ROFLEX RE-X Narrow V-Belts

Product description

The ROFLEX RE-X narrow V-belt is a raw-edge type with moulded cog. A special rubber compound wiht textile fibres oriented across the belt length resists deformation of the belt and provides great wear resistance. The moulded cog provides high flexibility and a good fit in the pulley grooves as well as a lower operating temperature which extends the belt's life. The belt keeps a constant friction level for the remainder of its life after running in. ROFLEX RE-X is resistant to oil and the stress of temperatures. This type of belt is both antistatic and tolerance stable TS, and it can be used in matched sets without sorting.

Application

We recommend using ROFLEX RE-X in new drive designs. The belt has a higher power rating, greater efficiency and longer life than other belt types, and it is able to operate with small pulley diameters, high belt speeds and speed ratios. Drives can therefore be made in more compact, space-saving designs and at a lower overall cost. Moreover, it may be more economical to use ROFLEX RE-X V-belts when replacing the V-belts in existing drives.
