Inch Series 1.0000 Inch (in) Width (B), 4,500 Pound (lb) Dynamic Load Rating (Cr), and 6,400 Pound (lb) Static Load Rating (Cor) 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 a length less than 3 times their diameter). Needle bearings are also essentially bearings that utilize small & cylindric rollers. 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, needle roller bearings have a high radial load capacity and are exceptionally apt for bearing applications where radial space is limited.
