The Ruland single beam coupling is designed for high positioning accuracy in precision applications, featuring an Advanced zero-backlash design suitable for high-performance environments.
Machined from a single piece of 7075 aluminium for lightweight and low inertia
Offers enhanced misalignment capabilities over traditional multiple beam couplings
Compatible with metric shaft dimensions, fitting into smaller envelopes than ISR-series
Constructed to exceed DIN 912 12.9 standards for maximum torque capacity
Dynamic torque ratings of up to 1.02 Nm ensure reliability in demanding applications
