Plain Bearing
Plain bearings are very similar in design to rolling-element bearings, except they slide without the use of ball bearings.
- Plain bearings can run on hardened steel or stainless steel shafting (raceways), or can be run on hard-anodized aluminum or soft steel or aluminum. The specific type of polymer/fluoro-polymer will determine what hardness is allowed.
- Plain bearings are less rigid than rolling-element bearings.
- Plain bearings handle contamination well and often do not need seals/scrapers.
- Plain bearings generally handle a wider temperature range than rolling-element bearings
- Plain bearings (plastic versions) do not require oil or lubrication (often it can be used to increase performance characteristics)

Famous quotes containing the words plain and/or bearing:
“Nothing astonishes men so much as common sense and plain dealing.”
—Ralph Waldo Emerson (1803–1882)
“At sundown, leaving the river road awhile for shortness, we went by way of Enfield, where we stopped for the night. This, like most of the localities bearing names on this road, was a place to name which, in the midst of the unnamed and unincorporated wilderness, was to make a distinction without a difference, it seemed to me.”
—Henry David Thoreau (1817–1862)
