Boca Bearing (www.bocabearings.com), the first company to introduce ceramic bearings to the hobby world and the world’s innovative leader in RC engine bearings, has launched the expanded portfolio of its latest MX Engine bearings, specifically for radio controlled engines.

With the evolution of RC engines, they now come under greater thrusts loads than before and are using more nitro fuel. The nitro fuel quickly dries the thin stock bearing retainer, making the whole bearing vulnerable to premature failure when subjected to heavy radial and thrust loads. With the introduction of the expanded portfolio of MX Bearing, this particular issue will no longer be a problem.

The company’s MX bearings offers a new and unique internal design that increases load capabilities and enables the bearings to function even under extreme operations, where shafts are exposed to excessive radial and side load.

The MX bearings come in both as a ceramic hybrid, with chrome races and ceramic balls, or as a standard high-speed version featuring chrome steel balls or races. The races are cryogenically processed to achieve a harder surface, while the chrome steel is utilized since it is harder than stainless steel. To enable the bearings to withstand high nitro content fuel, the company used a thicker and stronger retainer material for this new portfolio. Moreover, Grade 10 balls have also been used to provide a closer tolerance to optimized performance.

Aimed at engines with known stock bearing issues, the new line of MX Bearing is currently offered in a limited size range. The company has specifically developed the MX Engine bearings to deliver extended life and increased speed to RC engines.

Meanwhile, Boca Bearing offers an additional discount on all MX Engine Bearings kit. Complete bearing kit is now available for engines such as OS, Sirio, and Picco.
