ball bearing carriages and guide rails are the core products of Lishui Hengyuan Bearing Manufacturing Co., Ltd., designed specifically for high-precision and high-speed industrial automation equipment. Using high-quality bearing steel and alloy steel materials, through precision grinding, hardening treatment, and multiple sealing processes, the linear motion performance of low friction, high rigidity, and long service life is achieved. As the golden combination of precision transmission systems, rails are compatible with CNC machine tools, industrial robots, medical equipment, and 3C automation production lines, ensuring smooth and noise free operation of the equipment, high repeat positioning accuracy, and assisting in the dual improvement of production efficiency and quality.
Product Highlights
Ball linear guide slider, as the core transmission component of modern industry, its product highlights revolve around core performance such as high precision, high load, low friction, long life, and intelligence
High precision positioning
Theball bearing carriages and guide rails adopts a four column ball circulation design, with adjustable preloading levels (light/medium/heavy) and a friction coefficient as low as 0.001, achieving micrometer level repetitive positioning accuracy and meeting the requirements of precision machining and testing
Super load capacity
The guide rail has undergone deep hardening treatment (HRC58-62), with a dynamic load of 15kN and a static load exceeding 30kN, suitable for high-strength scenarios such as heavy-duty stamping equipment and automated logistics lines.
Modular and flexible adaptation
The slider supports both flange and square installation structures, and the guide rail can be freely spliced to a length of 30 meters, compatible with complex mechanical layouts and increasing installation efficiency by 40%.
Long term protective performance
The slider comes standard with multi-layer sealed end caps and dust-proof scrapers (IP54 level protection), and the guide rail surface is plated with hard chrome or blackened to effectively resist dust, oil, and humid environments, extending its lifespan by more than three times.

frequently asked questions
What key steps should be noted when installing a Ball Linear Guide Slider?
Installation must follow the principle of "Datum Fitting → Lateral Fixing → Symmetrical Fastening": First, clean the guide rail and mounting surface to remove anti-rust oil, burrs, and contaminants; fit the datum surface of the guide rail tightly against the machine tool assembly surface, and lightly pre-fix it with bolts; use a side jacking device to make the datum surface of the guide rail fully fit the side of the machine bed; finally, use a torque wrench to tighten the bolts in a crisscross sequence from the middle to both ends to avoid deformation caused by one-sided force. Note: Bolt torque standards vary by brand, so refer to the product manual. Do not forcefully tighten misaligned bolts, otherwise the precision and service life will be directly affected.
How to judge whether the guide rail installation is qualified?
After installation, the following inspections are required: The slider moves without jamming and with uniform resistance throughout the process; the parallelism error of the guide rail detected by a level gauge is ≤ 0.1mm/m; there is no abnormal noise when manually sliding the slider, and no obvious movement after stopping. If increased local resistance is found, it may be due to poor fitting of the datum surface or residual foreign matter, and re-dismantling and inspection are required.
What are the causes of slider jamming or precision degradation?
Common causes include: ① Insufficient lubrication leading to dry friction; ② Failure of protection devices allowing iron filings/dust to enter the guide rail; ③ Long-term heavy loads causing rail wear; ④ Thermal expansion and contraction resulting in changes to fitting clearance. First, check the sealing performance of the protective cover (the mesh width of the metal cover must be < 12.5mm), clean it, and then perform re-lubrication testing. If abnormalities persist, it is necessary to inspect the guide rail parallelism and the condition of the rolling elements.
How to extend the service life of guide rails?
In addition to standard lubrication and protection, the following must be avoided:① Impact loads exceeding 150% of the rated load;② High-speed start-stop under no preload condition;③ Flatness error of the mounting surface > 0.05mm/m.Regularly inspect the slider clearance every 100km of operation. When the clearance exceeds 0.02mm, the slider or guide rail must be replaced.
