LR15 LR20 LR25 Track Roller Bearings Deep Groove Ball Structure for Precision Guide Systems
LR15, LR20, and LR25 are high-precision track roller bearings integrated with a customized groove design and deep groove ball internal structure, tailored for diverse guide and transmission scenarios in light-to-medium load industrial equipment. The specialized groove structure enables flexible matching with various industry-standard guide rails, while the deep groove ball core structure enhances radial load capacity and ensures low-friction, low-vibration rolling performance. Crafted from premium GCr15 bearing steel, these bearings undergo precision heat treatment and groove superfinishing, delivering excellent wear resistance, corrosion resistance (with optional surface coating), and stable operation during long-duration continuous work. They support customized groove dimensions, inner/outer diameters, and sealing structures to meet personalized equipment requirements, making them a core component for precision guide systems in small-to-medium industrial devices.

FAQ
-
Q: What guide rail types can LR-series bearings match with?
A: They can be matched with various industry-standard guide rails through customized groove dimensions, adapting to different guide scenarios of small-to-medium industrial equipment.
-
Q: Does the deep groove ball structure affect the bearing’s load capacity?
A: No, the deep groove ball structure enhances radial load capacity and reduces rolling friction, ensuring stable load-bearing and smooth operation in light-to-medium load working conditions.
-
Q: Can LR-series bearings be customized with anti-corrosion features?
A: Yes, optional anti-corrosion surface coatings (such as zinc plating or passivation) can be added to adapt to humid or corrosive working environments.
