Inch Sizes Timing Pulleys
Inch sizes timing pulleys are the basic type of inch sizes pulleys. They are made of steel, gray cast iron or aluminum alloy. Designed according to ISO 5294.
Standard
Pilot Bore Timing Pulleys XL, L, H, XH for timing belts with trapezoidal profiles and inch pitch.
Taper Lock
Taper Bore Timing pulleys L, H, XH for timing belts with trapezoidal profiles and inch pitch.
Pulleys Fields of Use
The inch sizes timing pulleys 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. profiles.
