Core Advantages
1. Durable and resilient, easily handles complex working conditions:
Selected high-adaptability bearing steel is paired with a mature heat treatment process to enhance product hardness and wear resistance from the source. Even after long-term operation under high-frequency reciprocating motion or heavy-load conditions, it can effectively reduce component wear, extend the overall service life of the equipment, and save considerable maintenance costs for enterprises. The surface protective coating serves a dual purpose, resisting harsh environments such as moisture and corrosion while ensuring smoother operation, making sure the equipment runs reliably under various conditions.
2. High-precision guidance, ensuring stable equipment performance:
Key indicators such as outer diameter, surface finish, and straightness are all calibrated to high industrial standards, maximizing compatibility with various linear bearings. In actual operation, it provides precise and stable motion paths for the linear and reciprocating movements of mechanical components, fundamentally preventing issues like positioning errors or operational stuttering caused by guidance deviations. This allows high-precision equipment such as automated production lines and precision machine tools to consistently operate efficiently.
3. Flexible customization, perfectly suited for non-standard assembly requirements:
Supports diverse shaft-end processing and can be flexibly adjusted according to the assembly requirements of different equipment, easily integrating with various non-standard mechanical designs. There is no need to modify the equipment structure to fit standard parts, shortening development and assembly cycles while improving the overall cost-effectiveness of the solution, giving equipment manufacturers more flexibility in selection.
4. Application scope:
Thanks to its stable guidance performance and excellent durability, the SFC linear shaft is widely used in core equipment across the industrial automation sector. Whether it's precise joint transmission in industrial robots, slide table feeding in precision machine tools, reciprocating positioning in automated cutting equipment, smooth operation in medical instruments, material transport on electronics production lines, or extension control of pneumatic push rods, it plays a key role. It also meets the customization needs of various non-standard automation machinery, providing reliable support for linear motion systems under different working conditions.

FAQ
1. Q: Does the linear optical axis need maintenance? What is the focus of daily maintenance?
Answer: Maintenance is required, and the core maintenance focuses on rust prevention and cleaning:
If the carbon steel optical shaft is idle for a long time, it is necessary to apply anti-rust oil and wrap it with protective film to prevent surface rust;
During operation, regularly clean up dust, iron filings and other impurities on the surface to avoid impurities entering the inside of linear bearings and causing wear;
When used with linear bearings, lubricant should be added to the bearing simultaneously to indirectly reduce the friction loss between the optical shaft and the bearing.
2. Q: How to deal with rust or scratches on the surface of the linear optical axis?
Answer: Targeted treatment according to the degree of damage:
Slight rust: Sand the rust area with fine sandpaper, apply anti-rust oil or re-chrome after cleaning;
Slight scratches: If it does not affect the accuracy of movement, it can continue to be used after polishing;
Severe rust or deep scratches: It will cause linear bearings to stuck and wear will increase, so it is recommended to replace the optical shaft directly to avoid damaging the bearing components.
3. Q: What factors affect the service life of linear optical shafts?
Answer: There are three core influencing factors:
Surface treatment process: chrome plating and grinding treatment of optical shaft has stronger wear resistance and longer life; The unprotected optical shaft is prone to rust, and the service life is greatly shortened;
Load and working conditions: Overload and offset load will accelerate the surface wear of the optical shaft, and dusty and humid environment will aggravate rust;
Fit accuracy: Too large or too small a mating gap with linear bearings will increase friction and shorten the service life of the optical shaft and bearing.
4. Q: In the scene of ultra-long stroke, can the linear optical axis be spliced?
Answer: Yes, but you need to do a good job of splicing accuracy control:
The splicing part should be processed into a concave and convex tenon structure to ensure coaxiality and avoid steps;
After splicing, use a laser straightness to calibrate the straightness, and the error should be controlled within 0.01mm/m;
Dust-proof seals should be installed at the splicing to prevent impurities from entering the gap and affecting the operation of linear bearings.
