Product specification

Pulleys made of black plastic with 2 flanges

For timing belt profile T2.5 width 6 mm

With high hardness and low friction coefficient they can be used in various set-ups, even under water.

Inside these die-cast parts made of acetal resin are some cavities caused by production. These parts should therefore not be drilled too deep.

Technical specification

Material: acetal resin, in die-cast version

Bore: machined

Color: black

General Information

Use for power transmission, bridging of large centre distances and alteration of transmission ratios.

For various applications in machinery and plant engineering, in laboratory technology, in industrial and food processing plants, as well as in model making.

Quiet operation and synchronous transmission of power

Maintenance-free. Lubrication is not required.

High efficiency up to 98 %

Belt pre-tension is required

T timing belts made of polyurethane with pitch 2.5 or 5 mm. Light-coloured belts with little abrasion. For standard applications in machine building and food technology, to be used on T pulleys.

AT timing belts made of polyurethane with pitch 5 mm. Reinforced type for high loads with low space requirements. To be used on AT pulleys.

HTD timing belts made of neoprene with pitch 3, 5 or 8 mm. For high power transmission even at high speeds.

Black belts with dark abrasion (not for laboratory operations / food processing). To be used on HTD pulleys.

Notes on mounting and usage:

Pulleys must be aligned (precisely positioned)

The belt tension has to be adjusted (The overall sum of tensioning and peripheral force must not exceed the permitted tensile force of the belt.)

At least one pulley must be equipped with flanges.

And at least 6 teeth should be engaged at any time.

Timing belt drives run without lubrication.

General Information T / AT

Classical, trapezoid profile in accordance with DIN 7721 with metric dimensions

Type T: Standard type for normal set-ups in sizes T 2.5 and T5 in several widths. T timing belts only run on T pulleys.

Type AT: Reinforced type for the transmission of higher torques in size AT 5 in several widths. AT timing belts only run on AT pulleys. Due to their lower flexibility AT timing belts require a larger pulley diameter than T timing belts.

Pulleys available in aluminium (some also in plastic)

T and AT drives are not backlash-free

Good resistance against oils, fats and many chemicals

The timing belts are made of light-coloured plastic with little abrasion

Material: PUR - Polyurethane with tensile members of steel (little lengthening)

Temperature range: -30 to +80 °C

Pitch: T2.5: 2.5 mm; T5: 5.0 mm; AT5: 5.0 mm

Overall height: T2.5: 1.3 mm; T5: 2.2 mm; AT5: 2.7 mm

Tooth height: T2.5: 0.7 mm; T5: 1.2 mm; AT5: 1.2 mm

Tensile force: T2.5: 120 N; T5: 330 N; AT5: 700 N (permissible tensile force at 10 mm belt width)
