Discussion Overview
The discussion revolves around selecting an appropriate bearing for a rectangular plate that needs to move smoothly up and down on rods without binding. The context includes considerations of bearing types, material compatibility, load capacity, and design implementation.
Discussion Character
- Technical explanation, Conceptual clarification, Debate/contested
Main Points Raised
- One participant inquires about suitable bearings for smooth vertical movement on rods.
- Another participant suggests using simpler alternatives to rolling bearings and questions their lifetime compared to other options.
- A third participant recommends using a Danly die set, which typically employs linear bearings or bushings.
- Another participant confirms the use of linear bearings and suggests searching for options on McMaster Carr or Grainger.
Areas of Agreement / Disagreement
Participants generally agree on the suggestion of using linear bearings, but there is no consensus on the specific type or model of bearing that would be best suited for the application.
Contextual Notes
Considerations include the material of the rods (aluminum or stainless steel), the diameter of the shafts (5/16" to 1/2"), and the load of approximately 8 kilos on the plate. There may be unresolved questions regarding the lifetime and performance of the suggested bearings.
Who May Find This Useful
Individuals interested in mechanical design, bearing selection, or those working on projects involving linear motion systems may find this discussion relevant.

Thanks for the suggestion. Simpler than a rolling bearing. Does it have comparable lifetime? The shafts could be aluminum or stainless steel, about 5/16" to 1/2" (8mm-12mm) diameter. There would be a load of approximately 8 kilos sitting on the plate. I could use opposing bearings on either side of the plate, screwed to the plate, a pair on each corner. The plate is moving, the rods are stationary.

Use something similar to a Danly die set www.danly.com

Your drawing resembles a press die set, as mentioned by tygerdawg, which use linear bearings or bushings.
A search for "linear bearings" should keep you busy for a while.

I second the linear bearings suggestion. Search for this on McMaster Carr or Grainger. I'm sure you'll find what you need.
