Pulley Description
SPC 355-6 TB 3535 (typ 6) is a V-belt pulley for Taper Lock bushes. It is made of grey cast iron. Its design is based on the ISO 4183 (DIN 2211) standard.
The pulleys are mounted to the shafts using Taper Lock cone bushes (TB 3535), thanks to which there is not only the fixing on the shaft with a keyway, but also the axial locking against displacement.
Typical Applications
The SPC V-belt pulleys for Taper bush 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.
Materials
Fine grain cast-iron grade 220–260.
Other materials to order.
