Thus, HG series linear guideways can achieve a long life with high speed, high accuracy, and smooth linear motion. The HG collection linear guideways are on hand in two types: flange type and square type. The flange type is suitable for heavy moment load application because of the low assembly height and larger mounting surface. They additionally offer a wide range of stroke lengths to accommodate many applications ranging from unique positioning to high speed movement. The HG series also features self-aligning capability to absorb installation error. In addition, both flange and square types are available. The flange type is recommended for heavy moment load application, while the square type offers extra mounting flexibility. HG Series linear guideways are designed with load capacity and tension greater than other similar products with circular-arc groove and structure optimization. The HG Series linear guideway has equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to take in installation-error. The HG Series linear guideway achieves a long life with high speed, high accuracy and smooth linear motion. The HG series is available in two types of flange, or rectangular mounting surfaces. The flange type is suitable for heavy moment load application.

It is a four-row single arc tooth contact linear guide, and integrates the heavy load precision linear guide with optimal structure design, which improves the load and rigidity ability compared with other linear guides. With four directions and other load features, and automatic aligning function, can absorb the mounting surface assembly error, get high precision demands.

Linear guide rail is a groove or ridge made of metal or other materials, which can withstand, fix and guide the moving device or equipment and reduce its friction. A longitudinal groove or ridge on the surface used for guiding, securing computing device parts, specific equipment, instruments, etc. Guide rail, additionally recognised as slide rail, linear guide rail, linear slide rail, used for linear reciprocating action occasions, has a greater load ranking than linear bearings, and can bear a certain torque, can achieve high precision linear motion in the case of high load.

HGH HGW MGN EGW EGH series delivers high smoothness, high rigidity and high durability. With sturdy dust-proof design, prevents abnormal chips getting into the blocks and rails,extending service life, making relevant to contaminative environment.

This linear guide block EGH15CA is EC series, it 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 take in installation error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length make the EG series greater suitable for high-speed, automation machines and applications the place space is limited. The retainer is designed to hold the balls in the block even when it is eliminated from the rail.

Kairun offeres two type blocks of flange type and square type, 15 mm Medium load (SA) square type block EGH15SAZAC block mounting from top, these linear blocks can install with the EGR15R or EGR15U (large mounting hole M4*16 and mouting from top)linear guide rail. the rail lenght can supply1000 mm to 4000mm each piece. also if wants the length of extra than 4000mm, we can provide the joint sevice to meet your request.

The design of the EG 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 take in installation-error, allowing for greater accuracies. Additionally, the decrease assembly height and the shorter length make the EG 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.

Block types
OUR offers two types of linear guideways, flange and rectangular types.



Features of EG Series
The design of the EG series offers a low profile, high load capacity, and high rigidity. It additionally elements an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation machines and applications the place space is limited.
The retainer is designed to hold the balls in the block even when it is eliminated from the rail.



Accuracy
The accuracy of the EG series can be classified into 5 classes: normal(C), high(H), precision(p), super precision(sp), and ultra precision(Up). Choose the classification by referencing the accuracy of selected equipment.



Mounting location
The standard location of the grease fitting is at both ends of the block, the nipple can also be set up in the aspect or top of the block. for lateral installation, we recommend that the nipple be mounted to the non-reference side, in any other case please contact us. When lubricating from above, in the recess for the O-ring, a smaller, preformed recess can be found. preheat the 0.8 mm diameter steel tip. Carefully open the small recess with the metal tip and pierce through it. Insert a round sealing ring into the recess. (The spherical sealing ring is not supplied with the block) Do now not open the small recess with a drill bit this may additionally introduce the danger of contamination. It is possible to carry out the lubrication by using the oil-piping joint.

The design of the EG series offers a low profile, high load capacity, and high rigidity. It also features an equal load ranking in all four directions and self-aligning capability to absorb installation-error, allowing for greater accuracies. Additionally, the lower assembly height and the shorter size make the EG series more suitable for high-speed, automation machines and applications where space is limited. The retainer is designed to preserve the balls in the block even when it is removed from the rail.

Linear slide rail is a kind of rolling guide, it is composed of metal ball between slide block and the slide rail for the endless scroll circulation, make the load platform can easily along the slide rail with high precision linear motion, the coefficient of friction can be decreased to 1/50 of the usual sliding guide, make it can easily reach mu m class location accuracy.Between slide block and the slide rail making yuan at the stop of the design, make the linear slide rail can be under the direction of the up and down or so and so on various load at the same time, the recycling of patent system and streamlined structure design makes linear slide rail with greater easy and low noise.se.

The HG series linear guides are four-row single-arc tooth-type contact linear guides. They integrate super-heavy-load precision linear courses with an optimized shape design. Compared to other four-row linear guides of the same type, the load and stress capacities are increased by more than 30%. With four-direction load characteristics and an automatic centering function, these guides can absorb assembly errors of the mounting surface and achieve high-precision requirements. The HGH20CA linear rail block can be added or substituted on an HGR20 rail. These rails are used for high-load applications where accurate and smooth operation is required. They come with a plastic spacer to keep the balls from falling out and a grease nipple.
