Everything you can see on them is stainless. As for the bearings inside, I don’t know, never had one go bad and my oldest ones are at least 3 years old and exposed to all the weather. They are hardiest I have ever used. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great part at a great price *by L***E on October 10, 2025* Great product for a great price.
