SKF’s cogged raw edge (CRE) belts are ideally suited for essentially any industrial application that runs on ISO wedge and classical V-belt pulleys. Manufactured from rugged ethylene propylene diene monomer (EPDM) synthetic rubber, these ISO 4148 compliant CRE belts offer users a host of benefits that drive down input costs and drive up productivity.
“The cornerstone to our tough and reliable CRE belts is the EPDM manufacturing compound,” says product manager, Micaela Willers. “This durable composite provides excellent flexibility and high transverse rigidity across the belt, thus significantly increasing the life of the belt drive. The synthetic rubber gives the belts a long life even when they operate in extreme ambient temperatures that range from -50 to 120°C. These belts have higher power ratings, they wrap better, and they are ultimately more efficient than ever.”
Further extending the lifecycle of the CRE belts are the tension cords, which are manufactured from pre-tensioned, stabilised rubber-impregnated polyester yarn that minimises belt elongation during operation. The design of the belt incorporates an upper support rubber cushion manufactured from fibre-loaded EPDM compound. These cushions provide good transverse rigidity, while supporting the tension cord, and also ensure optimal adhesion between the tension cords and the rubber cushion. The reverse side of the belt features a heavy-duty rubberised biased-cut industrial fabric that offers additional protection and flexibility. The CRE belts are currently available from SKF in lengths of up to 5000 mm.
