ABB IRB 6620 - Expected Component Life

3.2.3 Expected component life
General
The expected life of a specific component of the robot can vary greatly depending
on how hard it is run.

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
Depending on application, the lifetime can vary. The Service Information System (SIS) that is
integrated in the robot software can be used as guidance when planning gearbox service for the
individual robot. This applies to gearboxes on axes 1, 2, 3 and 6. The lifetime of gearbox axes 4
and 5 is not calculated by SIS (See the Operating manual - Service Information System). In some
applications, such as Foundry or Washing, the robot can be exposed to chemicals, high temperature
or humidity, which can have an effect on the lifetime of the gearboxes. Contact the local ABB
Robotics Service team for more information.
The SIS for an IRC5 system is described in the Operating manual - Service Information System.
