    NA4908-RS Needle roller bearings with machined rings, with an inner ring

    Short Description:

    The Needle Roller Bearings are bearings with machined rings made of bearing steel that have a low sectional height and a high load carrying capacity. The outer ring has stable, high rigidity and can be used even for light alloy housings. The Machined Needle Roller is made from Chrome Steel and can be used with or without an inner ring. This type with an inner ring uses a shaft as the raceway surface, making its design more compact.
