OS 55 Hyper Stainless Steel Bearings
RCBearings heli bearings are high quality alternatives to expensive OEM part number bearings. Made to exacting tolerances, you can expect a long, trouble-free life at a fraction of the cost. Our bearings are made from either AISI 52100 bearing steel or corrosion resistant 440C stainless steel and front bearings come with non contact shields.
NOTE: All heli engines above .35ci should use a rear bearing with a high speed plastic retainer! We source our retainers from Japanese manufacturers that make the best. There used to be almost daily postings on heli forums of pictures of destroyed engines due to retainer failures. That is until OS and Thunder Tiger went to plastic retainers! Beware of other sellers that try to pass off cheap standard bearings for your expensive heli engine!
If your engine isn't listed, call our Technical Support line and we will see if we can make up a set for you. We have over 400 different bearing types in stock and thousands more available.
We only sell premium industrial grade bearings with most being ABEC-3 or better. We never sell cheaper hobby-grade bearings! Our bearings are used in such products as museum art reproduction printers, underwater propulsion systems, hotrod manufacturers, military wind tunnel testing, semiconductor manufacturing, commercial printers and world-class competition model aircraft. We have partnered with several manufacturers for over twenty years to produce bearings to meet or exceed our customers exacting requirements.
