Products Description
Flanged Linear Guide Rail System | Hualong Machinery
In modern industrial automation, linear guides are the core and key components that ensure the accuracy and tolerance stability of equipment operation. For CNC engraving machine, milling machine manufacturers, automotive assembly, semiconductor equipment, and logistics automation integration, Hualong's flange type linear guide rail system has mature and stable performance, high cost effectiveness, and is a high quality substitute for high end imported guide rails. The load bearing structure of ordinary standard guide rails is limited, and there are strict requirements for benchmark alignment during installation; Hualong adopts a four column Gothic arch 45 ° contact design, which can achieve balanced rated loads in radial, anti radial, and transverse directions without sacrificing overall performance. It supports horizontal, vertical, inverted, and side mounted installation in all directions, suitable for various complex working condition layouts.
Features
Four directional equal load capacity
The Hualong linear guide rail system adopts a 45 ° Gothic arch contact structure, equipped with four rows of steel balls, to achieve radial, anti radial, left and right lateral equal rated load design. A symmetrical and balanced structure, without the need to recheck load parameters due to changes in installation posture, and without worrying about reduced lifespan. The guide rail supports any installation method, including horizontal, vertical, inverted, and sidewall installation. In order to cope with the constantly changing gravity direction and cutting force of multi axis equipment, relying on the omnidirectional equal load characteristic can simplify the layout design of guide rails without deliberately using paired guide rail configurations, effectively optimizing the cost and installation space of the entire machine accessories.
Easy to install self aligning design
Surface misalignment during installation is one of the most common and expensive error issues in linear guide rail systems. Even if the parallelism error between two tracks is only a few micrometers, it can lead to uneven distribution of ball loads or premature wear, and even cause operational lag and other issues.
The Hualong linear guide rail systems adopts an elastic deformation self alignment mechanism, which utilizes the flexible structure of the rail body to absorb small installation errors, effectively avoiding contact stress concentration and local abnormal point contact problems caused by assembly deviations. By using this design, installation time can be greatly reduced by 40%, eliminating the need for high precision manual scraping and grinding when installing reference surfaces and support pads, as well as manual grinding to micrometer level flatness.
Anti fall fixing system
When repairing or replacing parts, traditional guide rails are prone to the problem of steel balls scattering and falling off after the slider separates from the guide rail body.
Hualong adopts a unique locking ball structure design with a built in plastic auxiliary bracket, which can firmly lock all steel balls in the circulation circuit even if the slider and guide rail are completely separated.
This anti fall function can prevent pollution damage, avoid the trouble of reloading individual balls, save the tedious operation of manually reinstalling steel balls one by one, greatly shorten equipment maintenance downtime, and compress maintenance time from hours to minutes. Hualong's linear guide rail system, combined with double lip end sealing and integrated dust removal structure, can maintain reliable operation in dusty workshop environments, machining centers exposed to coolant, and outdoor logistics facilities for a long time.
Precautions for installation of linear guide rail
When installing linear guides, do not remove the slider unless necessary. If you need to remove or install the slider from the guide rail, please use the included clamp rail.
When installing linear guides, do not arbitrarily swap the sliders of non interchangeable guides to avoid affecting accuracy.
When installing the linear guide rail, please use a torque wrench and follow our company's recommended torque to lock the bolts in sequence to ensure the straightness of the guide rail.
The advantages of our linear guide rail
Complete system delivery
Unlike suppliers who sell guide rails and sliders separately, Hualong adopts a factory assembly mode to achieve interchangeability of the entire series of products of the same model. Any slider of the same model can adapt to any guide rail of the same model, greatly simplifying spare parts selection and inventory management.
P4 precision steel ball
All circulating balls meet the G10 P4 precision level standard, providing smooth, low friction motion with a friction coefficient as low as 0.005, only one fiftieth of that of ordinary sliding rails. This reduces the size requirements of the motor and can accommodate smaller motor sizes, effectively reducing energy consumption under high reciprocating conditions. It is widely applicable to high speed cycling applications, such as picking and placing robotic arms and packaging production lines.
Multiple series covering all operating conditions
Hualong ball bearing flange linear guide offers three product series: HGH standard type, HEG high load type, and HWE wide type.
The load bearing capacity of each slider ranges from 100kg to 6000kg, making it fully suitable for various application scenarios such as lightweight precision equipment, automated production lines, and heavy duty CNC machine tools.
Global Performance Strength
Hualong has been focusing on the field of linear motion technology since 1997, and has obtained a total of 81 national patents, including 41 core invention patents. Our products are exported to over 200 countries and regions. All batches of products undergo strict processes such as continuous operation testing and precision inspection before leaving the factory to ensure consistency in factory quality.
