SL Bearing is a kind of full complement cylindrical roll bearings. WD double row full complement cylindrical roller bearings (SL 0450XX-PP Series) is particularly used in rope pulleys. These bearings have the following features.
1. High radial load carrying capacity and rigidity, due to full complement cylindrical roller design.
2. Accommodation of axial load and tilting moments.
3. Suitable for low to medium speed applications.
4. Special material and heat treatment to extend the bearing lifetime up by 60%
5. Special material of sealing rings to improve the sealing quality as well as wear. oil and low temperature resistance.
6. Suitable for low or high temperature and heavy load conditions due to special grease. Lubrication holes in outer and inner rings enable easy re-lubrication
When WD SL bearing is mounted on the rope pulleys, there’s no additional sleeves or distance pieces required, due to the narrower outer ring of SL bearing. And the two snap ring on the outer ring of SL bearing enable simple bearing arrangement design for pulleys.
