Industrial Transmission Belts

ROFLEX-X Classical V-Belts

Product description

ROFLEX-X is a raw-edge classical V-belt type with moulded cog which is temperature and oil resistant as well as antistatic. The belts are tolerance stable, TS, such that belts with the same section and length marking can be used immediately in matched sets.
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 classical V-belts; it has a wide range of applications, especially in industrial drives with high belt speeds and small pulley diameters.
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.

Standards

ROFLEX-X classical V-belts:
ISO 4184, BS 3790, DIN 2215, ANSI/RMA IP-20 etc.

Pulleys:
ISO 4183, BS 3790, DIN 2211/1, ANSI/RMA IP-20 etc.
