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.
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.
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 statically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The sleeve is manufactured from stabilized 6.6 superpolyamide resin.
The torsional rigidity of the sleeve prevents angular speed variation. The combination of steel hubs with polyamide sleeve makes the coupling maintenance and lubrication free.
The particular toothed profile prevents contact of tooth edged with the sleeve, ensuring long life of the coupling.
The special OPTIGEAR profile allows very high torque transmission and the compensation of axal, angular and radial misalignment (only in the version with 2 hubs). The maximum recommended working temperature is -10 °C a + 80 °C.
SITEX® ST type "C" are standard type with 2 hubs and one sleeve. Offers compact, powerful design, and easy assembly.
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
