In the event of an emergency, we are at your disposal NONSTOP even outside our normal operating hours.
The toothed pulleys clamped on the shafts together with the belt which belted, a mechanical drive used to transfer energy between the shafts. Thanks to the transverse gearing, which prevents slippage, this drive is is synchronous and can ensure precise timing and positioning of the individual shafts relative to each other.
We offerclassic toothed pulleys in stock in complete dimensional ranges. Delivery time for non-stock items ranges from 3 to 14 days.
Self-guiding pulleys (except SilentSync type) we offer after request with a delivery time of 5 weeks.
Classic Self-guiding (selftrack)
with transverse gearing with special gearing
The pulleys are manufactured in a specific, predetermined design (shape and material Technical information about each specific pulley offered can be found in our catalogue or in our e-shop in the product details
For TB housing
Pulley with hub ready for TB Taper bush (Taper Bush). The TB bush must be ordered separately, according to specific shaft diameter.
Full charge
The pulley has a full hub in which it is necessary drilled to the required diameter before assembly. The pulley can be clamped with a tongue / groove system or with a clamping sleeve.
Hub for TB holster
The pulley has a tapered hole in the hub for a specific TB number case. Each case number is produced in multiple variations for different shaft diameters. When ordering a TB bushing, which is ordered separately, it is necessary to know its number (part of the TB pulley name) and the shaft diameter, on which the bushing is to be fitted. E.g. bushing designation TB2012-25 indicates the bushing number 2012 and the 25 mm shaft diameter on which the the bushing and pulley can be fitted. During assembly, the bushing is inserted into the hub and loosely, by hand only, into the the mounting screws are screwed into the pressed holes. This set is is seated on the shaft so that the tongue fits easily into the groove. Tightening the screws the sleeve is pressed into the hub and held firmly on the shaft. The TB bushing is can also be used on shafts without a groove without the use of a locking pen. However, this will reduce the amount of maximum torque transmitted.
Full hub
The pulley has a full hub. Before mounting, a hole must be drilled in the hub with the same diameter as the shaft to be fitted and a groove for the tongue. After this preparation, the pulley is slipped onto the shaft and secured with a feather. The preparation of the pulley with a full hub is more demanding than for clamping TB bushing. However, in non-typical or mini applications, it has the use of full hub pulleys is justified.
When using a clamping sleeve, a locking pen is not used. In the hub a cylindrical hole is simply drilled in the collet to match the outer diameter of the clamp of the clamping sleeve. The sleeve is inserted into the hole in the hub and the whole assembly is slipped onto the the shaft. After tightening the mounting screws of the casing, the pulley is fixed fixed on the shaft.
