SPC Standard V-Belt Pulleys
SPC Standard solid hub V-belt pulleysare the basic type of V-belt pulleys. They are produced in standard series and dimensions. They are made of gray cast iron.
The V-belt pulley design is based on DIN 2211 and ISO 4183 standards.
The pulleys are supplied as semi-finished products and the bore must be modified before mounting the pulleys on the shafts.
Pulleys Fields of Use
The solid hub SPC 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 engineering.
They are typically used in compressors, blowers, machine tools, in the paper and chemical industry and in many other machines.
Pulleys Material
Fine grain cast-iron grade 220-260.
Other materials to order.
