The Ruland Clamp Double Disc Coupling is designed to meet the rigorous demands of high-speed applications. Fabricated from solid bar stock sourced exclusively from North American mills, this coupling offers exceptional performance with a lightweight and low inertia profile. Its dual anodized aluminium hubs and stainless steel disc springs create a zero-backlash system, ideal for precise positioning in servo-driven environments. Capable of withstanding angular and parallel misalignment, it ensures operational reliability in various industrial settings, from semiconductor production to printing machinery. The coupling's robust architecture is engineered to maintain high torque capabilities while minimising vibration, making it particularly suited for applications that require silent and efficient operation under challenging conditions.

Zero backlash design promotes precise motion control
Low inertia supports fast acceleration and deceleration rates
Anodised aluminium construction enhances durability and corrosion resistance
Able to handle significant misalignment reducing wear on connected shafts
Manufactured with strict quality control for consistent performance
Complies with RoHS3 and REACH standards for safety and environmental responsibility
Utilises high performance stainless steel disc springs for optimal torque ratings
Torsionally rigid design ensures stability during high speed operation
Lightweight profile facilitates ease of installation without sacrificing strength
