Are these claims true? Seems Frelon is a good bearing material.
An expanded series of 148 Frelon lined linear bearings from Quality Bearings & Components can tolerate upto 1,500 psi over the portion of the bearing that is carrying the load. These Frelon lined anodized aluminium bearings carry 4 to 8 times the load of ball bearings. 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. |
