SC20UU Linear Bearing for Ø20mm Shaft
The SC20UU linear bearing , is a bearing with block of aluminum, used for displacement of this by a rod or axis of 20mm.
The assembly is formed by an aluminum block, with a linear roller bearing in its interior (LM20UU). The block is provided with 4 holes for anchoring in a plate or base.
It is widely used, as a linear bearing, to move the Z axis without looseness in CNC machines,
When replacing the roller bearing (LM20UU), it is only necessary to remove the clamping flanges from the bearing and remove it from the aluminum block.
No maintenance required.
In the photo you can see a practical application, used in this case in the MakerCNC milling machine.
