Manufactured from ethylene propylene diene monomer (EPDM) synthetic rubber, Cogged Raw Edge (CRE) belts offer users increased efficiency and improved longevity, helping to reduce input costs and improve productivity.

SKF says its ISO 4148-compliant CRE belts are ideally suited for any industrial applications that run on ISO wedge and classical V-belt pulleys.

“Cornerstone to our tough and reliable CRE belts is the EPDM manufacturing compound,” notes SKF product manager: power transmission Micaela Willers. She explains: “This durable composite provides excellent flexibility as well as 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 °C to 120 °C. These belts have higher power ratings, they wrap better and ultimately are more efficient than ever.”  

Further extending the life cycle of the CRE belts are tension cords manufactured from pre-tensioned, stabilised rubber-impregnated polyester yarn that minimise belt elongation during operation.

The design of the belt incorporates an upper support rubber cushion manufactured from fibre-loaded EPDM compound. These cushions provide 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 available from SKF in lengths of up to 5 000 mm.
