Perfect for Fishing Reels

Used these S695Z bearings on my saltwater fishing reel. They spin smoothly and show no signs of rust after several trips. Highly recommend for marine applications.

Good Value for Money

Overall great bearings. One out of the ten was slightly tighter than the others, but still usable. Fast shipping and good packaging.
