Product Description

1

  • Linear motion bearings provide freedom of movement in a single direction.
  • Often used in conjunction with cylindrical shaft or rail.
  • The steel ball is in point contact with the shaft and rotates with very little frictional resistance, so as to obtain smooth movement with high precision.

Linear Ball Bearing Motion Slide Units

  1. Grease may be applied prior to use to improve smoothness.
  2. Maintain lubrication of optical shafts and guides during operation.
  3. The recommended load is 80% of the rated load, exceeding the rated load will affect fluidity.
  4. The table needs to be level during installation, otherwise it will interfere with installation calibration.
  5. Require regular cleaning and maintenance.

I purchased these to replace grinding bearings in my sliding miter saw, they are longer than my stock bearings but I think it honestly help provide more stability. They slide very smooth, better than stock, and function exactly as expected. No more noise and jerky motion while sliding and at a way lower price than purchasing a new saw.

Bearings were great right out of the box. No problems. Used them on a 10mm linear shaft for a 3D printer. Been working ever since

These bearings are very gritty and do not roll smoothly especially if there is any weight on them. Feels like a car driving over rumble strips. Would not buy again. Already ordered some IKO Bearings from Japan

Not bad compared to a different brand I recently bought. These slid easily on the 12mm rails I bought. One of them was gritty and probably won't use it

Used to rebuild small CNC machine. These have outlasted the original.

Had some noisy bearings on sv06+. Bought both 4 of these and 4 of Aopin. Not sure if it was just luck but the Aopin felt far smoothe and were much quieter. 1 of 4 of these had a slight clunky feel when moving on rod. 2 of 4 felt sloppy, I could wiggle them slightly back and forth on the rod. I ended up using 1. The other 3 will work in a pinch. Or I want to build a lower res printer. But I'll likely just buy more of the other brand for 50 cents or so more.

I purchased these for a flight simulator throttle upgrade, and they have been perfect. I wiped them down a little bit before use because they were quite oily; but, after that they have been perfect!

My first impression was that the surface finish was very nicely machined. That kind of told me tha the rest was nothing to worry about. The shipping and delivery, once again was timely and professional which always makes me happy!
