Product Description

IKC SKF BC1 roller bearings
Green Flag Karting now offers SKF BC1 roller bearings for all applications that require 6205 bearings.
This bearing is a roller style main bearing for most KZ engines. It will last much longer, allow more RPM and add power to your engine.
 Karting innovation by SKF Racing: a special roller bearing derived from the bearings tested in GP engines, specifically designed as a crankshaft main bearing for kart engines. Infact this bearing is a direct replacement for the 6205, C4 class bearings used in most shifter 125 cc engines available on the market (dimensions 25 x 52 x 15 mm), having mounting tolerances designed in such a way that once installed it has the same radial play. 
The BC1 bearing is not a stock roller 6205 bearing but a special unit that, thanks to a special design of the rollers, races and innovative split inner ring, is specifically made for the kind of working conditions that happen in a modern racing 2 stroke engine. There are multiple advantages resulting from this design, including:
at least 2 times more load carrying capacity;
bearing life extended from 2 up to 3 times respect the ball bearings normally used;
higher stiffness;
reduced friction;
and in some cases the consequent better mechanical efficiency leads to a measurable performance improvement. If you want to know more about the BC1 bearing you can  the official SKF Racing brochure in English. SKF part number: BC1-1442B
