Norelem, the French/German company specialized in the production of standard parts, launches a new family, under the ref. 22500, of articles to build 90° worm/gear couplings. The pairs worm/gear are available in several sizes ranging from 17 to 80 mm center to center and various gear ratios for each size. The right hand worms are in surface hardened steel with ground flanks and bores. The bronze gears, thanks to their frictionless property assure smooth transmission and the aluminum-component of bronze is highly recommended against chemical resistance. These couplings are recommended for longlife use at high speed and for high torques. Norelem supplies them, without any limit to the minimun order, normally ready to use and without the need for adjustment. This new range of worm/gear couplings increases the products pallet which offers already more than 30.000 items, distributed in Italy by Sermac.
