NTN F2-1 Bearing

load on bearings operating under such conditions can be converted to a mean load (Fm), this is a load which gives bearings the same life they would have under constant operating conditions. (1) Fluctuating stepped load. The mean bearing load, Fm, for stepped loads is calculated from formula (2.2). F1 , F2 . Fn are the. The NSK bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. The inside construction of the ball bearing for the
