Sealing Options for Self-Lubricating Bearings
contaminates. This is a result of the inability of the bearing surface to ingest the particulate. Self-lubricated bearing manufactures typically design bearing liners that are soft enough to ingest contaminants. Each manufacturer of this type of bearing uses a different construction to try to best solve

How Do Self-Lubricating Composite Bearings Compare To Other Bearing Materials?
Q: "How Do Self-Lubricating Composite Bearings Compare To Other Bearing Materials?". A: The Polygon PolyLubeTM bearing can be used as a replacement for traditional powdered metal bearings where concerns over grease, contaminants, galling, corrosion or weight are problems. In addition, traditional

Bearings That Lube for Less
. The self-lubricating properties of oilimpregnated PM bearings also provide design flexibility. As the temperature of the bearing rises in service, the oil releases, creating a cushion between the shaft and the bearing surfaces. When rotation of the shaft or bearing stops and the bearing cools, it again absorbs

What Does Self-Lubrication Mean?
Q: "What Does Self-Lubrication Mean? A: For Polygon's PolyLubeTM fiber-series self-lubricating bearing, a proprietary form of PTFE is used. In the form PTFE is used in the PolyLubeTM fiber series bearings, lubrication occurs via the film transfer process. As the shaft rotates under normal cycling

Bearing Cost
. The very minimum maintenance cost is associated with self-lubricating bearings -- provided they deliver sufficient service life. Replacement costs: These costs depend more on the specific design than on the type of bearing. In general, however, sliding bearings are replaced more easily than

Lubricating Low Profile Conveyors
, and operates at only 70% of the R.P.M. of these needle bearing units to produce the same belt speed. The lubrication limitation on needle bearings, plus the lack of axial load capacity, and self-aligning ability to contend with miss-alignment and shaft deflection, appears to make them a less desirable

Sintered-metal self-lubricating bearings are based on powder-metallurgy technology. They are economical, suitable for high production rates and can be manufactured to precision tolerances. General properties of porous-metal bearing materials have been described in Machine Design magazine (Vol. 54

Choosing the Right Bearing Shaft Material
in between a bearing and its mating surface, both can suffer from increased wear. Dirt, dust and paper fibers are just some elements that can cause problems. Self-lubricating bearings can eliminate this issue because no grease or oil are on the bearing. This means dirt particles cannot penetrate as easily
