Flexible Shaft Coupling – Jaw, Clamping Type

Our Flexible Shaft Coupling – Jaw Clamping Type is a high-performance flexible coupling designed to transmit torque while compensating for shaft misalignment. Featuring a robust three-piece design with a durable polyurethane spider (blue elastomer insert), this coupling delivers excellent vibration damping, shock absorption, and reliable power transmission in demanding industrial applications.

The clamping-type hubs provide a strong, backlash-free connection to the shaft without requiring keyways, making installation fast and secure. Precision machined from high-quality aluminum alloy, this coupling ensures outstanding concentricity and balance for smooth, quiet operation at high speeds.

Flexible Shaft Coupling Key Features & Benefits

• Jaw Spider Design The flexible polyurethane spider (insert) effectively absorbs shock, vibration, and minor misalignments (parallel, angular, and axial). Easy to replace when worn — no need to disassemble the entire coupling.
• Clamping Type Hubs Powerful clamping rings with tightening screws ensure a secure, high-torque grip on the shaft. Provides zero-backlash transmission and excellent shaft holding power without damaging the shaft surface.
• High-Quality Materials Precision CNC-machined aluminum alloy hubs for lightweight strength and superior heat dissipation. The blue spider is made of high-grade polyurethane, offering excellent resilience, oil resistance, and temperature stability.
• Zero Backlash & High Precision Designed for accurate motion control with minimal backlash, making it ideal for servo motors, stepper motors, and precision automation systems.
• Easy Installation & Maintenance Split clamping design allows quick assembly and disassembly. No special tools required.
• Wide Temperature Range Reliable performance from -30°C to +80°C (standard spider). Custom spiders available for higher temperatures.
