Ejector Pin Bushings
 |  |
Eject parts smoothly from your mold. These bushings reduce friction between your ejector pins and plates, so they slide easily and wear out slowly. An external channel directs lubricant into these bushings, so you don’t need to line up your nozzle with the lubrication hole. Once the lubricant is inside, a figure-eight-shaped groove distributes it evenly along the surface.

Self-Lubricating Ejector Pin Bushings
 |
Eject parts smoothly from your mold without liquid lubricant—these bushings reduce friction between ejector pins and plates. These bushings have graphite plugs to help the pins slide without wearing your assembly.
