    Product Description

    NA4904 Machined Needle Roller Bearing

    Key Features 

    NA4904 Machined Metric Type Needle Roller Bearings has both an Inner Ring and an outer ring capable of handling large load ratings and is manufactured with a low sectional height. The outer ring has high rigidity and can even be easily used as a light housing. This NA4904 Machined Needle Roller is made from Chrome Steel, its outer ring has high rigidity and can be used with or without an inner ring. Our Machined Type Needle Bearings are available in both metric and inch sizes and are suitable for a wide range of applications involving heavy loads with either high-speed or low-speed rotation. This type of bearing, without an inner ring, uses a shaft as the raceway surface making its design more compact. Our Roller Bearings are pre-lubricated with light oil to allow them to be ready to use upon arrival.  

    Applications / Industries

    NA4904 Machined Type Needle Roller Bearings are used for Textile Machines, Printing Machines, Copy Machines, Washing Machines, Paper Towel Dispensers, Fitness Machines, Conveyor Systems, among others.
