Thanks, I have measured the remnants of the bearing, its 5x13x4 (IDxODxL).
How do find out those codes like 625ZZ ?
Going purely by size there are many options on ebay, but I'm unsure how to know it's good enough for the job, would prefer to buy a bearing intended for such motors to be sure, or maybe buy one on ebay with a known bearing brand from Australia.
Still concerned whether the old bearings died from high speed so want a bearing that can definately handle the 11.1v batteries motor speed.
Any advice here?
