Pillow Blocks Have Self-lubricating, Aluminum Bearings
A new series of 54 pillow blocks from Sterling Instrument (an ISO 9001 manufacturer) feature Frelon® lined Anodized Aluminum bearings which 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.
The self-aligning bearings, identified as the S61P_C and S61P_Z Series, are stocked in precision and standard bore tolerances and in inch and metric sizes. They are designed to fit shafts that range from .250" to 1.25" and from 8 to 30 mm. Open and closed models with both precision and standard tolerances are available.
