Boca MX Engine bearings

The Boca Bearing Company have announced the launch of the new MX Engine bearings for radio controlled engines. As radio controlled engines have evolved they have become more powerful, use more nitro fuel and come under greater thrust loads, than in the past. The nitro content can dry the thin, stock bearing retainer very quickly which makes the whole bearing susceptible to premature failure when subjected to high radial and thrust loads. Boca Bearing is introducing the MX Bearing line to solve these specific issues. MX bearings have a unique, new internal design to increase load capabilities, which allows the bearings to work under harsher operations where shafts come under excessive side and radial load. These bearings are available in both a standard high-speed version with either chrome steel balls or races or as a ceramic hybrid, with ceramic balls and chrome races. Chrome steel is used because it is harder than stainless steel but the races are also cryogenically processed to attain an even harder surface. A stronger, thicker retainer material has been used to allow the MX Bearings to hold up under high nitro content fuel and Grade 10 balls are used to give a closer tolerance to enhance performance.
