standard connecting links are used when roller chains are operated under normal conditions. for severe applications, press fit connecting links are suggested.
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 statically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
Keyways are British Standard Metric B S 4235. Part 1: 1972 DIN 6885 and conform to ISO recomendations with the exception of those marked, which are shallower. Where a key is to be used it should be parallel and side fitting, with top clearance. Depth of keyway is measured at the CENTRE

Here are the dimensions of "PBT" SPC with taper bush 5050 :
- Belt type : SPC
- Taperbush : 5050
- Shaft diameter range : 70 - 125 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT1000SPC3 (5050); so, the pitch diameter is 1000 mm
- Outside diameter : you can add the pitch diameter with 9.6 to know the length of outside diameter.
For example, the product is PBT1000SPC3 (5050); so the outside diameter is 1000 + 9.6 = 1009.6 mm
- Groove : refer to the last number in every product name.
