Why is cycloidal follower best suited in high-speed applications?

The cycloidal cam profile is best suited for high-speed applications because the successive derivatives of the function, ie. velocity, acceleration, and jerk are continuous functions rather than step functions, throughout the motion. Due to this continuity the bearings of the cam and follower are least prone to cyclic stresses, This improves the service life and no noise is present.

Thanks to all for the explanation.

Thank you all for the explanation.

Because cycloidal motion has uniform rise and return.

From the diagram of acceleration and angular displacement of cam, acceleration becomes zero when there is maximum velocity which smoothens motion in the high-velocity rise.
