Since the manufacturers of bearings, such as SNR, KOYO, FAG etc. assign different suffixes to the roller bearings for their characteristics, we have summarized the features in a comparison table of bearings for your better orientation. Fitting, therefore, is often determined based on previous experience and records. Standard fittings for needle bearings are shown in Tables 5.2 and 5.3. Generally, when mounting a bearing in a thin- wall housing or on a hollow shaft, tighter fitting is required. A split housing cannot be used with drawn cup needle bearings.
