Universal Joint UJ-0707 7/8in ID High Torque Relubricable Bailey

Description

Product Overview

The Bailey Universal Joint UJ-0707 is engineered as a robust Cardan‑style shaft coupling that meets the rigorous demands of modern power transmission systems. Constructed from high‑strength alloy steel, the joint features a 7/8in inner diameter, a 3/16in keyway, and an overall length of 5in, allowing it to fit a wide range of shafts and equipment. Its design supports up to 90° of angular deflection and operates reliably at speeds of up to 1000 RPM, delivering a consistent torque rating of 800 lb‑in. The assembly incorporates drop‑forged slip yokes that provide precise alignment and reduce side thrust on bearing bushings, while the regreaseable needle bearings enable simple maintenance and extended service life. Weighing only 2.5 pounds, the joint offers a high power‑to‑weight ratio, making it ideal for both stationary machinery and mobile applications where weight and space are at a premium.

Usage

Designed for versatility, the Bailey Universal Joint excels in a variety of industrial, automotive, and commercial environments. In manufacturing plants, it connects motor shafts to conveyor drives, providing smooth power transfer even when shafts are slightly misaligned due to thermal expansion or mounting tolerances. In the automotive sector, the joint is suitable for high‑performance drivetrains, enabling reliable torque transmission to wheels, differentials, and auxiliary equipment such as power steering pumps. Marine and offshore installations benefit from its corrosion‑resistant finish and ability to handle the dynamic loads encountered in wave‑driven generators and pump‑jack assemblies. The joint’s 15% angular displacement capability at peak velocity ensures that equipment can operate without excessive vibration, reducing wear on adjacent components and extending overall system longevity.

Because the joint includes regreaseable needle bearings, maintenance crews can quickly apply fresh grease without disassembly, minimizing downtime. The compact 5in length allows installation in confined spaces where larger couplings would be impractical. Whether used in a high‑speed turbine, a heavy‑duty forklift, or a precision CNC machine, the Bailey Universal Joint delivers consistent performance, making it a trusted choice for engineers who demand reliability and efficiency.

FAQ

What is the maximum angular misalignment the joint can handle?

The UJ‑0707 can accommodate up to 90 degrees of angular deflection, with a recommended operating range of 15% angular displacement at peak speed for optimal performance.

Can the joint be used in high‑temperature environments?

Yes. The alloy steel construction and heat‑treated bearings are rated for continuous operation up to 200 °F (93 °C), making it suitable for most industrial temperature ranges.

How often should the needle bearings be regreased?

We recommend inspecting the bearings every 6 months and applying fresh grease as needed. In high‑duty applications, a quarterly check may be advisable to maintain peak efficiency.

Is the joint compatible with standard shaft sizes?

The 7/8in inner diameter and 3/16in keyway conform to common industry standards, allowing it to mate with a wide variety of shafts and hubs without the need for custom machining.

What warranty does Bailey provide for this product?

Bailey offers a 12‑month limited warranty covering material defects and premature wear when the joint is used according to the provided specifications and maintenance guidelines.
