Application

Mechanism for closing a bus, train or tram door.

Advantages

  • Wear-resistant steel alloy
  • Smooth surface, also on cast gearing
  • Savings in material costs and processing costs
  • Casting of the gearing and square axle hole without post-processing

Advantage of the CIREX casting process

No processing required for the gearing: the entire profile of the teeth can be cast. Therefore, only a broaching process  of the pre-cast square assembly hole is required. This achieves significant cost savings. Component is delivered ready to be built in, including (black) galvinising.
