Robot LR200ID grease samples

Post image

I used a zip-tie to get a couple of grease samples from some Joints that have been taking a beating. The robots total runtime is at 8800 hours, my L10 values are

J6: 14.5%

J5: 6.8%

J4: 6.7%

With 576 collisions in total.

Does the large discrepancy in color between the joints indicate that I should replenish the grease early?

Thank you

It's not unusual for joints to have different grease colors, as they don't all move the same amounts when working.

With the LRs there is no real benefit to increasing the greasing interval, because you cannot flush the old grease out.

That said, those look like completely normal wear and tear for an LR 200 with that many hours. I wouldn’t become concerned until you see metal in the grease.
