Introduction
The HGH20 linear rail is a cost-effective precision transmission component in the field of industrial automation. Relying on a four-row single-arc tooth contact structure, it achieves balanced force in the radial, reverse-radial, and lateral directions, significantly enhancing load capacity and structural rigidity. Its built-in automatic centering function can compensate for installation errors, and with its rolling friction design, not only does it have a friction coefficient far lower than traditional sliding guides, but it can also easily achieve micrometer-level positioning accuracy, meeting the stringent requirements of precision machining and automated production lines.
Product Specifications
HGH20 This series covers multiple models and sizes, supports custom lengths, is equipped with various precision and preload levels, offers four-way balanced load capacity, has interchangeable slider guides, and is easy to maintain.
Core Advantages of HGH20 Linear RAI:
1. The HGH20 linear RAI features a four-row single-arc tooth contact structure, providing balanced radial, reverse radial, and lateral forces. Its load capacity and rigidity far exceed similar products, ensuring stable transmission even under heavy-load, high-frequency conditions.
2. With built-in automatic alignment, it compensates for installation errors. Coupled with rolling friction design, it operates smoothly with low resistance, easily achieving micron-level precise positioning, meeting the stringent requirements of precision equipment.
3. The slider and guide rail are precisely controlled in size and are directly interchangeable. The ball retainer prevents rolling element dropout, and scrap plates can be replaced without disassembling the slider, significantly simplifying maintenance procedures.
4. Made from selected bearing steel with anti-corrosion treatment, the sealed and dust-proof structure effectively resists dust and moisture. High-speed operation is stable and low-noise, maintaining high-precision transmission performance over long-term use.
5. Supports optional various precision and preload levels. The guide rail length can be flexibly customized, suitable for precision machining, automated production lines, and other industrial scenarios, with convenient integration.
Applications: CNC machining centers, machine tools, precision processing machines, heavy cutting machines, large marble cutting machines, grinders, injection molding machines, punch presses, automated devices, transportation equipment, measurement instruments.

FAQ
1. Q: What is the most likely cause of abnormal noise when HGH20 is running?
A: If the noise is uniform, it may be due to insufficient or degraded grease. Simply add the suitable NLGI grade 2 lithium-based grease. If the noise is sharp and harsh, it is often caused by iron filings or other debris mixed into the raceway. In this case, you need to disassemble the slider, clean the raceway with anhydrous ethanol, check the steel balls for damage, and replace any damaged steel balls promptly.
2. Q: What inspections should be done when reusing HGH20 after long-term idle?
A: First, remove the moisture-proof packaging and clean the dust off the guide rail surface with a soft brush, then wipe it clean with anhydrous ethanol. Next, check whether the seals are intact, and if the anti-rust oil has dried up, reapply it. Then manually push the slider back and forth to ensure there is no sticking. Finally, apply grease and run the slider a few times without load before putting it into operation.
3. Q: How should oil leakage from the HGH20 slider be handled?
A: First, check whether the dual-lip seal on the slider is damaged, as this is a common cause of leakage. If damaged, promptly replace it with a seal of the same specification. If the seal is intact, the issue may be over-lubrication. In this case, move the slider back and forth to expel excess grease, and control the grease amount in future lubrication so that it only fills the raceway.
4. Q: Can HGH20 adapt to extreme high or low-temperature conditions?
A: Yes, but special measures are required. In low-temperature environments below -20°C, a dedicated low-temperature HG series grease should be used. For high-temperature conditions above 60°C, use high-temperature-resistant seals made of fluororubber, shorten the lubrication cycle, and use cooling devices if necessary to prevent components from aging due to high temperatures.
