Single Row Deep Groove Ball Bearings

Single Row Deep Groove Ball Bearings

Equivalent dynamic bearing load

For single bearings and paired bearings arranged in tandem

P = Fr   when Fa/Fr = e
P = XFr + YFa   when Fa/Fr > e

The factors e and Y depend on the relationship f0 Fa/C0, where f0 is a calculation factor, see product data, Fa the axial component of the load and C0 the basic static load rating.

In addition, the factors are influenced by the magnitude of the radial internal clearance; increased clearance enables heavier axial loads to be supported. For bearings mounted with the usual fits as listed in tables T1, T5 and T6, the values for e, X and Y are listed in table 5. If a clearance greater than Normal is chosen because a reduction in clearance is expected in operation, the values given under "Normal clearance" should be used.

For bearing pairs arranged in tandem, Fr and Fa are the forces acting on the bearing pair.

For bearing pairs arranged back-to-back or face-to-face

P = Fr + Y1Fa   when Fa/Fr = e
P = 0,75 Fr + Y2Fa   when Fa/Fr > e

If the bearings are mounted with the usual fits as listed in tables T1, T5 and T6, the values for e, Y1 and Y2 are listed in table 6. Fr and Fa are the forces acting on the bearing pair.
