The Ruland Four beam coupling is designed for precision and reliability, making it an ideal choice for applications requiring high torque and low backlash. Made from robust 303 stainless steel, this coupling is engineered to withstand high-speed operations of up to 6,000 RPM. Its zero-backlash design ensures smooth and efficient performance, reducing vibrations even under dynamic conditions. The unique spiral cut design enhances torque capacity and minimizes wind-up, setting it apart from single beam couplings. With consistent sourcing from North American mills and strict manufacturing standards, this coupling guarantees quality and durability for various mechanical systems.

Crafted from high-quality stainless steel for durability

Zero-backlash design enhances operational precision

Balanced structure reduces vibration during high-speed use

Machined from a single piece for superior strength
