NSK Bearings CYLINDRICAL ROLLER BEARING NSK NU-309-M
NSK Cylindrical Roller Bearings are available with a patented high strength cage design in pressed steel, machined brass or polyamide. Special materials are available for more arduous applications. Cylindrical bearings offer low noise and low heat generation and by virtue of the line contact between rolling elements and raceways, have high radial load capacity which are suited for high-speed applications.

Precision ground inner ring provides a hardened raceway for the rollers when used with an unhardened shaft. The ring contains an oil hole and annular groove for relubrication of the bearing and can be used with both CAGEROL® and GUIDEROL® bearings or can be utilized as a bushing in plain bearing applications.

Gates® Power Transmission Hi-Power® II C153 Banded Heavy Duty V-Belt, C Section, 7/8 in W Top, 157 in L Outside, 17/32 in THK, EPDM
The wrapped classical section Hi-Power™ V-belt has a long reputation for reliability on agricultural and industrial applications. The arched top of the Hi-Power belt provides superior strength to prevent "dishing" and distortion of the tensile section. The cords are properly aligned, each of them carrying its full share of the load.
