Standard Timing Bars

Timing bars serve as a semi-finished product for the production of timing pulleys. They are produced in different profiles, which correspond to the belt profiles. The basic types are made of aluminum alloy, alternatively steel, depending on the profile. Their standard lengths are usually 160 mm (or 140 mm).

Timing bars for all 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.

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.
or GTRThe GTR 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. It also incorporates an additional groove in the tooth head, which enables the air to escape gently from the tooth gap, further enhancing its smooth running. profile.

AT (for PU Belts)

Timing bars for polyurethan timing belts with trapezoidal ATThe AT profile is a further development of the T (Trapezprofil) profile. The teeth have a higher load capacity because of the increased tooth volume. The optimized flank angle results in improved tooth meshing. Here, too, a play-free belt/sprocket pairing that results in unsurpassed precision can be achieved. profile.


Bars Fields of Use

Timing bars are designed for production of timing pulleys of any shape. They are used when, for any reason, the corresponding timing pulley is not available or is not standardly produced.

As well as the timing pulleys, they are used in machine tools, packaging machines, printers, single-purpose machines, in the food, paper and glass industries and in many other industries.
