  • Control Engineers Guide to Applying Linear Bearings

    Shaft Hardness and Linear Bearing Life . Bearing life is usually expressed as the number of hours an individual bearing will operate before the first evidence of metal fatigue develops. The usual life rating for industrial applications is called “L-10” life. The L-10 life is the number of hours in service that 90% of the bearings will survive.
