If you would like to purchase linear guideways and fortunately, we have the honor to be your choice, then this article is especially for you.

This is all about how to choose the types of custom less friction linear guideways of LIMON.

LIMON linear guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using re-circulating rolling elements between the rail and the block, the load platform can easily move linearly with high precision along the slide rail. Compared to a traditional slide, the coefficient of friction for a linear guideway is only 1/50. With these features, linear guideways can greatly enhance moving accuracy, especially, when accompanied with precise ball screws.

 

LIMON offers a variety of linear guide rail series, each with different sizes, load capacity, precision and more other option.

 

 

Custom Less Friction Linear Guideways - Heave Load Type Linear Guideways – H series

Applicable industries of H series:

Grinding, Milling and Drilling machine, Lathe, Electric discharge machine, Wire cutting machine, Wood cutting machine,Precision measure equipment, Machine center


 

  • Self-aligning capability

By design, the circular-arc groove has contact points at 45 degrees. H 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.

  • Interchangeability

Because of precision dimensional control, the dimensional tolerance of H 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.

  • High rigidity in all four directions

Because of the four-row design, the H 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.

 

 

Custom Less Friction Linear Guideways - Low Profile Type Linear Guideways – E series

Applicable industries of E series:

Automatic equipment, Semiconductor equipment, Laser engraving machine, High speed transfer machine,Packing machine,Medical equipment


 

The design of the E series offers a low profile, high load capacity, and high rigidity. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracy. Additionally, the lower assembly height and the shorter length make the E series more suitable for high-speed, automation machines and applications where space is limited.

The retainer is designed to hold the balls in the block even when it is removed from the rail.

 

 

Custom Less Friction Linear Guideways – Quiet Type Linear Guideways – QH/QE series

Applicable industries of QE/QH series:

High precision measure equipment, Semiconductor equipment, Automatic equipment, can be widely applied in high-tech industry required high speed, low noise, low dust generation.


 

  • Low Noise Design

With SynchMotion technology, rolling elements are interposed between the partitions of SynchMotion to provide improved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced.

  • Self-Lubricant Design

The partition is a grouping of hollow ring-like structures formed with a through hole to facilitate circulation of the lubricant. Because of the special lubrication path design, the lubricant of the partition storage space can be refilled. Therefore, the frequency of lubricant refilling can be decreased. This is linear guideway is pre-lubricated. Performance testing at a 0.2C (basic dynamic load) shows that after running 4,000km no damage was apparent to either the rolling elements or the raceway.

  • Smooth Movement

In standard linear guideways, rolling elements on the load side of the guide block begin rolling and push their way through the raceway. When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QH linear guideway, with SynchMotion technology prevents this condition. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to prevent contact with one another thus keeping the element's kinetic energy extremely stable in order to effectively reduce fluctuations in rolling resistance.

  • High Speed Performance

This kind of series offers excellent high-speed performance due to the partitions of the SynchMotion structure. They are employed to separate the adjacent balls thereby resulting in low rolling traction and the metallic friction between adjacent balls is eliminated.

 

 

Custom Less Friction Linear Guideways - High Rigidity Roller Type Linear Guideways – R series

Applicable industries of R series:

CNC machining centers,Heavy duty cutting machine,CNC grinding machine


 

  • 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 R series linear guideway to offer smoother linear motion.

  • Super high rigidity

The R 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. The figure shows the rigidity of a roller and a ball with equal volume.

  • Super high load capacity

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

  • 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 significantly and the R series offers longer running life. The nominal life of R series can be calculated by using Eq.
