑and‑block joint delivers exceptional torsional strength while maintaining a compact footprint. The 1‑1/4″ round bore allows for direct installation onto standard shafts without additional machining, reducing downtime and simplifying maintenance. With an outer diameter of 2.5 inches and an overall length of 7 inches, the joint fits into confined spaces while providing a robust connection capable of transmitting power efficiently.

Designed to accommodate up to 25 degrees of angular misalignment, the D13B ensures smooth power transfer even when shafts are not perfectly aligned. Its ability to operate at speeds up to 1,750 RPM makes it suitable for high‑speed machinery, while the temperature range of –30 °F to 212 °F guarantees performance in both cold‑storage and high‑heat environments. The joint’s keyways (1/4″ x 1/8″) and setscrew provide secure fastening, preventing slippage under load.

Usage

This universal joint excels in a variety of industrial settings, including material handling equipment, conveyor systems, mixers, and agricultural machinery. Its robust steel construction makes it ideal for heavy‑duty applications such as gearboxes, pumps, and compressors where consistent torque transmission is critical. The joint’s ability to compensate for shaft separation and angular misalignment reduces wear on adjacent components, extending the overall lifespan of the equipment.

Installation is straightforward: the bored hubs slide onto the shafts, and the setscrew secures the joint in place. This simplicity allows technicians to replace or service the joint quickly, minimizing production interruptions. Whether used in a factory floor, a processing plant, or a field‑deployed system, the D13B delivers reliable performance under a wide range of operating conditions.
