cnc linear rail MGN 7C MGN 7H linear guide bearing

Metal linear bearing is a low-cost production of linear motion system for unlimited travel with the cylinder axis. Since the ball bearing point contact with the shaft, so use the load is small. Minimal friction ball rotation, thereby to obtain smooth movement precision. Plastic linear bearings are self-lubricating properties of a linear motion system, the biggest difference is that the metal in the metal linear bearings linear bearings are rolling friction, is the point contact between the bearing and the cylinder axis, so this suited for low load speed movement; while plastic linear bearings are sliding friction is between the bearing surface contact with the cylinder axis, so this low-speed movement for high loads.

The MG series is a miniature linear guideway that comes in a compact size with a Gothic arch contact design that offers high stiffness and high rigidity against moment loads in all directions. The MG series also offers anti-corrosion protection which all material is in a special grade of stainless steel for compatibility in various working environments. The MG series is available in a narrow block type (MGN) and also with an enlarged width (MGW).

1. Tiny and light weight, suitable for miniature equipment.
2. All materials for block and rail, including rolling balls and ball retainers, are in special grade of stainless steel for anti-corrosion purpose.
3. Gothic arch contact design can sustain loads from all directions and offer high rigidity and high accuracy.
4. Steel balls will be held by miniature retainer to avoid balls from falling out even when the blocks are removed from the rail installation.
5. Interchangeable types are available in certain precision grades.
