Commercial/Industrial Spherical Bearings
The sixteen series of Aurora spherical bearings all incorporate the single-piece race type construction, providing excellent ball-to-race conformity and structural integrity, along with the advantages of metal-to-metal contact between bearing components. Standard race materials are low carbon, heat treated alloy or stainless steel. Balls are precision ground alloy or stainless steel. Metal on metal race units can be re-lubricated through an annular groove in the outer race with two interconnecting holes positioned at 180 degrees, while a self-lubricating PTFE to metal interface may also be optionally specified in many series. Inch or imperial sizes range from 3/16 inch through 6 inch bore, metrics from 3 through 160 mm. In addition to catalog offerings, non-standard materials substitutions and dimensional modifications are possible, to meet specific customer application requirements.
Aurora Bearing Company produces over a dozen lines of inch dimension spherical bearings. All series, from the economy, light section fractured race GEZ series through the high performance PNB and PWB series feature precision ground heat treated alloy steel balls, and one-piece steel raceway construction. Race materials include low carbon, and heat treated alloy or stainless steels.
Aurora Bearing Company produces three lines of metric spherical bearings. All feature one-piece steel raceways for maximum structural integrity. Aurora COM-M series bearings are available in sizes from 3mm to 30mm and follow the dimensions of DIN 648 schedule K. Light section fractured race GE series are available in sizes from 12 through 160 mm. Metal on metal race units can be re-lubricated through an annular groove in the outer race with two interconnecting holes positioned at 180 degrees, while a self lubricating PTFE to metal interface may also be optionally specified.
