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.
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.
Locking elements consist of one internal and one external tapered rings. They are designed to work in combination with a clamp flange which can be bolted on a hub or shaft depending on application need.
Here are the dimensions of product :
Inner Diameter : refer to numbers writen after "F" in every product name. For example, CAL2F10/13; so, the inner diameter is 10 mm.
Outside Diameter : refer to the last number in every product name. For example, CAL2F10/13; so, the outside diameter is 13 mm.
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.
Coupling are available from stock, both the standard and the "long" hub execution, which entirely covers the motor shaft.
Here are the dimensions of couplings with"long" hub execution :
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 1610 (40.25)
- Bore : we provide taper bushing with minimal bore 12 mm and 3/8 inches; for the max bore you can look at the number writen after "BC" in every product name.
for example, BC4025F12 (1610X12MM), so the max bore is 40 mm.
- Width : the numbers writen in every product name before "F" is width size.
for example, BC4025F12 (1610X12MM), so the width is 25 mm.
- Bore size : look at the last number in every product name.
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.

Here are the dimensions of Taper Bushing with type 1615 (40.40)
- Bore : we provide taper bushing with minimal bore 12 mm and 1/2 inches; for the max bore you can look at the number writen after "BC" in every product name.
for example, BC4040F12 (1615X12MM), so the max bore is 40 mm.
- Width : the numbers writen in every product name before "F" is width size.
for example, BC4040F12 (1615X12MM), so the width is 40 mm.
- Bore size : look at the last number in every product name.
Of this series both single and double joints are available.Types E are with sliding bushes while type H has needle roller bearings.
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.
Locking assembly with single taper design. Consists of two tapered rings and a spacer. It has minimum overall dimensions in virtue of the reduced thickness of the cones.
SIT-LOCK® 3 is suitable for the applications where small hubs are requested. It is recommended for mid-high torques and is self centering.
For the dimension of the product, please download the catalog in the document section
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.
