Service Life-millions of inches (mm)
Service Life Estimate Assumptions:
• Sufficient quality and quantity of lubrication is maintained throughout service life (please refer to engineering reference on page 212 for lubrication interval estimates.)
• Bearing and screw temperature between 20° C and 40° C
• No mechanical hard stops (external or internal) or impact loads
• No external side loads
• Does not apply to short stroke, high frequency applications such as fatigue testing or short stroke, high force applications such as pressing. (For information on
calculating estimating life for unique applications please refer to the engineering reference on page 212.)
