Machined Type Needle Roller 2RS with Inner Ring (NA49)

• Metric series.
• Type, dimension 49 (NA49).
• Cage needle roller bearing with inner ring two side seals (2RS).

About Machined Type Needle Roller Bearings

• Machined Type Needle Roller Bearings have an outer ring made by machining, heat treatment, and grinding.
• The outer ring has stable high rigidity and can be easily used even for light alloy housings.
• These bearings are available in various types and optimally selectable for different conditions such as heavy loads, high-speed rotation and low-speed rotation.
• They are most suitable for general-purpose applications.

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.
