The Ruland Clamp style four beam coupling is designed to deliver exceptional performance in precision motion control applications. Machined from a solid piece of 7075 aluminum, this coupling balances high torque capacity with minimal windup, making it ideal for a wide range of industrial uses. The unique four beam design allows for zero-backlash operation, ensuring smooth engagement and disengagement with minimal vibration, even at high speeds up to 6,000 RPM. This coupling is engineered to meet and exceed stringent torque capabilities, providing reliability that is essential for critical applications. With a lightweight build and robust construction, it supports maximum shaft penetration and is compliant with RoHS3 and REACH standards, making it a responsible choice for modern manufacturing.

Zero-backlash design enhances precision and reduces play
Balanced construction minimizes vibration during operation
Manufactured from high-grade 7075 aluminum for strength and durability
Internal structure designed for improved torque capacity
Complies with international standards for safety and reliability
