Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Porous bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If the bearing’s load and speed are below the values listed, the bearing should work for your application.
