Manufactured by a well established and specialist British bearing supplier who have been making these Bigends for many years - this particular Bigend is of modified 'Caged Roller' design - more suited to high performance than the original Crowded Roller type. Comes complete with BigEnd nuts.
The overall dimensions of this Bigend are as per the original - so can be fitted to standard crankshafts without any modification - but like SOHC engines, they have rollers running in a cage - which means they are less likely to rub and overheat. They are more suited to an OHV engine that is being used for prolonged high speed usage or performance events. (However - do not forget: OHV and SV engines were originally fitted with Cast Iron flywheels - not steel flywheels like the OHC engines, therefore you still need to bear this in mind - from my own experiences racing OHV engines, I know the flywheels are often the limiting factor!).
These BigEnds come supplied 'hot dipped' in protective grease as per photograph, as a complete assembled unit and include the Bigend Nuts as well.
A typical OHV mid-1950's crankshaft is shown in the second photo (this being from a 600cc Model 19) - but this Bigend is of the type fitted to all OHV and SV models from the 1930's to the late 1950's - i.e: Model 18, ES2, Model 19, 500T, Model 50 (350cc), 16H and Big 4.
