SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The hubs are made of steel and the teeth, which are both profiled and section crowned, are obtained from milling. The sleeve is manufactured from stabilized 6.6 superpolymade resin.
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.

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" SPB with taper bush 1610 :
- Belt type : SPB
- Taperbush : 1610
- Shaft diameter range : 12 - 42 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT100SPB1 (1610); so, the pitch diameter is 100 mm
- Outside diameter : you can add the pitch diameter with 7 to know the length of outside diameter.
For example, the product is PBT100SPB1 (1610); so the outside diameter is 100 + 7 = 107 mm
- Groove : refer to the last number in every product name.
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 1210 (30.25)
- Bore : we provide taper bushing with minimal bore 12 mm and 5/8 inches; for the max bore you can look at the number writen after "BC" in every product name.
for example, BC3025F12 (1210X12MM), so the max bore is 30 mm.
- Width : the numbers writen in every product name before "F" is width size.
for example, BC3025F12 (1210X12MM), so the width is 25 mm.
- Bore size : look at the last number in every product name.
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.
This type of coupling premits quick, sure fixing, without any shaft-hub backlash.

Joints with plain bearings are available in 2 versions :
- Types E to DIN 808;
- Type EB to DIN 808/7551
Precision joint series "E" (DIN 808) wear resistant sliding bushes from cemented and hardened steel. Strong, precise, and versatile; wide application field.
Max. angel : 45° type "E", 90° type "ED". Max. speed 1.000 rpm.
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.
TRASCO flexible couplings is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmision by absorbing peak loads and torsional vibrations.
