The Roller Flange Linear Guide combines the ultra high rigidity of rollers with the high anti overturning ability of flange installation, making it an ideal choice for heavy duty machine tool sleepers, large automated welding equipment, and heavy duty truss manipulators. The Hualong HRG flange type guide rail adopts a square flange structure, with through hole threads or countersunk holes on both sides of the slider, which can be locked from the bottom or countersunk installed from the top, especially suitable for downward tilting and large overturning moments. This series is based on the DB45 ° 45 ° combination design, with rollers and raceways in line contact. By increasing the number of rollers, each column can have up to 16 rolling elements, achieving extremely low elastic deformation and maintaining spindle stability under heavy loads. The width of the guide rail covers 35 to 65mm, and standard lengths within 4000mm are available in stock. Non standard lengths can be extended up to 6 meters.

A linear motion block (also called linear guide slider) is a core component paired with linear guides in mechanical systems which equipped with internal rolling elements (e.g., steel balls, rollers) to reduce friction for low noise and smooth operation.
Cnc linear guide is essential for precise automation and provides low-friction linear motion by fixed rail and roller-equipped slider. And optimized design minimizes wear, maintains accurate positioning, and supports heavy loads.
1. HRG CC stands for standard length slider: suitable for conventional heavy loads, such as gantry crossbeams and floor boring and milling machine slides.
2. HRG HC stands for elongated slider: the total length of the slider increases, the roller column becomes longer, and the rigidity and lifespan are further improved. The total length of the slider is about 8 16mm longer than the standard type.
HRG flange type accuracy grades are available in H, P, SP, and UP. Pre pressing options include Z0, ZA, and ZB.
Product advantages and features
1. Minor deformation under heavy load: The elastic deformation of the roller line contact and dense rolling elements is only 1/5 of that of the same size ball guide. The measured HRG CC runs at 120 m/min for 15000 kilometers without peeling.
2. Double locking of flange surface: The slider is equipped with mounting ears on both sides, which can be installed from the top or bottom to adapt to different bed structures, such as inverted crossbeams and downward tilting slide seats.
3. Strengthen the chip scraping system: Equipped with metal scraper and rubber wiper as standard, it can effectively remove high temperature iron chips, welding slag, and chip fluid.
4. High rigidity preloading: Provides ZB heavy preloading from 0.12C to 0.14C to increase the system resonance frequency, suitable for high dynamic response scenarios such as high speed gantry machining.
5. Interchangeability design: The slider can be replaced separately and is compatible with mounting dimensions from mainstream brands such as THK and INA of the same specifications.
6. Optional self lubricating E2: E2 self lubrication module can be used without centralized oil supply, suitable for heavy duty applications at high altitudes or in clean rooms.
Our highlights of linear guides
01
Four directional equal load：The HGH, HEG, and HWE series adopt a four column circular arc groove design, which can simultaneously withstand loads in four directions: up, down, left, and right, meeting the requirements of complex working conditions.
02
Automatic heart adjustment function：Combination design DF45 ° 45 °, steel ball elastic deformation can absorb small deviations on the installation surface, reduce assembly difficulty, and improve operation stability.
03
High rigidity structure：The HRG roller series adopts a linear contact design, with minimal elastic deformation and a 300% increase in rigidity; The HGH series can apply preloading to further enhance rigidity.
04
Interchangeability design：The slider and guide rail can be replaced separately, without the need for paired grinding, reducing maintenance costs by more than 50% and significantly reducing downtime.
05
Multi dust prevention system：Provide options such as oil scraper, metal scraper, double layer oil scraper, and upper dust cover to adapt to harsh environments such as dust and high temperature iron filings.
06
Self lubrication option：Optional lubrication module, no need for centralized lubrication of oil pipes, reducing oil pollution, suitable for clean rooms and high environmental requirements scenarios.
After sales service
1. Warranty period: 1 year of product warranty service is provided from the date of shipment. We provide free repair or replacement of parts for quality issues caused by non human factors during the warranty period. After the product is tested and confirmed, if there are damaged guide rails or sliders, they can be returned for a refund, or we can send a new product for free. Beyond the warranty period, spare parts and repairs will still be provided at cost price.
2. Installation guidance service: Based on your actual needs, remote video guidance or on site installation guidance services can be provided. Technical engineers can view installation steps, torque locking, and other details in real time through videos to ensure that the installation accuracy of the guide rail meets the μ m level standard. If purchasing in bulk or high precision equipment, engineers can be dispatched to the site for full guidance.
3. Calibration and accuracy testing: After the installation of the guide rail is completed, technical personnel can be arranged to conduct on site operation debugging and accuracy retesting, and provide debugging reports to ensure that the equipment reaches the design accuracy before being put into production.
4. Maintenance services: During the warranty period, a free equipment inspection can be arranged once a year to check the operation status of the guide rail, wear of the oil scraper, and aging of the lubricating grease, and to issue a maintenance report. At the same time, free assistance can be provided to develop annual maintenance plans based on operating conditions.
5. Troubleshooting and emergency support: Provide a 48 hour fault response commitment after the customer reports a repair, a remote solution will be provided within 24 hours for general problems, and an engineer will be present within 48 hours for problems that require on site handling. In emergency situations, temporary spare parts can be prioritized for customer installation and production before returning faulty parts to minimize downtime losses.
6. Spare parts supply and old parts repair: Commonly used spare parts are in stock and can be shipped at any time. Damaged guide rails can be returned to the manufacturer for evaluation. If they still have repair value after testing, paid repair services such as straightening, re grinding of the raceway, and replacement of rolling elements can be provided, with costs much lower than purchasing new products.
7. Accessory replacement service: We provide a single purchase channel for worn accessories such as oil scraper blades, metal scraper blades, dust sheets, etc., without the need to replace the entire slider, reducing maintenance costs.
FAQ
Q1: Can it be used for vertical installation (Z axis)?
A1: Yes, it is possible, but consideration needs to be given to the flow of lubricating grease. It is recommended to install a lateral oil nozzle.
Q2: Do you need to pair it (one guide rail with two sliders)?
A2: A single guide rail can be paired with multiple sliders without mandatory pairing. But under heavy load, it is recommended to use two or more sliders to distribute the load.
Q3: Is the flange countersunk hole a through hole?
A3: Default threaded hole; Customization of through hole and nut installation is possible, but drawings are required.
Q4: Can flange guide rails be mixed with square sliders?
A4: The guide rail is universal, but the height of the slider is different, which requires re checking the height of the bearing surface.
