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.

FEATURE

The new RG series from Hiwin features a roller as the rolling element instead of steel balls. The roller series offerssuper high rigidity and very high load capacities. The RG series is designed with a 45-degree angle of contact. Elasticdeformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higherload capacities in all 4 load directions.The RG series linear guideway offers high performance for high-precisionmanufacturing and achieving longer service life.

Optimal design

FEM analysis was performed to determinethe optimal structure of the block and therail. The unique design of the circulation pathallows the RG series linear guideway to offersmoother linear motion.

Super high rigidity

The RG series is a type of linear guideway that uses rollers asthe rolling elements. Rollers have a greater contact area thanballs so that the roller guideway features higher load capacityand greater rigidity. The figure shows the rigidity of a rollerand a ball with equal volume.

Super high load capacity

With the four rows of rollers arranged at a contact angle of45-degrees, the RG series linear guideway has equal loadratings in the radial, reverse radial and lateral directions. TheRG series has a higher load capacity in a smaller size thanconventional, ball-type linear guideways.

Operating life increased

Compare with the ball element, the contact pressure ofrolling element is distributed on the line region. Therefore,stress concentration was reduced siginificantly and the RGseries offers longer running life. The nominal life of RG seriescan be calculated by using Eq.
