Slideways' support structures and guides for plastic belts, which can be configured into new and existing FDA/USDA-compliant conveyors systems and process equipment, are made from UHMW or HT-UHMW to create a low-friction and high-wear, water-resistant surface. The modular conveyor supports and guides can be made from several FDA/USDA-compliant thermoplastics and are suitable for applications requiring frequent washdown. Available in a range of sizes, the supports can be designed to work with plastic modular belts from 3.5-in. to 72-in. wide and multiple links or lanes, urethane round belts, flat belts and other types.
