V-Belt Pulleys
V-belt pulleys are designed for all types of V-belts, including banded V-belts. Their design is based on the ISO 4183 (DIN 2211) standard.
The shape of the V-groove is determined according to the DIN 2215 and DIN 2216 standards for narrow, classical and raw-edge V-belts.

Pulleys Fields of Use
V-belt pulleys meet the highest requirements of modern drive technology and are used in all areas of mechanical engineering, from fine mechanics to heavy mechanical engineering.
They are typically used in compressors, blowers, machine tools, in the paper and chemical industriy and in many other machines.
