• Turning type needle bearings are bearings with small section height and large load rating.
• The outer ring has stable rigidity and can be easily used with light alloy housings.
• There are two types: without inner ring and with inner ring. In the case of without inner ring, compact design is possible if the shaft is used as a raceway.
• This bearing combines a brimmed outer ring with a unique lightweight and rigid cage and needle roller.
• During rotation, the cage accurately guides the needle roller to obtain the optimum load distribution.
• NA49 of the metric series is a bearing that conforms to the ISO standard.
