the bearing. Scratch marks may also be visible on the bearing surface. DAMAGING ACTION Dust, dirt, abrasives and/or metallic particles, present in the oil supply, embed in the soft babbitt bearing lining, displacing metal and creating a high-spot. The high-spot may be large enough to make contact with the journal causing a rubbing action

A plain bearing, or more commonly sliding bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction bearing), is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore, the journal (i.e., the part of the shaft in contact with the bearing) slides over the bearing surface.

Therefore, the bearing inner diameter is lined with a sacial material to absorb damage and to protect the journal surface (for radial bearings) or thrust collar (for thrust bearings) from damage. To serve as a sacial material, this lining should be softer than the journal surface and accept contact from hard contaminants in the lubricant.

A linear bearing includes a carriage and rolling element. The linear bearing is mounted on either a square or round rail depending on the requirements of the application. The rolling element of the bearing, whether it be ball or roller slides, helps move a load with ease. These are the basics which are adjusted and tweaked to fulfill a wide array of manufacturing and industry needs.

Normally, bearings allow the crank glide on a hydrodynamic film of oil between the bearing surface and journal. As long as there is a steady supply of clean, fresh oil flowing into the gap between the bearing and journal, everything is fine. The film only has to be a few microns thick to maintain protection.

2 · Mounted bearings are used primarily in machinery with exposed rotating shafting. They are used as take-up devices on the ends of conveyors and as flanged units along intermediate points. The bearings can be rolling element or journal bearing configurations. Mounted bearings are designed for bolt-on mounting and ease of replacement.

How to Determine Bearing Types

Figure 2. Layers of Journal Bearing Structure. Journal bearings operate in the boundary regime (metal-to-metal contact) only during the startup and shutdown of the equipment when the rotational speed of the shaft (journal) is insufficient to create an oil film. It is during startup and shutdown when almost all of the damage to the bearing occurs. 2

Linear Bearings and Rail Guides – Trimantec

A bearing is a machine element which supports another moving machine element (known as journal). It permits a relative motion between the contact surfaces of the members, while carrying the load.
