Our flex jaw coupling is engineered for high-performance power transmission in precision industrial applications. Designed as a flexible shaft coupler, it features a robust jaw and spider structure with an elastic rubber or nylon spider element, effectively compensating for angular, parallel, and axial misalignments. Made from high-grade aluminum alloy or steel, this shaft coupling ensures lightweight yet durable operation, ideal for high-speed systems requiring minimal inertia and vibration.

With a nominal torque range of 5.0–250 N.m and maximum RPM up to 10,000, this coupling delivers smooth, reliable power transfer while reducing noise and wear on connected equipment. It is widely used in packaging, automation, CNC machinery, and servo systems. Customization options include surface treatments such as carburizing, electroplating, or quenching, along with color and material adaptations. Easy to install and maintenance-free, our flex jaw coupling guarantees long-term stability and efficiency for your industrial drives.

Features

• High-Strength Materials: Aluminum alloy or steel body for durability and reduced weight.

• Elastic Spider: Polyurethane (PU) or cast nylon spider for shock absorption and misalignment compensation.

• High-Speed Operation: Supports RPM from 4,000 to 10,000 for dynamic applications.

• Surface Treatments: Options include carburizing, blackening, electroplating, and quenching.

• Customization: Available in different colors, materials, and spider hardness levels.

• Zero Maintenance: No lubrication required for long-term, trouble-free operation.

Description
This flexible jaw coupling is a torsionally rigid yet radially elastic shaft coupler designed to connect two rotating shafts while accommodating misalignment and dampening vibrations. The aluminum alloy construction makes it suitable for applications where weight and precision are critical, such as in robotics, packaging machines, and servo-driven systems. The spider, available in PU or nylon, acts as the flexible element, enabling smooth torque transmission and protecting machinery from unexpected shocks or vibrations. With high-frequency quenching heat treatment and multiple surface finish options, this coupling resists wear, corrosion, and operational fatigue, ensuring reliability across various industrial environments.
