Pulley Description
48 XH 200 (Type 9A) TB 3020 (Cast Iron) is a basic type of pulley for belts with trapeziodal XH profile. It is made of gray cast iron. Its design is based on the ISO 5294 standard.
The pulleys are mounted on shafts using the Taper Lock bushes (TB 3020), thanks to which there is not only a fixing on the shaft with a keyway, but also an axial locking against displacement.
Pulley Fields of Use
The XH Taper timing pulleys are designed for all types of XH belts with pitch 22.25 mm.
They are typically used in older machines with lower and medium performance, for example in packaging machines, in the ceramic, textile, food and tobacco industry and in many other machines. In new applications, they are often replaced by HTD, STD or CTD profiles.
