Portec SG Belt Power Curves

TECHNICAL SPECIFICATIONS

This is only a small example of the model sizes available from Portec. There are 4 standard family sizes of Portec Belt Power Curves based upon the outside conveying radius (C) and a range of conveying widths (F). Any conveying width within the available range and having one of the 3 standard outside conveying radii would be considered a standard model. While Portec frequently designs and builds special radius belt curves, the standard models represent the best value and shortest production lead-time.

*End roll diameter at conveying centerline including belt thickness of 2.9 mm.
Notes: Conveying width (F) is equivalent to "between sideguard" (BSG) width or "between frame" (BF) width. The exposed belt width is approximately 12 mm narrower than the nominal conveying width (F).
The outside radius frame, chain cover and both sideguards extend 9.5 mm past the true angle at both ends of the conveyor. The inside radius frame length matches the true angle.

Application Specials
Portec Flomaster can design and build the Belt Power Curve to meet your special application requirements. Special radius and food grade stainless steel designs are just a few of the many possible specials that Flomaster will do to meet your needs. Portec belt curves are available in a wide range of angles up to 350 degrees.
