Detailed Description:

  • LuBo #500 Series Self-lubricating Bearings can be utilized where heavy loads must be supported at low to medium speeds.
  • Bearings have high mechanical strength with excellent wear resistance and self-lubrication properties exhibiting stable performance and durability under severe operating conditions.
  • No form of supplementary lubrication is required. A film of solid lubricant is transferred to the shaft as it starts to run.
  • In operation, both surfaces burnish quickly and result in a highly polished bearing surface capable of withstanding extreme pressure

LuBo #500 Series Materials

  • Normally, copper alloy is used as the base material for LuBo #500 series bearings by centrifugal or sand casting. Other materials such as cast iron, stainless steel and even tool steels could be used according to the applications involving extreme temperatures, environments corrosive to bronze, and loads exceeding the compression strength of bronze.

Guided Ejector Pin and Bushing

Guided Ejector Bushings

Function: The function of the Guided Ejector System (Pin and Bushing) is to take the pressure off the Return Pins, Ejector Pins and the Sprue Puller Pins. If the mold is set to run with the Ejector system actuation in the horizontal position (typical), the ejector sub assembly is cantilevered, and thus will put stress on the return, sprue and ejector pins. The Guided Ejector System will reduce if not eliminate these stresses.

The Guide bushing is located between the Ejector and Ejector Retainer Plates, and the Guide Pin is placed either in either:

1. The bottom of the Ejector Housing, or

2. In the Support Plate. In either case the Pin resides in the open space of the ejector housing

Guided Ejector Bushings come in a variety of industry standard sizes. If a standard size won’t work for your application,please kindly let us know, we can make the bushing as customized.
