Neoprene or Polyurethane Mini-Pitch Timing Belts

Product Announcement from Stock Drive Products & Sterling Instrument - SDP/SI

Hicksville, NY -- An expanded line of Mini-Pitch Timing Belts from Stock Drive Products / Sterling Instrument were designed for light-duty power transmission synchronization, wherever space is limited. With twice the horsepower rating, these belts have a greater number of teeth engaged on the pulleys at all times and therefore larger transmission ratios can be obtained. 

SDP/SI offers these belts as the A 6Z16, A 6Z16M series in Neoprene and also as the A 6G16, A 6G16M, A 6B16, A 6B16M series in Polyurethane. The Neoprene or Polyurethane material is molded around fiberglass helically wound cords. These cords are what gives these belts their unusual strength. 

The teeth of the Neoprene belt are faced with extra durable wear resistant nylon fabric that eliminates the need for lubrication. Circular pitch is not affected, because the belt is designed to locate the pitch line of the drive outside the outer diameter. This virtually eliminates vibration and backlash while ensuring constant angular velocity.
