The Ruland Four beam coupling is expertly designed to provide precision connectivity in high-speed applications. It features robust construction from a single piece of 7075 aluminum, ensuring durability while maintaining a lightweight profile. Designed for zero backlash, this coupling effectively reduces vibration, making it ideal for dynamic environments where performance is crucial. The coupling's unique spiral cut design enhances torque capacity and reduces windup, providing greater reliability under varying operational conditions. With stringent manufacturing processes followed at the Marlborough, MA facility, you can trust this component to perform consistently while meeting North American quality standards. Its compact dimensions allow for seamless interchangeability with single beam couplings, making it a versatile choice for engineers and technicians alike.
Machined from high-strength 7075 aluminum for enhanced longevity
Zero-backlash design ensures precise motion transfer
Engineered for a maximum speed of 6,000 RPM
Ideal for scenarios requiring balanced performance and minimal vibration
Four beam construction improves torque capacity over traditional designs
