Abstract
A cylindrical roller bearing has inner and outer rings, cylindrical rollers, and a retainer having a pair of annular members positioned close to and disposed along the opposite ends of the cylindrical rollers provided in a circular arrangement within the annular space between the inner ring and the outer ring. The annular members of the retainer are provided with cantilever projections each positioned at a radially outward portion of each space between adjacent rollers in opposed relation to beam portions connecting the annular members with the projections extending between the peripheral end surfaces of the adjacent rollers for retaining the rollers in pockets formed by the annular members and the beam portions.
