RMS C4 racing main crankshaft bearings and seal kit for Yamaha Aerox, BWS, Jog R/RR, Neos & Slider/ Minarelli 50cc 2-stroke engines.
Kit contains two SKF bearings and two double lipped oil seals; this is a very high quality C4 bearing (same as used for Polini Evolution) offering less friction due to the polymer cage and less engine damage in the event of failure.
Suitable for use with high revving, high power racing 70-95cc cylinders kits as well as standard 50cc cylinders.
Bearing dimensions: 20x47x14mm (6204 C4)
Oil seal dimensions: 20x30/33,5x5,3x6
Oil seal dimensions: 20x42/43x8x9
NOTE: For polymer bearings with the half-open cage, bearings must be inserted so that the cage is facing the crankcases. (balls visible)
