Product Description

The spider jaw coupling is a widely used flexible shaft connection solution designed for reliable torque transmission, vibration damping, and precise alignment compensation. As a professional coupling manufacturer in China, Apexcoupling supplies high-quality spider jaw coupling products for global OEM and industrial customers, supporting both standard production and non-standard customization.

This spider jaw coupling adopts a classic jaw and spider structure, combining two aluminium alloy hubs with a high-elastic polyurethane spider. The design ensures zero rotational clearance, making the spider jaw coupling suitable for both positive and negative rotation. It is especially ideal for applications requiring smooth power transmission and protection of connected equipment.

Manufactured from high-strength aluminium alloy, each spider jaw coupling offers excellent strength-to-weight ratio, corrosion resistance, and long service life. The aluminium hubs are precision-machined and surface-treated to ensure dimensional accuracy and stable performance. The internal PU spider provides outstanding abrasion resistance, elasticity, and damping characteristics, enabling the spider jaw coupling to absorb shock loads and reduce vibration during operation.

One key advantage of this spider jaw coupling is its ability to compensate for radial, angular, and axial misalignment. This feature helps extend the service life of motors, gearboxes, and bearings while maintaining stable torque transmission. The detachable structure allows easy installation and maintenance, reducing downtime in industrial environments.

The fastening method uses a clamping screw design, ensuring secure shaft connection and reliable torque transfer. With a rated torque of up to 2000 N·m and a maximum speed of 1000 RPM, this spider jaw coupling is suitable for various medium-to-high load applications. Bore sizes range from 3 mm to 8 mm, and customized bores or keyways can be provided upon request.

This spider jaw coupling is widely used in construction equipment, energy and mining machinery, food and beverage processing lines, manufacturing plants, agricultural machinery, and machine repair workshops. Its resistance to oil, dirt, sand, grease, moisture, solvents, and ozone makes the spider jaw coupling reliable even in harsh operating conditions.

As a direct factory exporter, Apexcoupling offers OEM, ODM, and OBM services for spider jaw coupling projects. Custom materials, dimensions, keyways, and CAD drawings are supported. With strict quality inspection and professional selection support, our spider jaw coupling products help global buyers reduce sourcing risk and improve system reliability.

If you are looking for a stable, durable, and cost-effective spider jaw coupling, Apexcoupling is your trusted manufacturing partner in China.
