5Maintenance and Inspection
Table 5-5 ： Lubrication specifications
The grease nipple position is shown in Fig. 5-6 . The lubrication specifications for each place are shown in Fig. 5-6
［Caution］
・ The brands of grease given in
Table 5-5 are those filled when the robot is shipped.
・ The lubrication time is a cumulative value of the operation at the maximum speed. If the operation has been
suspended, or if the designated speed is slow, the lubrication time can be lengthened in proportion.
(The "Lubrication interval " in
Table 5-5 is usually based on the three-year inspection. 8Hr x 20 days x 36
months = 6000Hr.）
・ Depending on the robot operation state, the lubrication time will fluctuate, so determine the time according to
the state so that the grease does not run out.
・ With the maintenance forecast function of the personal computer support software (option), the guidance of
lubrication time is calculated according to the operating environment of the customer.
・ The numbers in the correspond to the supply positions in Fig. 5-6 .
・Avoid excessive lubrication since it may lead to grease leak. Also, the number of lubrications is limited to 3 times.
