One of the training events I had last week was a familiarization class with high-fidelity EVA hardware (see Logbook L-405).
Among many other things, we had a chance to practice applying lubricant to the snares of the robotic end effector. You can check out this older Logbook for some pictures of the actual end effector and target pins in space:
When we squeeze the trigger to capture the target pin, it’s important that the snares rotate freely at their attachment points when they close. And so periodically spacewalkers need to take a grease gun out and apply some lubricant to the snare bearings themselves.
