Standard solid Big Axle rollers are designed around three working parts
The outer wheel/roller features a 27% greater wall size for less harmonic distortion and better tracking of the cam lobe
Pin bearings are decreased in size by 12%, which increases RPM for more precise tracking
Axle size is increased 36% and doubles as the inner race, so the pin bearing and complete roller assembly rotates around the axle instead of an inner race, eliminating all possible movement in and around the axle
