⚙️Product description:
Type and Structure: SBR20LUU is a linear bearing slider. "SBR" represents the linear sliding unit series, "20" indicates its inner diameter is 20mm, "L" stands for the extended type, and "UU" means it has seals at both ends. It is composed of an open aluminum casing and a linear bearing. The aluminum casing has the characteristics of high hardness and light weight.
Bearing Materials and Properties: The outer ring and balls of the linear bearing are made of bearing steel Gcr15, which has high hardness and wear resistance, ensuring the service life and motion accuracy of the slider.
⚙️Product Advantages:
High precision: The positioning accuracy is high, capable of meeting various requirements for precise linear motion.
Low friction: The internal structure adopts a rolling bearing design, with a low friction coefficient, ensuring smooth movement and significantly reducing the power required for driving. At the same time, it reduces wear and maintains accuracy for a long time.
Low noise: During movement, the noise is relatively low, making it suitable for equipment with noise requirements for the working environment.
Strong load-bearing capacity: It can withstand loads from above and other directions, featuring high rigidity and stability.

| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
