Table 5-5 ： Lubrication specifications
The grease nipple position is shown in Fig. 5-9. The lubrication specifications for each place are shown in Table 5-
5.
［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 sus
-
pended, 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 2-year inspection. 8Hr x 20 days x 24 months =
4000Hr.）
・ 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.
・ The numbers in the Table 5-5 correspond to the supply positions in Fig. 5-9.
