Our high-precision jaw fluid coupler delivers reliable power transmission for a wide range of industrial applications. Designed as a Lovejoy-type coupling, it features a durable aluminum body and a flexible spider made of polyurethane or cast nylon, offering excellent resistance to wear, misalignment, and vibration. This flexible shaft coupling efficiently compensates for angular, parallel, and axial deviations while maintaining smooth torque transmission between connected equipment such as pumps, motors, and compressors.

With a nominal torque range of 5.0–250 N.m and maximum rotational speeds from 4,000 to 10,000 RPM, this coupling is built for high-speed, high-stability operation. The star-type elastic spider ensures outstanding damping performance, reducing noise and protecting machinery from shock loads. Available in silver-white or custom colors, and with optional surface treatments including carburizing, electroplating, and quenching, this Lovejoy-style coupling can be tailored to your specific environmental and operational needs. Ideal for HVAC, automation, packaging, and hydraulic systems.

Description
This jaw fluid coupler is a flexible coupling built to the same standards as Lovejoy couplings, offering reliable performance in fluid power and general industrial applications. Its jaw and spider design enables smooth transmission of torque while accommodating misalignments that commonly occur in motor-pump or motor-fan systems. The aluminum construction minimizes weight and inertia, making it suitable for high-cycle and high-speed uses. The spider, available in multiple hardness levels (PU or nylon), can be selected based on application requirements—whether for high flexibility, oil resistance, or high-temperature tolerance. Easy to install and maintain, this coupling is a cost-effective, high-value solution for improving drive system life and performance.
