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
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 statically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.

Here are the dimensions of "PBT" SPB with taper bush 1210 :
- Belt type : SPB
- Taperbush : 1210
- Shaft diameter range : 15 - 50 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT090SPB1 (1210); so, the pitch diameter is 90 mm
- Outside diameter : you can add the pitch diameter with 7 to know the length of outside diameter.
For example, the product is PBT090SPB1 (1210); so the outside diameter is 90 + 7 = 97 mm
- Groove : refer to the last number in every product name.

TRASCO flexible couplings is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmision by absorbing peak loads and torsional vibrations.

SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The sleeve is manufactured from stabilized 6.6 superpolyamide resin.
The torsional rigidity of the sleeve prevents angular speed variation. The combination of steel hubs with polyamide sleeve makes the coupling maintenance and lubrication free.
The particular toothed profile prevents contact of tooth edged with the sleeve, ensuring long life of the coupling.
