Transcyko CORC Counter Rotating Conical Twin Screw Rubber Extruder Gearboxes
CORC counter rotating conical twin screw rubber extruder gearboxes provide optimum mixing efficiency for manufacturing PVC and other specific rubber and plastic material processes that benefit from high torque mixing capabilities and the ability to sustain heavy loads during the production cycle.
Conical twin screw extruder gearboxes
Featuring a larger diameter at the feed and smaller diameter at the output die, the design geometry of conical twin screw extruder gearboxes results in a greater distance between the output shafts at the gearbox end compared to the output end of the extruder.
- Uprated thrust & radial bearings can be fitted to conical extruder gearboxes
- Larger output shaft diameters enable increased torque without increasing footprint
- More space for heavy duty gears and components
Transcyko conical twin screw extruders use the larger center difference created by the angled axis of the output shafts to optimize the placement and size of the gears, drive shaft and bearings. The ability to install larger thrust and radial bearings, and shafts of greater diameter at the gearbox, makes it possible to both improve the efficiency of the extruder gearbox and to increase the maximum torque.
Increased load bearing capacity and higher torque capabilities of conical twin screw extruders
Increased load bearing capacity and higher torque capabilities are the most immediate benefits of Transcyko conical twin screw extruders when compared to parallel twin screw extruders, but the conical configuration is not suited to every type of extruder, and needs to be matched to the specific compound or process requirements.
Conical twin screw extruder gearboxes for mixing & plasticizing of PVC
One example of the specific material applications of conical twin screw extruder gearboxes is their use for processing PVC, but extruders using conical twin screw gearboxes can be optimized for a range of specific material processing needs. The limitation of conical twin screw rubber extruder gearboxes is the varying diameter of the screw, which enables very efficient mixing and plasticizing but makes smooth and uniform processing more dependent on specific viscosity characteristics of the material being processed.
Conical twin screw extruders share the material advance, mixing and plasticizing functionality of parallel screw extruders but are less flexible in terms of material type. They have the added benefit that their unique geometry makes them capable of higher torque and increased durability compared to an equivalent physical size of parallel screw extruder gearbox.

Conical or parallel counter rotating twin screw extruders
Your extruder application determines your choice of conical or parallel counter rotating twin screw extruder, and conical and parallel extruder gearboxes have different design requirements that change the screw alignment, barrel geometry and gearbox assembly.
When deciding between counter rotating twin screw extruder gearbox options the easiest way to finalize your requirements is to contact us and discuss your needs with our in-house engineers. Transcyko is a vertically integrated gearbox design and manufacturing specialist, and our concentration of expertise makes it comparatively easy for us to identify the best, most efficient and cost effective solution for your extruder design.
Manufacturing quality of extruder gearboxes
Transcyko twin screw extruder gearboxes are manufactured to very high quality standards, which increase longevity and reliability while also improving efficiency and ease of maintenance. Transcyko CORC counter rotating conical twin screw rubber extruder gearboxes are able to use larger thrust bearings on the output shafts due to the geometry of conical twin screw extruder designs.
The larger thrust bearings on Transcyko conical twin screw extruder gearboxes reduce bearing wear by resisting the high axial loads required for efficient processing. This maintains efficient, high quality mixing for a longer time between routine maintenance duty cycles.
DIN4 gear grinding for conical twin screw extruder gearboxes
Transcyko gear grinding for our conical twin screw extruder gearboxes uses state of the art gear grinding technology to the DIN4 German DIN 3962 standard (JIS 0). This high precision standard reduces wear and eliminates the risk of premature failure that is a common issue with twin screw extruder gearboxes that operate under very high torque loads.
Transcyko makes gearboxes for all types of extruders
Transcyko single and twin screw rubber extruder gearboxes are manufactured to the highest quality standards to complement your OEM rubber extruder design. We design and manufacture all our gearboxes with awareness of the need to minimize servicing and maintenance costs and to make servicing and maintenance as easy as possible.
High precision DIN4 gear grinding, high quality bearings and efficient, customizable, cooling systems contribute to the legendary reliability of Transcyko extruder gearboxes.
