The recommended load is 80% of the rated load. Exceeding the rated load will affect the fluidity.

The workbench must be kept level during installation, otherwise it will interfere with the installation and calibration.

Please carefully wipe the anti-rust oil and seal the lubricant before use.

Please avoid mixing lubricants with different properties.

Linear motion bearings provide freedom of movement in a single direction.

Linear Motion Bearings Provide Freedom Of Movement In a Single Direction

It can obtain a stable linear motion with high sensitivity and high precision, which is used for the use of linear stroke with cylindrical shaft or guide rail.

Since the load-bearing ball is in point contact with the bearing jacket, the steel ball rolls with the least frictional resistance. Therefore, the linear bearing has low friction and is relatively stable. It does not change with the bearing speed, and can achieve smooth linear motion with high sensitivity and high accuracy.

Ordered a 4 pack of these and of uxcell because the price was very similar. I got the uxcell a day before and they set a pretty low bar. Then these came and they felt to have more oil inside the bag. They were very quiet and slid great. Nice tight tolerance on the rod. I know they are not for rotary application. But the balls even slid very nicely when rotated in either direction. Where the other brand, as well as the bearings pulled off my printer would not they would catch pretty hard and lock up. Will very likely buy more to replace the rest of my stock bearings.

These run like roller skates on a gravel road I assume they are made with Square bearings instead of ball bearings

El producto está todo bien pero hice un pedido con varios artículos del mismo proveedor y por alguna razón hicieron 3 envíos con diferentes fechas de entrega en lugar de uno solo.
