This automatic sliding motor base maintains belt tension
The Browning Tenso-set Series 600 horizontal sliding motor base (photo) automatically maintains belt tension for extended periods of time and also allows for very quick belt changes. This device reduces the frequency of re-tensioning services and helps maintain efficiency by preventing belt slippage. The Series 600 operates like a standard motor base, utilizing a jackscrew to adjust and hold tension on the belt. However, the new design includes a coil spring inside the screw housing that pushes against the carriage to maintain tension as the belt wears or seats itself further into the sheave groove. Featuring heavy steel construction, this motor base is sized to fit National Electrical Manufactuers’ Association (NEMA) frame sizes 56 and 286, but custom sizes can be produced for specific applications. — Emerson Industrial Automation, St. Louis, Mo.
