HIWIN MG Series Miniature Linear Guideway

FEATURE

MG
The MG Series with tiny and light weight design is suitable for miniature equipment. All materials are special grade of stainless steel and alloy steel for anti-corrosion ability. Gothic arch contact design has high rigidity and accuracy characteristic in all directions. Steel balls are constrained by miniature retainer so without loosing balls when remove the block MG Series. The design of enlarged width, MGW Series, has increased capacity of moment load. Gothic arch contact design has high rigidity characteristic in all directions. Steel balls are constrained by miniature retainer so without loosing balls when removing the block away from the rail. All metal components are made of stainless steel for anti-corrosion ability.

MG-O
The MG-O recirculation system uses integrated design, the recirculation part is made by resin. Reduced about 20% weight. This design can reach smoother motion performance. Block, rail and stainless components such as ball and retainer, which provides excellent resistance to corrosion. Small and light weight makes MG-O suitable for miniaturized machinery. MG-O series can be used in many fields, such as semiconductor equipment, robotics, measuring equipment, office automation equipment, and the other slider machinery. MG-O is suitable for limited space installation.

APPLICATIONS

Semiconductor equipments、PCB assembly equipments、Medical equipments、Robots、Precision measuring equipments、Office automation equipments、Other miniature sliding mechanism

Model Number of MG Series

MG Series linear guideway can be classified into non-interchangeable and interchangeable types, which are the same size.The interchangeable type is more convenient due to replaceable rails; however, the precision is less than non-interchangeable type. With strict dimension and quality control, the interchangeable type linear guideways are a suitable choice for customers when rails don’t need to be paired. The model number contains information for the size, type, accuracy, preload, and so on.
