Industrial Transmission Belts
ROFLEX Narrow V-Belts
Product description
ROFLEX-X is a raw-edge narrow V-belt type with moulded cog which is temperature and oil resistant as well as antistatic. The belt is tolerance stable TS, such that belts with the same section and length marking can be used in matched sets without matching. The moulded cog provides high flexibility and a good fit in the pulley grooves as well as a lower operating temperature, which increases belt life.
Application
ROFLEX-X is ROULUNDS new programme within narrow V-belts; it has a wide range of applications, especially in industrial drives with high belt speeds.
This new programme allows immediate improvement of existing drives which use wrapped belts, providing overall benefits with regard to economy as well as power transmission and reliability of operation.
