This isn’t a normal use for bearings. I had to replace a bearing in my Celestron NexStar 8SE telescope, and these handled the mount’s weight and movement perfectly.
The bearings are highly durable — solid construction, smooth rotation, and no wobble or backlash. For their price, the quality is excellent.
I’m impressed with how well they withstood real telescope use. If you need reliable, sturdy bearings at an affordable price, these are an excellent choice — even in applications they weren’t originally intended for.
Great bearings
This is not my first order, and far from my last. Fast Eddy Bearings are always smooth and always reliable!!
These Clutch Bell Bearings are fantastic for any Nitro Clutch. I usually get a few races on each set prior to needing replaced. This also includes my qualifier runs as well. I highly recommend using these as I have never ran into any issues like other bearings I have used.
