These are going to be harder than the arms. Our original idea was to make them softer so the bushings would wear more than the arms but some of these planter arms are already using material we felt we couldn't get softer than and keep them dependable. These are not a hardened bushing.


I think that's the best plan. With that indexing pin in the bushing that attaches to the arm, it's not going to move against the arm. Without those pieces moving against each other, wear is going to be negligible regardless of hardness.

Is there a lubrication recommendation to these? The original bushings are said to be oil-impregnated, but in actual practice I have seen them to benefit from additional lubrication.
