Needle Roller Bearing - 1.2500 in Bore, 1.7500 in OD, 1.2500 in Width, Open
QTY QUOTEKOYO NRB - KOYO NRB HJ-202820
One-piece channel-shaped outer ring of bearing quality steel, heat-treated to provide maximum load rating
Integral end flanges provide axial location for the needle rollers
Bores of the end flanges serve as piloting surfaces for the cage, locating it to prevent removal of the lubricant film on the raceway
These bearings have a steel cage which provides inward retention for the needle rollers
The design assures roller stability and minimizes friction between the cage and the needle rollers
The needle rollers are made from high carbon chrome steel, through-hardened, ground and lapped to close tolerance with controlled contour for optimum load distribution
Unsealed closure
