Double row cylindrical roller bearings

Series nN30 and nNu49 double row cylindrical ro ller bearings are separable radial bearings. Their main dimensions are standardized by dIN 5412/part4. They are used as non-locating bearings in bearing arrangements of machine tool spindles. therefo re, these bearings are normally used in high pre- cision tolerance class, frequently in combination with reduced internal clearance. These bearings also feature high radial load ca pacity and are satisfactory for high speed appli cations, providing a very stiff and rigid bearing arrangement. They are also commonly used with tapered bores, namely suffix K(i. e taper 1: 12).
