The ZLV Car Ladder Optical Axis is an essential component in a multitude of industries, boasting impressive precision and durability. It excels in terms of its processing accuracy at ±0.002mm, ensuring a smooth and efficient operation. The surface roughness is a mere 1.8um, and its competitive unit price of 0.02 USD per meter makes it a valuable investment for any industrial machinery.


Crafted from top-grade 45# steel, the Car Ladder Optical Axis exhibits extraordinary hardness, measured at HRC62+2. The surface hardening thickness is maintained between 0.8mm and 2.5mm, while the roughness is kept at Ra0.2-0.4. The application of chromium measures between 0.015mm and 0.025mm, ensuring its superior corrosion resistance and durability. Finally, its straightness is precisely 80μm/1000mm, providing exceptional linearity for mechanical operations.


This versatile product finds extensive use in various industrial machinery and accompanying equipment. Industries such as packaging and printing machinery, woodworking machinery, fitness equipment, power tools, textile machinery, light industry machinery, and automated equipment rely heavily on the ZLV Car Ladder Optical Axis.


ZLV’s Optical Axis undergoes unique grinding and hard chromium plating techniques. It is then polished to a mirror finish, enhancing its wear and corrosion resistance. This robust component’s hardness significantly extends the lifespan of conventional precision mechanical instruments, making it an indispensable asset for any mechanical operation.
