What is a Plane Bearing? Or is it a Plain Bearing?

March 26, 2015

What is a Plane Bearing? Or is it a Plain Bearing? First let’s settle this important question, is it a “plane” bearing or a “plain” bearing? And survey says? Both spellings are correct, although this bearing supplier prefers plane bearing. 

Now that we have that settled, the question then becomes, what is a plane bearing exactly? We have the answer to that question, too!

A plane bearing is really a bearing in its simplest form; it is any non-rolling element bearing that is applied where two surfaces rub together. Common forms are flange or sleeve bearings, slide plates or friction bearings. Some applications call for a reinforced plane bearing with unique liners, while others demand a particular material surface finish as demonstrated in this video

Plane bearings are comprised of materials ranging from composites, bronze, and acetals to carbon alloy. Ultimately to get the right fit for your plane bearing application, consider:

  • Bearing load
  • Relative velocity
  • Operating temperature variations
  • Environmental conditions
  • Machinability
  • Cost

For more details, check out our popular Rulon plane bearings which excel in high-temperature, non-lubricated applications, or Ask an Expert for a recommendation.
