Standard Spherical Roller Bearings

At QM Bearings we believe that just because something is labeled as standard doesn't mean it has to be ordinary. Similar to the unique design considerations given to our Blue Brute housed bearing units, our NEW 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, the NEW Blue Brute standard sphericals will withstand any test you throw at them.

Blue Brute bearings standard double-row spherical roller bearings features:

	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

The world class standard we use in engineering our Blue Brute Standard 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.
