HRC couplings offer a range of hub and element selection to meet the demand for a low cost, general purpose spacer type flexible coupling. They allow for incidental misalignment, absorb shock loads and dampen out small amplitude vibrations. They are offered in both pilot bore, finished bore, Finished bore, and Taper bushed with both face and hub mount.
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 1210 :
- Belt type : SPA
- Taperbush : 1210
- Shaft diameter range : 12 - 32
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT080SPA2 (1210); so, the pitch diameter is 80 mm
- Outside diameter : you can add the pitch diameter with 5.6 to know the length of outside diameter.
For example, the product is PBT080SPA2 (1210); so the outside diameter is 80 + 5.6 = 85.6 mm
- Groove : refer to the last number in every product name.
HTD pulleys have a different design from the traditional toothed pulleys. The axial grooves are designed to allow the beltteeth to catch the pulley teeth with negligible triction. HTD Pulleys are available with full hub and for assembly with SER-SIT taper bushing.
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.

Admissible Temperature [°C] : the rang is between -30 and +90°C
TRASCO® couplings are dimensionally manufactured to hub types "A" and "B", the difference being the maximum shaft diameter which hubs can accpet (corresponding respectively to the first and second code number). The long hub execution "L" (allows full coverage of the motor shaft) is available in both "A" and "B" execution.
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
POWERLOCK locking assembly unit consists of four pieces with two inside double-one rings joined through a set of tightening screws. It is recomended for medium torques. Although it is not self centering, it can be easily assembled and diassembled.
