Industrial MA700312 Rubber Serrated Roller Assembly

SMI MA700312 Rubber Serrated Roller Assembly is an industrial‑grade roller unit built around a rubber serrated surface, measuring 43¼ inches in length and driven by a 25 mm shaft (approximately 1.10 m long with a 0.98 in diameter shaft). The MA700312 model designation identifies this specific component within SMI’s catalog of conveyor and roller assemblies. As a rubber serrated roller, the textured surface provides a defined contact area that influences grip and load distribution along a conveyor span, while the 25 mm shaft diameter indicates the mounting bore size for rotation. Being described as an assembly, it is supplied as a complete unit designed to be mounted into compatible conveyor frames, helping simplify installation. The notable 43.25-inch length offers extended coverage across the belt path, which can affect how many rollers are required in longer runs. This description highlights the core, verifiable characteristics: manufacturer SMI, model MA700312, rubber serrated surface, 43¼ inches in length, and a 25 mm shaft diameter.
