Description

Linear Rail Model HG – Sliding Rail, Linear Guide

HGR15 – 4 Meter

• Sliding rails and linear guides are machine tool components characterized by their long, rail-like structure.
• They feature a rectangular block that acts as the load-bearing element, such as HGH, HGW, or SBR types.
• Linear rails are available in various sizes and lengths to suit different application requirements.
• They offer high strength, durability, and ease of installation.
• Linear rails are versatile and can be applied in diverse fields, including photocopiers, CNC machines, the automotive industry, and the textile industry, among others.

1. 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.

2. 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.

1. Place the slider parallel to the guide rail
2. Gently push the slider into the guide rail
3. The slider slides into the guide rail
4. The installation is over, without dropping the steel ball

When installing, do not remove the plastic retainers from the slider in advance, as this may cause the steel balls to fall out during assembly, preventing normal installation and use. When disassembling, the retainers should cooperate with the disassembly process to prevent the balls from dropping.

3. High-Speed Motion with Low Driving Force

Because linear guideways have minimal friction resistance, only a small driving force is required to move a load. This results in significant power savings, particularly in the moving components of a system and especially for reciprocating parts.

4. Long Life with High Motion Accuracy

With a traditional slide, accuracy errors can arise from the oil film’s counterflow. Insufficient lubrication leads to wear between contact surfaces, progressively degrading accuracy. In contrast, rolling contact exhibits minimal wear, enabling machines to achieve a long operational life with highly precise motion.

5. High Positional Accuracy

When a load is driven by a linear motion guideway, the frictional contact between the load and the machine bed is rolling contact. The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and static coefficients of friction is minimal. Consequently, slippage is prevented while the load is in motion.

6. Equal Loading Capacity in All Directions

Due to their specialized design, these linear guideways can accommodate loads in both vertical and horizontal directions. Conventional linear slides have limited load capacity in directions parallel to the contact surface and are more susceptible to accuracy degradation when subjected to loads.
