Our pulleys can be used for application with a speed up to 35m/s. The pulley dimensions are very accurate as they are manufactured only by means of CNC or automatic lathes.
For higher speed is strongly recomended to use steel as material of construction. Our PBT pulleys are satically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
Here are the dimensions of "PBT" SPZ with taper bush 1108 :
- Belt type : SPZ
- Taperbush : 1108
- Shaft diameter range : 11 - 28 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT063SPZ2 (1108); so, the pitch diameter is 63 mm
- Outside diameter : you can add the pitch diameter with 4 to know the length of outside diameter.
For example, the product is PBT063SPZ2 (1108); so the outside diameter is 63 + 4 = 67 mm
- Groove : refer to the last number in every product name.
TOP DRIVE® HTD belt is an evolution of standard positive drive belts. The tooth shape is the HTD profile according to ISO 13050.
This profile has been used for many years in a wide range of applications and it is well known for its outstanding performances. Power transmission is much higher compared to the classic inch trapezodial profile.
The circular-arc tooth provides superior tooth jump resistance and provides a smooth tooth engagement. The noise level is remarkably reduced if compared to the classic trapezodial belts.
standard connecting links are used when roller chains are operated under normal conditions. for severe applications, press fit connecting links are suggested.
Keyways are British Standard Metric B S 4235. Part 1: 1972 DIN 6885 and conform to ISO recomendations with the exception of those marked, which are shallower. Where a key is to be used it should be parallel and side fitting, with top clearance. Depth of keyway is measured at the CENTRE
SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The hubs are made of steel and the teeth, which are both profiled and section crowned, are obtained from milling. The sleeve is manufactured from stabilized 6.6 superpolymade resin.
HRC couplings offer a range of hub and element selection to meet the demand for a low cost, general purpose spacer type flexible coupling. They allow for incidental misalignment, absorb shock loads and dampen out small amplitude vibrations. They are offered in both pilot bore, finished bore, Finished bore, and Taper bushed with both face and hub mount.
