Materials and Features

Materials:

Our PT-PBT and PCT pulleys are made of cast iron, quality DIN 1691 GG20 - GG25.

 

Features:

The dimensions are very precise as the pulleys are turned exclusively by means of CNC or automatic lathes. These pulleys can be used for speed up to 35 m/s.

Protective Treatment:

Out PT-PBT and PCT pulleys are black phosphated.

 

Balancing:

Our PBT pulleys are statically balanced UNI 4218 - VDI 2060, G6, 3 degree (at 1.500 rpm up to PD = 400mm and at 35 m/s over PD = 400mm). The PT and PCT pulleys are not balanced as they do not have a finished bore.
