Product Details

Ruland Coupling

The Ruland bellows coupling has a 51mm OD and 58.7mm length with set screw fastening. This clamp is 20mm x 20mm bore coupling. This is readily accommodated by any combination of axial motion, angular and parallel misalignment. It comprises of two anodized aluminium hubs and stainless steel bellows. This bellow is able to flex while remaining rigid under torsional loads. Its balanced design reduces vibrations at high speed.

Features and Benefits

Zero backlash Black-oiled alloy steel fasteners for strength and corrosion resistance Precision bellows coupling with excellent kinematic properties Maximum speed of 10,000rpm Hardware is metric and tested beyond DIN standard for high torque capabilities Set screw material is alloy steel with black oxide finish Service temperature range from -40°C and 93°C Low inertia coupling Lightweight

Applications

Stepper and servo drives Encoders General purpose light-duty power transmission

Certifications

REACH certification Conflict Minerals compliant DIN 912 12.9 ISO9001:2015
