About this part

What it is and why it is made that way

An end housing has to locate the bearing and register with the motor frame — two fits that have to agree with each other. The casting is produced with the register as-cast and the bearing seat machined, and both are inspected from the same datum so the housing seats square in the frame.

  • Register and bearing seat machined from a common datum
  • Cast-in ribbing for stiffness without machining away material
  • Bearing bore finished to the specified fit
  • Aluminium and zinc alloy available

Materials

  • ADC12 / ADC3 aluminium
  • A380 aluminium
  • ZAMAK-5 zinc alloy
  • A356-T6 aluminium
  • Magnesium alloy

Production processes

  • Cold-chamber die casting
  • Hot-chamber die casting
  • High-pressure die casting
  • CNC trimming and milling
  • Shot blasting and leak testing

Typical applications

  • Electric motor end housings
  • Gearmotor end bells
  • Servo motor frames
