Zenoah K603406001 Bearing 12x28x8mm for G200,G231,G240,G260,G270,G290  [K603406001]

12x28x8mm ball bearing for small RC engines

This Zenoah K603406001 is a 12x28x8mm ball bearing intended for use in RC-scale engine and rotating assemblies. It fits the G-series engine models listed in the product title and serves as a direct replacement bearing to restore smooth rotational movement and reduce friction where worn bearings affect performance.

Installation notes: remove the old bearing cleanly to avoid debris entering the crankcase or gearbox, press the new bearing evenly into its housing without tilting, and check axle/trunnion alignment before final assembly. A light, RC-appropriate lubricant can be applied sparingly to rolling elements during reassembly to aid initial break-in.

Tuning and maintenance role: replacing a worn 12x28x8mm bearing helps maintain consistent rotational behavior in small Zenoah engines, reduces heat from friction under load, and can prevent premature wear of adjacent seals and shafts when installed correctly.
