4.2.3 Expected component life
Expected life depends on usage
The expected life of a specific component of the robot can vary greatly depending
on how hard it is run.
Expected component life
Note Expected life Component
40,000 hours
ii
Cable harness, normal us-
age
i
20,000 hours
ii
Cable harness, extreme us-
age
iii
The SIS system is decribed
in
Operating manual - Ser-
vice Information System .
40,000 hours Gearboxes
40,000 hours
iv
Balancing device
i
Examples of "normal usage" in regard to movement: most material handling applications and limited
use of bending backwards mode of axis 3.
ii
Severe chemical or thermal environments, or similar environments, can result in shortened life
expectancy.
iii
Examples of "extreme usage" in regard to movement: press tending, very severe palletizing
applications, major use of axis 1 movement and major use of bending backwards of axis 3.
iv The given life for the balancing device is based on a test cycle of 4,000,000 cycles that starts from
the initial position and goes to maximum extension, and back. Deviations from this cycle will result
in differences in expected life!
