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.
