HGW-CC Series Linear Guideways for Linear Motion

HGW-CC Series Linear Guideways for Linear Motion,Small friction loss and high transmission efficiency. Linear guides, also known as linear guides, slides, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. It is called linear guide in the mainland, and generally called linear guide or linear slide in Taiwan.
Linear rolling guide: widely used in electronics, laser, engraving, Punching machines、Marble cutting machines、Automatic equipments、Grinding machines、High speed transfer equipments cutting and other industries, with high precision, low noise, corrosion resistance, rust resistance, high speed, low cost, etc., is favored in the field of linear transmission.

Specification :
HG 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 interchangeable type of blocks and rails can be freely exchanged, and their accuracy can reach up to P class. The model number of HG series contains the size, type, accuracy class, preload class, etc..

Key Features :

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

Interchangeability
Because of precision dimensional control, the dimensional tolerance of HG 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 dimensionaltolerance. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.

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

Advantages :

(1) Optimal design
FEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion.

(2) Super high rigidity
The RG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller guideway features higher load capacity and greater rigidity.

(3) Super high load capacity
With the four rows of rollers arranged at a contact angle of 45-degrees, the RG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The RG series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.

(4) Operating life increased
Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore, stress concentration was reduced siginificantly and the RG series offers longer running life. The nominal life of RG series can be calculated by using Eq.
