• 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 1108 :
• - Belt type : SPA
• - Taperbush : 1108
• - Shaft diameter range : 11 - 28 mm
• - Pitch diameter : refer to numbers writen after "PBT" in every product name. 
• For example, product name : PBT075SPA2 (1108); so, the pitch diameter is 75 mm
• - Outside diameter : you can add the pitch diameter with 5.6 to know the length of outside diameter. 
• For example, the product is PBT075SPA2 (1108); so the outside diameter is 75 + 5.6 = 80.6 mm
• - Groove : refer to the last number in every product name. 
• For example for PBT075SPA2; so, the groove is 2 
•  
• See recomendation taperbush below.

• SIT TAPER LOCK BUSHING is designed to give the following:
• 1. Perfect assembly
• 2. rapid dismantling of the pulley and other transmission equipment
• 3. No special tools requirement except hexagonal key
•  
• The large range of finished bores available ensures that an immediate assembly can be made thus avoiding costly factory down-time.
•  
•  
• Here are the dimensions of Taper Bushing with type 3039 (75.75)
•  
• - Bore : we provide taper bushing with minimal bore 25 mm and 1-1/4 inches; for the max bore you can look at the number writen after "BC" in every product name. 
• for example, BC7575F25 (3030X25MM), so the max bore is 75 mm.
• - Width : the numbers writen in every product name before "F" is width size.
