SKL high-precision cylindrical roller bearings usually consist of outer rings, inner rings with tapered bores, cylindrical rollers and cages. The outer rings of the vast majority of models adopt a separable design. Classified by the number of rolling element rows, they are divided into single-row ultra-precision cylindrical roller bearings and double-row ultra-precision cylindrical roller bearings. This series of bearings is suitable for working conditions with extremely high precision requirements and high radial loads, and is most commonly used in machine tool applications.
