Industrial Transmission Belts

Product description

The ROFLEX RE-X classical V-belt is of the raw-edge type with moulded cog. The belt is resistant to oil and temperature stresses as well as antistatic. 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. A special rubber compound with textile fibres oriented across the belt length resists deformation of the belt and provides great wear resistance. The belt keeps a constant friction level for the remainder of its life after running in.
The belts are tolerance stable, TS, allowing it to be used in matched sets without sorting.

Application

ROFLEX RE-X has higher power ratings, greater efficiency and longer life than other belt types in classical sections. It is able to operate with smaller pulley diameters, higher belt speeds and speed ratios. Drives can therefore be made in more compact, space-saving designs and at a lower overall cost.
ROFLEX RE-X are recommended for installation in new drives.
Moreover, it may be more economical to use ROFLEX RE-X belts when replacing the V-belts in existing drives.
