Ideal for use in exposed locations where protection from dust, dirt, water, or other foreign matter is required. The balls are retained between two hardened steel races banded together by a mild steel or brass sleeve on the outside diameter. V grooved raceways on this bearing enable it to carry radial loads equal to 25% of its thrust load capacity, while decreasing the amount of friction created by a full contact round groove design. Typically has more balls per bearing, thus providing greater thrust capacity than a 3 piece retained style bearing of similar dimensions.
