Lovejoy 37786 L050 Solid Jaw Coupling Urethane Elastomer 1.07″ OD

Description

Product Overview

The Lovejoy 37786 L050 solid jaw coupling is engineered for demanding industrial applications where precision, durability, and flexibility intersect. Constructed with a high‑grade urethane elastomer spider, the coupling absorbs shock loads and mitigates vibration, extending the life of connected equipment. The four‑prong solid design locks securely onto the shaft, preventing slippage while allowing up to 39 in‑lbs of nominal torque transmission. With an outer diameter of 1.07 inches and an elastomer length of 0.42 inches, this coupling fits a wide range of standard shafts and offers a nominal torque rating that balances strength with compliance. The compact package dimensions (3 × 2.3 × 0.1 inches) and lightweight construction (8 oz) make it easy to install and handle, while the robust material composition ensures resistance to wear, chemicals, and temperature variations common in industrial environments.

Usage

This flexible coupling is ideal for power transmission systems in manufacturing, material handling, and automation equipment. It excels in applications where shaft misalignment—whether angular, parallel, or axial—must be accommodated without sacrificing torque capacity. Typical use cases include conveyor drives, pump assemblies, gearboxes, and robotic joints where smooth operation and reduced maintenance are critical. The urethane spider dampens sudden load spikes, protecting downstream components such as bearings and seals. Engineers and maintenance technicians appreciate the straightforward installation: the coupling mates directly with Lovejoy L‑type jaw style hubs (sold separately), requiring only basic hand tools and minimal alignment effort. Its performance is validated by a 4.6‑star rating from 32 verified customers, reflecting reliability in real‑world industrial settings.

FAQ

What shaft sizes are compatible with this coupling?

The coupling is designed for a 1.07‑inch outer diameter shaft. It works with standard Lovejoy L‑type jaw hubs, which are sold separately, and can accommodate a range of shaft diameters within the L‑type series.

Can the coupling handle angular misalignment?

Yes. The flexible urethane spider allows for angular, parallel, and axial misalignment, making it suitable for applications where perfect alignment is difficult to achieve.

Is the urethane material resistant to chemicals?

The urethane elastomer is formulated to resist common industrial chemicals, oils, and coolants, providing reliable performance in harsh environments.

What is the maximum torque rating?

The nominal torque rating for this model is 39 in‑lbs, which balances flexibility with sufficient strength for most medium‑load industrial applications.

How do I install the coupling?

Installation requires aligning the coupling’s jaw faces with the corresponding hub faces, inserting the elastomer spider, and tightening the set screws to the recommended torque. Detailed step‑by‑step instructions are included in the product manual.
