SC20UU / LM20UU - 20mm Linear Bearing in Housing

Closed linear bearings are widely used in linear motion technique.
The outer jacket is made of bearing steel. The middle part of the bearing is made of plastic.
They are perfect for use in dirty industrial conditions because they have a rubber seal, which prevents various types of filings or dirt from entering the bearing.

Linear ball bearings are one of the most basic and important elements of the linear motion technique. The structure itself, as well as their high strength and longevity, is undoubtedly a unique achievement of technology.

Product features

The bearings have a rubber seal on both sides, thanks to which no dirt of any kind accumulates on the bearing tracks.
The bearing with the platform allows for convenient assembly.
They achieve very high precision and speed of movement.
There are mounting holes at the top and bottom, allowing for easy adjustment and calibration of the bearing in the device with M4 screws.
Linear bearing inserts used in the LM standard are replaceable.
