Heavy Load rail of  linear guide GH Series

GH series linear guid rail are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, GH series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.

Features:

1. Self-aligning capability:

By design, the circular-arc groove has contact points at 45 degrees. GH series can absorb most installation errors due to surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements and the shift of contact points. self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation.

2. Interchangeability

Because of precision dimensional control, the dimensional tolerance of GH series can be kept in a reasonable range, which means that any blocks and any rails in a specific series can be used together while maintaining dimensional tolerance. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.

3. High rigidity in all four directions

Because of the four-row design, the GH series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway allowing large permissible loads and high rigidity.

Construction of GH Series:

Rolling circulation system: Block, Rail, End Cap and Retainer

Lubrication system: Grease Nipple and piping Joint

Dust protection system: End seal, Bottom seal, Bolt Cap, Double seals and scraper

Applications:

Automatic equipment

Grinding machines

Heavy cutting machines Machining centers

High speed transfer device

Injection molding machine

Machine tools

Marble cutting machines

Precision machining machines

Punching machines

Model Number of GH Series

GH series guideways can be classified into non-interchangeable and interchangeable types. The sizes are identical. The only difference between the two types is that the nterchangeable type of blocks and rails can be freely exchanged, and their accuracy can reach up to p class. The model number of GH series contains the size, type, accuracy class, preload class, etc..

Types

(1) Block types

SHAC offers two types of linear guideway which are flange and square types. Because of the low assembly height and larger mounting surface, the flange type is suitable for heavy moment load application.

(2) Rail types

Besides the standard top mounting type, SHAC also offers the bottom mounting type of rails to customers.

Accuracy Classes

The accuracy of GH series can be classified into normal (C), high (H), precision (P), super precision (AP), ultra precision (UP), five classes. please choose the class by referring the accuracy of applied equipment. At present, our normal accuracy is C.

Advantages and Features of Linear Guideway

1.High positional accuracy

When a load is driven by a linear motion guideway, the frictional contact between the load and the bed desk is rolling contact. The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving.

2.Long life with high motion accuracy

With a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear; therefore, machines can achieve a long life with highly accurate motion.

3. High speed motion is possible with a low driving force

Because linear guideways have little friction resistance, only a small driving force is needed to move a load. This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts.

4. Equal loading capacity in all directions

With this special design, these linear guideways can take loads in either the vertical or horizontal directions. Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more likely to become inaccurate when they are subjected to these loads.

5. Easy installation

Installing a linear guideway is fairly easy. Grinding or milling the machine surface, following the recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion.

6. Easy lubrication

With a traditional sliding system, insufficient lubrication causes wear on the contact surfaces. Also, it can be quite difficult to supply sufficient lubrication to the contact surfaces because finding an appropriate lubrication point is not very easy. With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centralized oil lubrication system by piping the lubrication oil to the piping joint.

7. Interchangeability

Compared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. for high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.Our linear guideway interchangeable with HIWIN.
