Replacement Bearing for John Deere GX21510, GX20818

The bearings fit well and according to my calipers are exact, they perform well and if you keep them greased (as you should) they will last as much as the OEM, you can change ALL the bearings for what it costs to change 2 at the dealership.

did not realize my old bearings were that bad until I replaced them. The mower runs much smoother and quieter now.

The replacement bearing fit perfectly. It performs as should be expected. Another post stated he didn't like the replacement bearing. As long as the housing isn't damaged, it will fit. If I am in need of additional bearings, I will purchase another. The shipping time was also outstanding. I had the replacement bearing within 4 days of purchase.

Fit perfect. Appear to be high quality. Mine were the fully sealed bearings. If your spindle has grease zerk, I'd get the ones with seals on only one side. My spindles had no grease zerk so I didn't see the point in putting in the greasable bearings.Will update if the bearings fail prematurely.

worked great had no problems with them and they got here very fast i am very happy with this product

A bearing. Have not used. Size is as described

This should be relisted with the correct description. The bearings are not what are pictured.

Bearings fit nicely and as expected, the top Bearing fit was very snug, but installation was achieved using a Rubber Hammer to seat it in place! Blades now run smoothly with very little Vibration! Can't ask for a better Replacement Part for the Price!
