First let’s settle this important question, is it a “plane” bearing or a “plain” bearing? And survey says? Both spellings are correct, althoughthisbearing 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 orsleeve bearings, slide plates or friction bearings. Some applications call for areinforced plane bearing with unique liners, while others demand a particularmaterial 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
