Perfect replacement bearings for Pflueger Trion TRI30 Spinning Reel
Used these rubber sealed bearings to replace the original bearings that had seized up in my Plueger Trion TRI30 spinning reel. Reel works better than when new, bearings are smooth and a perfect fit replacement.

Perfect fit for my Daiwa fishing reels
These are a perfect fit for the bearings used in Daiwa reels. Since they were so cheap, I bought just to try, and now I have 9 spares for the next time it fails. They fit perfectly and are smooth turning, just like what came with the reel. I fish a lot and go through bearings about every 2 years.

Fits a arrma big rock as wheel bearings
Cheaper than arrma and look the same. I can make these last a long time with pulling bearing rubber side cover off and soak them with a zoom spout oiler - aka electric motor oil. I can get up to 3 seasons out of them.

Smooth…work well
I installed these in a power wheels gearbox. Used 1 for each gearbox. Used on 1st gear. Smallest gear. Plastic gear was melting on metal shaft so I installed these bearings. They work well.

Right size and smooth bearing
Bought for steering linkage on Arrma Kraton 6s v5 to replace the brass bushings. Perfect fit at a great price. These coupled with an adjustable servo saver offer much smoother and precise steering.

Perfect fit for Kyosho Turbo Scorpion
Needed to replace hub and upright bearings on a Turbo Scorpion. These fit perfectly, they looked identical to the ones that came with the original kit.
