Nominal life L10=(C/P)3 [5x104m]

where:

L10 - nominal life, expressed as multiplicity of value 5x104m (50 km) the movement of shaft or slide bearing, or reciprocating travel. This is a life the correspond to 90% reliability, possible to achieve under the conventional working conditions, workmanships and used materials.

C - specific dynamic capacity of a bearings [N] is loading, that can be transmitted by slide bearings, with nominal life 5 x 104 m.

P - dynamic equivalent load of linear bearings [N]; this is a value of the force that is acting on linear bearings under the conventional working conditions.
