Metric Series 80.000 Millimeter (mm) Width (B), 620,000 Newton (N) Dynamic Load Rating (Cr), and 1,770,000 Newton (N) Static Load Rating (Cor) Precision Needle Roller Bearing

Needle roller bearings are essentially cylindrical roller bearings except that their cylindrical rollers have a length 3 to 10 times their diameter (versus less a length less than 3 times their diameter). Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity.

Even though they have a low cross section, precision needle roller bearings have a high radial load capacity and are exceptionally suited for bearing applications where radial space is limited.
