Drawn cup needle roller bearing - ø 3 - 139.7 mm (0.1181 - 5.5")
Drawn cup needle roller bearings, are known for supporting relatively large radial loads and are capable of reducing friction between rotating components. They have a drawn outer shell, acting as a raceway for the rollers. Bearings are available in 3mm to 139.7mm bore size. Though the bearings feature a small cross section, they are capable of high-load capability in minimum space. With the help of a press fit housing, it is easy to install these cup bearings. As the outer ring can be drawn accurately, there is no need for subsequent matching. The bearings are available either in open ends or single, closed-end designs. Depending on applications these have two or integral seals. A single lubricating hole and matching inner ring are other options. The bearings are used in a variety of applications including transmissions, transfer cases, engines and valve trains, steering and braking systems, axle support and outboard engines.
