standard spherical roller bearings are a product of looking to the customer to find their most pressing concerns and needs. As a result of our commitment to the highest quality and engineering standards and our attention to details with features like the black-oxide inner race, 
Industry standard 222 bearing series
Black-oxide inner ring for superior corrosion resistance
Super finished rollers and raceways for smooth quiet running
Self-Aligning spherical rollers allow for a total of 3° of misalignment
C-3 clearance on all standard bearings
World-class design provides high load carrying capacity

Spherical Roller Bearings are also evident in our adapter sleeves. We know our customers are concerned with quickness and reliability, and the precise engineering and machines of our adapter sleeves translates into faster bearing installation and secure fit on the shaft. Conforming to both ISO 298201:1995 (metric sizes) and ANSI/ABMA Std. 8.2 (inch dimensions) specifications, these adapter sleeves, with a taper of 1:12, come complete with both the locking nut and locking device.

Tests show that, under most corrosive conditions, our black oxide coating outperforms other coating solutions. To us, this means black-oxide is a standard feature. To you, this means less down time removing rusted and corroded adapter sleeves and more bearing uptime.
