T-100 Branded Thurst Bearings
This enclosed style series offers protection from dust, dirt, water and foreign matter. The balls are retained between two hardened steel races banded together by a mild steel or brass sleeve on the outside diameter. The "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. The banded style of the T-100 series typically allows more balls per bearing, thus providing greater thrust capacity than a 3 piece retained style bearing of similar dimensions.
