new series of 28 Frelon lined plain and flanged sleeve bearings from Sterling Instrument (an ISO 90001 manufacturer) can tolerate up to 1,500 psi over the portion of the bearing that is carrying the load. A 1/2" I.D. Frelon bearing will carry as much load as a 1" I.D. ball bearing. Long service life for these self-lubricated bearings is another major benefit. Although wear rates are affected by surface finish, shaft hardness, length of travel, contamination and lubrication, these bearings last on average 4 to 8 times longer than ball bearings. The Frelon liner material is designed to replace oilite and plastic materials. It is impervious to most industrial chemicals and acids. Surrounding the Frelon is a 6061 Aluminum housing
