Berges KRM type double pulley & belt drive system is for lighter hp applications where a standard V-belt can be used.  The Adjusting pulley is the KR and the Spring Tensioning pulley is the KM; together being KRM.  These are designed to work with the standard narrow metric V-belts in the 10, 13, and 17mm widths.  The same time proven design as the RF..b is employed, but for narrower belts and lower power. The power range is in the very popular 1/2hp to 1.5hp range, with a 6/1 variable ratio, and speeds around 670 to 4000 RPM.  Ideal for a wide variety of applications where reliable variable speed is desired, and cost effective ratio control for applications from wood working tools to pumps; great variety of drive applications is driven by  the KRM. TVT America's Engineering & Sales team is here to assist you with all of your Berges Variable Pitch Pulley & Belt questions, sales, and engineering inquiries.
