Extruded pulley components

Extrusion technology for aluminum pulleys

Cold extrusion technology offers a cost-effective alternative in the production of aluminum pulleys. In addition to reducing the amount of steps in production, it also offers the following advantages:

  • No milling of the teeth required
  • High surface quality of the tooth geometry (Ra 0.5 to 4.0)
  • Final contour accuracy production of functional surfaces
  • Hardening T6 after pressing (if required)
  • Integrated flanged wheel (one-sided) = no mounting required
  • Extruded frictional elements (keyway and driver)
  • Maximum component size 80 mm

In combination with CNC post-processing the complex geometry of parts can be produced at low production costs.
