High-Precision L-Type Jaw Couplings for Zero-Backlash Servo Transmission

Our L-type three-jaw flexible couplings are engineered for high-performance motion control applications. By combining high-strength ductile iron hubs with a precision-molded NBR rubber spider, we deliver a coupling solution that ensures zero backlash, high torque capacity, and exceptional vibration damping.

Core Performance Advantages

• Zero Backlash Precision: Designed specifically for Servo Motors, providing accurate positioning and zero-play performance.

• High-Strength Ductile Iron: Hubs are crafted from ductile iron, offering superior toughness, wear resistance, and shock absorption compared to standard gray iron.

• H7 Precision Bore: All couplings feature an H7 tolerance bore for a perfect shaft fit, ensuring concentricity even at speeds up to 6000 RPM.

• Premium NBR Spider: The NBR rubber insert provides excellent oil resistance, anti-aging properties, and the ability to absorb significant power shocks.

• Maintenance-Free Design: Self-lubricating material properties and robust construction ensure a long, maintenance-free service life.

• Flexible Misalignment Compensation: Accommodates radial deviations up to 0.3mm, angular eccentricity up to 1°, and axial shifts of +0.5mm.
