• 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 1610 :
• - Belt type : SPZ
• - Taperbush : 1610
• - Shaft diameter range : 12 - 42 mm
• - Pitch diameter : refer to numbers writen after "PBT" in every product name. 
• For example, product name : PBT085SPZ2 (1610); so, the pitch diameter is 85 mm
• - Outside diameter : you can add the pitch diameter with 4 to know the length of outside diameter. 
• For example, the product is PBT085SPZ2 (1610); so the outside diameter is 85 + 4 = 89 mm
• - Groove : refer to the last number in every product name. 
• For example for PBT085SPZ2; so, the groove is 2
