🛡️ Shielded Miniature Bearing - Uxcell 5mm x 9mm x 3mm Review

Bought for my 3D printer extruder. I haven't had a chance to use them yet, but I always keep them in my spares kit when I need them. Arrived quickly and were very cheap.

I used these bearings to make four band saw blade guide blocks with bearings at the point of contact and they work great! Having just made them I can't confirm their durability but they appear to be well made with no wobble at all.

They appear sleek and well made. However, I will not use them in high-speed applications. Like other people, they were used to fix the horrible Crosman trigger in some airgun models. I started with a stock 8x5x2.5. The trigger was much better, but I felt it could be improved. I ordered this 9x5x3mm and the trigger is great now. I tested the solution by hitting the buttocks on the ground and couldn't get it to casually fire. So this seems like a safe solution. This made the cheap airgun more…
