Plastic linear bearings SKS
Maintenance-free SKS linear bearings have special patented surface design which is designed for dry operation. The patented design allows the bearing to be used in the critical conditions such as in containment and dust environments.
The spiral grooves of the bearings allow the containments and dust to enter the grooves, but also be brought out of the bearing system. Usually, traditional ball bearings will be blocked by the containments which can cause a breakout of the bearing.
