brief introduction of this kind of radial ball bearings
618/619/160 series radial ball bearings a kind of thin section bearings, the major design constraints are space, weight and load.
They are available with metal shields (ZZ) or rubber seals (2RS).
The available bore dimension range from 10mm to 1500mm. these thin section ball bearings also belong to deep groove ball bearings, which is the most common type in rolling bearing. It is usually composed of an outer ring, an inner ring, a row of steel balls and cage. It mainly bears radial loads, but it can also bear a small amount of axial loads. Axial carrying capacity will increase when selecting large radial clearance. The contact angle is zero when bear only radial force; the contact angle will more than zero when axial force is acted.
