Pulleys or synchronising pulleys are used with drive solutions with timing belts. Transmission accuracy, service life and also smooth and quiet running are crucially influenced by the precision of the interaction between the timing belt and the pulley. Synchronous pulleys are classified according to the defined standards of the timing belts, number of teeth, pitch, pulley width and abbreviation for the model.
The selection of the correct tooth gap shape is crucial for the accuracy of the overall timing belt system. The smaller the “gap” between the timing belt and synchronising pulley, the greater the benefits for linear drives and systems with exact positioning and repeat accuracy.
Please refer to the respective data sheet for more detailed properties of the individual components.
AT
The AT profile is a further development of the standard T profile and, in particular, provides higher tooth strength resulting from the larger tooth volume and stronger tension members.
Benefits:
- Favourable tooth mesh
- Up to 50% improved performance over the T profile
- Precise transmission of movement
AT 3
Pulleys or synchronising belts with an AT 3 pitch are intended for use with timing belts with an AT 3 profile.
They are available in the widths 10, 15, 22, 32 and 40 and are used for belt widths of 6, 10, 16, 25 and 32. AT 3 synchronising pulleys can be supplied with 15 to 114 teeth.
Other dimensions are available as non-standard products.

ATP
Further increased performance, noise reduction and extended service life led to the development of the ATP profile. The new shape of the teeth creates 60% increased performance and a reduction in running noise by up to 10 dB(A).
Benefits:
- Narrower construction width
- Higher performance
- Uniform tension distribution
ATP 10
Pulleys or synchronising belts with an ATP 10 pitch are used together with timing belts with an ATP 10 profile.
They can be used in widths 23, 32, 40, 60, 85 and 110 and are used for belt widths of 16, 25, 32, 50, 75 and 100. ATP 10 synchronising pulleys can be supplied with 15 to 114 teeth.

T
The T profile is the classic of timing belt profiles and the standard profile conforms to DIN 7721. Its trapezoidal profile means that its preferred fields of application include standard drives with higher flexing.
T 2
Pulleys or synchronising belts with a T 2 pitch are used together with timing belts with a T 2 profile.
They come in widths 8, 10 and 14 and can be used for belt widths 4, 6 and 10. T 2 synchronising pulleys can be supplied with 15 to 114 teeth.
Other dimensions are available as non-standard products.

Self-tracking
Self-tracking profiles are suitable for use with drives of all kinds and can be used within a speed range of up to 10,000 rpm. They are suitable for continuous operation and also start-brake operation.
BAT 10
Pulleys or synchronising belts with a BAT 10 pitch are used together with self-tracking timing belts with a BAT 10 profile.
They are available in widths 30, 35, 55, 80 and 105 and are used for belt widths 25, 32, 50, 75 and 100. BAT 10 synchronising pulleys can be supplied with 20 to 114 teeth.

Imperial
Imperial profiles are classified according to DIN/ISO 5296 and are suitable for use in imperial systems.
M / MXL / Mini-Pitch
Pulleys or synchronising belts with an imperial M pitch are used together with the matching timing belts with an M profile.
They come in widths 8, 10 and 14 and can be used for belt widths 4, 6 and 10. The imperial M profile synchronising pulleys can be supplied with 15 to 114 teeth.

HTD
The HTD (High Torque Drive) profile features a special tooth height and curvilinear tooth geometry. This timing belt profile therefore offers an extremely good guarantee against the teeth jumping and is therefore suitable for the transmission of high torques
3M
Pulleys or synchronising belts with an HTD 3M profile are used together with the matching timing belts. The pulleys are available for belts widths 6.00 to 15.00 mm. 3M profile synchronising pulleys can be supplied with 10 to 72 teeth.

STD
The STD (Super Torque Drive) profile features an arc-shaped geometry, which ensures optimum tooth meshing.
Special manufacture on request.
CTD
The CTD profile (Conti Torque Drive) was developed as the symbiosis of the HTD and STD profile. The arch-shaped entry geometry combined with raised teeth is how the CTD profile unites the benefits of both profiles.
