• 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" SPB with taper bush 1610 :
• - Belt type : SPB
• - Taperbush : 1610
• - Shaft diameter range : 12 - 42 mm
• - Pitch diameter : refer to numbers writen after "PBT" in every product name. 
• For example, product name : PBT100SPB1 (1610); so, the pitch diameter is 100 mm
• - Outside diameter : you can add the pitch diameter with 7 to know the length of outside diameter. 
• For example, the product is PBT100SPB1 (1610); so the outside diameter is 100 + 7 = 107 mm
• - Groove : refer to the last number in every product name. 
• For example for PBT100SPB1; so, the groove is 1

•  
• Here are the dimensions of Taper Bushing with type 1108 (28.20)
• - Bore : we provide taper bushing with minimal bore 9 mm and 3/8 inches; for the max bore you can look at the number writen after "BC" in every product name. 
• for example, BC2820F10 (1108X10MM), so the max bore is 28 mm.
• - Width : the numbers writen in every product name before "F" is width size.
• for example, BC2820F10 (1108X10MM), so the width is 20 mm.
• - Bore size : look at the last number in every product name. 
• for example, BC2820F10, so the bore size is 10.
