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.

Of the wide variety of equipment used by the pharmaceutical industry, vacuum pumps are predominant. They are used in research labs and large-scale production units of bulk drugs, active pharmaceutical ingredients (API) and by intermediates manufacturers. Various pharmaceutical processes, including degassing, vacuum distillation, crystallization, drying, freeze drying and sterilization utilize vacuum pumps. These vacuum pumps ensure high efficiency and low cost of operation by minimizing wear and leakage. The high demands made on vacuum pumps can be optimally fulfilled with the help of RINGFEDER® Locking Assemblies. Read this article to learn how!

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.
