The Boca Bearing Company is pleased to announce the launch of their new MX Engine bearings for radio controlled engines. For the past 20 years Boca Bearing has been one of the most innovative leaders in the RC engine bearing field and among the first to offer ceramic bearings to the hobby world. With the introduction of their new MX Engine Bearings, Boca Bearing is raising the bar even further for particularly problematic RC 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. This 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.
The MX Bearing line is currently available in a limited size range aimed at those engines with known stock bearing issues. Boca Bearing's MX Engine Bearings are made to give increased speed and extended life. For a limited time Boca Bearing will be offering an additional $10 discount on all MX bearing kits. Full bearing kits are available for engines such as Nova Rossi 12/15/21/28 size engines, OS 15/18/21/25/30 size engines, Picco 15/21/27 sized engines, Collari, Sirio and more.
