Upgrade Stainless Steel  Front bearing for Nitro Engine OS 40-50-61-91-105,it fits Also other models, if you not sure, please contact us.

Stainless Steel bearings are made from heat hardened 440C stainless bearing stock.  This steel is hardened to well within the requirements for standard steel bearings.  Since it is a heat hardened stainless, it is magnetic!  It is actually referred to a corrosion resistant steel so tiny rust spots can appear on it but usually not enough to affect performance.  If you had rust issues with standard bearings, these will all but eliminate that problem

Those bearings are a direct upgrade to stock bearing delivered with OS engines. Bearing comes with 2 Rubber Shields/sealings. 1 should be removed in order to allow Oil to pass throw, this side is the Inner side, Outer side stays with Sealing.
