The drives are completely enclosed and sealed inside a steel shell to expel water, dust, grit, chemicals, grease, and oil. The steel shell also guards against the contamination of food, electrical components, plastics, and other materials.
Because the drive unit and bearings mount within the protective shell, the belt drive takes up less room than a conventional drive and runs quieter. The drives are up to 97% efficient, save space, and lower maintenance costs associated with chains, V-belts, couplings, bearings, support structure, and special guards. The low-maintenance design needs only an oil change every 10,000 hr or about once every 5 yr. The 80S and 113S models are lubricated for life.
The belt drives come in diameter sizes 80, 113, 138, 165, and 216 mm, in single-phase 115 or 230 Vac, and three-phase 230/400, 230/460 or 575 Vac, 50/60Hz.
