319262B Double Row Cylindrical Roller Bearing 319262B Road roller bearing E3-252
Product Description
Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rollingelements. They can therefore be used in appliexcavatorions involving heavy radial and impact loading.
The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitablefor appliexcavatorions that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.
