The UC209 ball bearing can mount Φ45mm shaft diameter. It uses a popular set screw locking mechanism and is suggested for industrial and agricultural applications where normal loads are encountered. Bearing is prelubricated and ready for immediate installation. The wide inner ring provides effective shaft support for a broad range of applications. The positive contact of the land-riding bonded nitrile seal helps protect against harmful contaminants and retains lubricant under severe operating conditions. An external steel flinger provides additional protection from contamination. The UC-series features smooth running and low noise operation. It also has spherical outside diameters for use in housings with corresponding spherical inside surfaces to compensate for shaft misalignment. Made in china.
