Letool10pcs 625ZZ Ball Bearing PA66 Nylon coated U Groove pulley wheel roller 5X26X13mm bearing

The dimensions of the bearings I received matched the dimensions shown in the diagram to as high of a precision as my instruments could measure (+/- 0.02mm). There were no visual defects and the items matched the pictures in the listing. The bearing turned smoothly and did not seem to have any slop. The bearing was very securely fastened to the nylon housing.

Exactly as described and working smoothly.

Perfect for my diy double sheave deck organizer.
