As we already mentioned in previous blog posts RINGFEDER® Couplings not only play an important role in heavy-duty equipment like cranes and hoists or pumps and compressors. But also our couplings can make or break applications requiring advanced, precision motion control—like surgical robots, medical device manufacturing, medical imaging, lab automation, semiconductor equipment, and industrial robots.

Keyways aren’t the only way to couple heavy-duty motor and gearbox shafts. In fact, keyways aren’t even the best way when you consider the alignment and installation difficulties you’ll encounter when installing keyed shaft couplings that may weigh thousands of pounds. A better alternative is to use couplings that employ a mechanical shrink fit around the shafts.

Bending stress, torque shock, natural frequency and resonance: all the machinery elements in drive systems – i.e. above all axes, shafts, bearings and couplings – must withstand such strains. The coupling plays a prominent system-influencing role which it continues to fulfill better and better due to advanced development.
