TRASCO® ES is our zero backlash coupling designed to compensate for misalignment and vibration dampening for indexing applications. The compact design of TRASCO® ES makes it the right choice for all precise motion applications.
SIT coupling hubs are available from stock with either solid hub or with finished bores of standard shaft diameters.
Diamond Chain British Standard Series Chains are manufactured to International Standards Organization metric dimensions (IS 606, BS228, DIN 8187) for dimensions, interoperability, and sprocket fit

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 3020 (75.50)
- Bore : we provide taper bushing with minimal bore 22 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, BC7550F22 (3020X22MM), so the max bore is 75 mm.
- Width : the numbers writen in every product name before "F" is width size.
for example, BC7550F22 (3020X22MM), so the width is 50 mm.
- Bore size : look at the last number in every product name.
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 1108 :
- Belt type : SPZ
- Taperbush : 1108
- Shaft diameter range : 11 - 28 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT063SPZ2 (1108); so, the pitch diameter is 63 mm
- Outside diameter : you can add the pitch diameter with 4 to know the length of outside diameter.
For example, the product is PBT063SPZ2 (1108); so the outside diameter is 63 + 4 = 67 mm
- Groove : refer to the last number in every product name.
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
