Introduction
The HGR20 linear guide rail is the standard specification of the HGR series, continuing the core advantages of high load capacity and smooth operation. It combines wear resistance and durability with low noise characteristics, has wide adaptability, and is easy to maintain, making it a linear motion solution that balances performance and practicality.
Product Parameters
This series continues the core structural design of the series, using special bearing steel material with surface protection treatment, offering excellent hardness and durability. It features a built-in ball retainer and circulation system, combined with a four-point contact design to ensure stability under multi-directional forces. It has low-friction and low-noise operational characteristics, with reliable positioning accuracy. It adopts standardized mounting reference surfaces and pre-drilled hole designs for wide compatibility, and also supports convenient maintenance of the lubrication system with good interchangeability.
Core Advantages
1. The HGR20 linear guide rail inherits the heavy-load design gene from its series, with excellent rigidity. Even under high-speed operation or complex load conditions, it can maintain stable motion accuracy without issues like displacement or vibration.
2. Made of carefully selected specialty bearing steel, processed with strict heat treatment and surface protection, it offers both high hardness and wear resistance, ensuring stable performance in harsh environments such as humidity and dust.
3. Equipped with a built-in efficient ball circulation system and retainer structure, it prevents collisions between balls and further reduces friction resistance, resulting in quiet and smooth operation without unnecessary noise.
4. Designed with standardized mounting reference surfaces, it can accommodate various slider specifications and flexibly integrate with different equipment assembly requirements, offering strong compatibility and adaptability.
5. The overall structure is simple and easy to maintain. Routine lubrication is enough to continuously maintain good performance, making long-term usage convenient and effortless.
Scope of Application:
With high rigidity, high precision, and heavy load-bearing capacity, HGR rails are widely suitable for various industrial scenarios. They can be used in automated production lines and conveyor equipment to ensure smooth and efficient material transfer, and are compatible with machine tools, machining centers, grinders, lathes, and other types of machine equipment.

FAQ
1.Q: How to prevent steel balls from falling out when disassembling the slider of an HGR rail?
A: This series of rail sliders is equipped with a steel ball retainer. When disassembling, the slider should be pulled out parallel and smoothly along the rail without tilting or prying. If complete separation is required, a special auxiliary tool can be used to support the bottom of the slider to prevent the retainer from deforming, thus preventing steel balls from falling out.
2. Q: What are the key points to pay attention to when extending the HGR rail?
A: When extending, prioritize using rails from the same batch to ensure dimensional consistency. The ends to be joined should be aligned with a thermal expansion gap of 0.03–0.05mm. After installation, check the straightness with a straightedge to ensure an error of ≤0.01mm per 100mm. Additionally, the mounting holes should be staggered to avoid affecting the smooth operation of the slider.
3. Q: Is it necessary to choose linear guides from the same batch when using multiple rails?
A: It is recommended to prioritize using products from the same batch. Linear guides from the same batch have higher consistency in machining accuracy and dimensional tolerances, which can reduce fitting errors during parallel installation. If this is not possible, you should check the key dimensions of each rail in advance, such as width and height, to ensure deviations are within the allowable range and avoid uneven resistance during slider movement due to dimensional differences.
4. Q: Can linear guides be used in harsh environments?
A: Some specialized models can. For harsh environments such as dust, moisture, and corrosion, you can choose linear guides with dust seals, stainless steel materials, or surface anti-corrosion coatings, along with accessories like dust covers and scrapers to prevent debris from entering the raceways or parts from rusting.
