IKO RNA4903 Needle Roller Bearing w/o Inner Ring 22x30x13mm

About Structure and Features

• Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings.
• The outer ring has high rigidity and can easily be used even for light alloy housings.
• These bearings are available in metric series and inch series, both of which have the caged type and the full complement type.
• It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations.
• In addition, there are bearings with and without an inner ring.
• As the type without inner ring uses a shaft as the raceway surface, a compact design is possible

Machined Type Needle Roller Bearings (NA49UU, NA69UU, TAFI, NK, NKS inner ring types, with and without inner ring) provide high radial load capacity in compact axial space for gearboxes, pumps, and precision machinery.
