Flanged Bushings

[TomP]

There is a little more to a bushing than just making the hole smaller...the major consideration is if the bushing can handle the load without deformation.
Three things come into play: Load (P) in psi, velocity(V) and load at velocity (PV). ergo:
P=bearing load/shaft dia x bearing length
V=shaft velocity x 0.262 constant x shaft dia
PV= P x V

Use the PV as a final check to ensure that the bearing can sustain the combined load and velocity requirements.

In all but the most extreme cases you will want to use Alloy 954 Bronze or SAE 841 Bronze-also called Oilite.

Hi Tom,
I believe Douglas is inquiring about a static bushing. Something to spread the load or compensate for a corroded area or spread a vibration load area, etc..
