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" SPA with taper bush 3535 :
- Belt type : SPA
- Taperbush : 3535
- Shaft diameter range : 45 - 90 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT1000SPA3 (3535); so, the pitch diameter is 1000 mm
- Outside diameter : you can add the pitch diameter with 5.6 to know the length of outside diameter.
For example, the product is PBT1000SPA3 (3535); so the outside diameter is 1000 + 5.6 = 1005.6 mm
- Groove : refer to the last number in every product name.
