Track Roller Bearing (LFR5204-16-2Z, LFR5204-16-2RS)
| ● LFR Series Roller Bearing linear rail guide wheel in the most widely used, economical and practical products that can fit in the cylindrical guide, running a smooth, error, run a very low noise, high speed operation. ● wheel contact with the guide for the two 60-degree contacts of contacts with good performance and operation of the resistance is very small, so as to achieve a longer life. ● wheel double row angular contact ball bearings of the internal structure of the design and thickening of the outer ring, so that the wheel has a higher carrying capacity, wheel bearings eccentric and concentric configuration after loading a simple axis. ● roller bearings with high-quality steel or stainless steel, after heat treatment, precision grinding together, and fill in the internal long-life high-quality multi-purpose grease. Shielded metal wheel dust (KDD) or rubber seals (NPP). |
