The so-called bearing type value (kf) assumes the actual design of the bearing to be lubricated. This factor can have values between 0.9 and 10 for kinematically simple ball bearings. For kinematically complex bearings (like axial cylindrical roller bearings with high sliding friction) the kf factor can reach values up to 90.

SKF Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials. The bearings can meet the challenges of applications faced with heavy radial loads and high speeds.
Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
