The 135 has a special 3 ply highly cross rigid construction designed for SFMB (Surface Finishing Machine Belt) applications. The belt features a high friction, non-marking, oil resistant cover and a low friction bottom fabric suitable for all sanding systems. Developed for use on machines finishing wood, metal and composites. This belt is designed to lay flat and will not curl on the edges due to the special monofilament carcass. Also a very good belt for materials handling and wood products applications and where a non-marking oil resistant belt is required. Excellent for use in folding rail applications in corrugated box plants.
