In the 19th and early 20th centuries, flat belt pulleys were widely used in line shafting to transmit power in factories. We are manufacturer, exporter of flat belt pulleys at market leading price. They were also use in mining, farming and logging applications like silo blowers, balers, bucksaws, threshers, sawmills, conveyors for filling corn cribs or haylofts, water pumps (for wells, mines, or swampy farm fields) and electrical generators. Flat belts are still used today, though not nearly as frequently as they were during the line shaft era.
The flat belt is a simple power transmission system that was well suited for its day. In case of wide belts and large pulleys, it is capable of delivering high power at high speeds (500 hp at 10,000 ft/minute or 373 kilowatts at 51 meters per second). However, these wide belts and large pulleys drives are bulky, occupying significant space while requiring high tension resulting to high loads and are not well suited to close-centers applications. For short distance power transmission V-belts have largely replaced flat belts, for longer distance power transmission is typically done without belts at all. Modern factory machines commonly use individual electric motors instead.
