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.
The TRASCO ES consist of two hubs, which are either made of high-strength aluminium (up to the 38/45 size) or steel (from size 42) that are connected with an elastic element.

Built to ASME / ANSI B29.1 standards for dimensions, interoperability, and sprocket fit, the ASME / ANSI Standard Roller Chain series also meets Diamond Chain’s rigorous internal requirements. From industry to agriculture, our Standard Series chains are designed to fit a wide variety of standard applications, and to last longer than any other manufacturer’s chain.

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.

Here are the dimensions of "PBT" SPZ with taper bush 1210 :
- Belt type : SPZ
- Taperbush : 1210
- Shaft diameter range : 12 - 32 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT075SPZ2 (1210); so, the pitch diameter is 75 mm
- Outside diameter : you can add the pitch diameter with 4 to know the length of outside diameter.
For example, the product is PBT075SPZ2 (1210); so the outside diameter is 75 + 4 = 79 mm
- Groove : refer to the last number in every product name.
