Linear rolling guide: widely used in electronics, laser, engraving, 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.
The new HG Types from Hiwin features a roller as the rolling element instead of steel balls. The roller series offers super high
rigidity and very high load capacities. The HG Types is designed with a 45-degree angle of contact. Elastic deformation of the
linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load
directions.The HG series linear guideway offers high performance for high-precision manufacturing and achieving longer service

(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.
Q：What is trapezoidal screw?A：Trapezoidal screw is a kind of lead screw. It is a trapezoidal screw thread. Generall, a 30-degree trapezoidal screw means that the angle of the thread section extension is 30 degrees. Trapezoidal screws are divided into left-handed, right-handed and bi-directional-handRead More
What are the advantages of linear modules? The linear module is an automatic transmission element, which uses timing belt or ball screw to drive the slider to move. It is usually composed of timing belt, ball screw, direct moving die, aluminum alloy profiles, ball screw bracket, coupling, motor, PhoRead More
We all know that linear guides are now an important part of mechanical equipment. Be careful when using linear guides. Many factors will affect the guides and make them fail during operation! Today I will introduce you to the influence of temperature on linear guides! The influence of temperature oRead More
The relationship between the pre-pressure of the ball screw and the load of the screw is mainly used for gap adjustment. If high precision is required, the pre-pressure should be increased accordingly, but it should not be too large, otherwise it will cause high temperature and reduced efficiency.Read More
What is the ball screw drive torque? How should this torque be calculated? The torque of the mechanical components is called the driving torque of the ball screw. The ball screw will produce a certain degree of torsional deformation under the action of torque. Torque is the basic load form of transmRead More
Features of Rotating SeriesZero clearance in spline rotation direction/high positioning accuracyThe contact angle between the nut and the steel ball is 40°, and the bearing DB type (back-to-back combination) design is adopted. Due to the wide span between the effective centers of the bead groove, thRead More
