Pulley Description

56 L 100 (Type 6W, Cast Iron) is the basic timing pulley for inch belts with L trapeziodal profile. It is made of grey cast iron with a pilot bore. Designed according to ISO 5294.

The pulleys are supplied as a semi-finished product and the internal hole must be modified before mounting the pulleys on the shafts.

Pulley Fields of Use

The L standard timing pulleys are designed for all types of L belts with pitch 9.525 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 HTDHigh Torque Drive

Because of its tooth height and semi-circular tooth geometry, the HTD profile is especially good at avoiding jump-over of the teeth in operation. The HTD profile is extremely suitable for transmitting high torques.
, STDSuper Torque Drive

The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds.
or CTDConti Torque Drive

The CTD profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running.
