AOSN application-engineered lubrication seriesSpecial Lubrication Series
Self-Lubricating Cylindrical Roller Bearings
A maintenance-reduced option engineered around the operating environment, using an application-specific lubricant, cage and lubricant-retention configuration.
Lubrication matched to duty
Grease or oil system is selected according to load, speed, temperature and service interval.
Maintenance-reduced design
Retention and sealing options can help extend lubrication intervals; final performance is application-dependent.
Engineering confirmation
Send the existing designation and operating data so AOSN can confirm cage, clearance and lubricant compatibility.
Different from Solid Oil BearingsThis subseries uses an application-engineered lubrication package. Solid-oil construction remains a separate AOSN product family.
