Life Calculation

The relationship between the basic rated life of the bearing, the basic dynamic load rating, and the equivalent dynamic load can be expressed by equation (4.1). When the bearing unit is used at a constant rotating speed, it is more convenient to express the lifespan in hours as shown in equation (4.2).

Cast iron square flange mount unit UCF Rated Lifespan Calculation

Here,
L₁₀: basic rating lifespan, 10⁶ rotations
L_10h: basic rating lifespan, hr
C_r: Basic dynamic load rating, N
P_r: Dynamic equivalent load, N (see 5 Bearing Load)
n: Rotational Speed, min^-1
