spherical roller bearings feature a self aligning design for supporting high radial loads and heavy axial loads in both directions. each bearing consists of an inner ring with two raceways and an outer ring.
the raceways in these bearings are positioned off center to handle angular (combined radial and thrust) loads.. double row bearings handle thrust loads in both directions.. open bearings dissipate heat more efficiently than shielded and sealed bearings.. shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
each features hardened steel construction, which helps to offer long service life. they are also suitable for use where needle roller bearings must be combined with wider inner rings in order to allow larger axial shaft displacement in relation to housing. the optimum running surfaces are required for seal lips.
