About
RL - Long Style
EXPLORE >>
Long style slit couplings have added torque and misalignment capabilities compared to the short styles. They are an alloy, one-piece configuration designed to provide smooth transmission of motion, high torsional stiffness, low bearing loads, and long life. Bore sizes start at 1.5mm with outer diameters as small as 6mm for use in sensitive precision applications. Ruland slit couplings are RoHS3 and REACH compliant.
RS - Short Style
EXPLORE >>
Short style slit couplings are ideal for compact installations. They are a one-piece design made from 7075 aluminum for a long, zero-backlash life. The two sets of identical slits provides the best balance between zero backlash, torsional stiffness and low bearing load. Slit couplings can accommodate parallel misalignment, angular misalignment, and axial motion. Ruland slit couplings are RoHS3 and REACH compliant.
Why Ruland?
- Speeds up to 70,000 RPM with reduced vibrations due to a balanced design.
- Micro-bore sizes start at 1.5mm for sensitive precision scientific and medical systems.
- Reduced bearing loads and enhanced misalignment tolerance. The patented slit design features radiused edges that improve coupling longevity and torsional stiffness.
- Eliminates the performance limitations while being a suitable alternative to:
- Stainless steel beam couplings which have high inertia.
- Aluminum beam couplings which have limited torque and torsional stiffness capabilities.
- Single disc couplings which can not accommodate parallel misalignment.
