Combined Type Needle Roller Bearing With 3-Point Contact (NATB)

• Needle Roller Bearings with Three-point contact ball bearing.
• These bearings can withstand heavy radial loads and bi-directional axial loads at the same time during highspeed rotation.
• Since the non-interchangeable inner rings are separated at the center of the ball raceway surface, they must be firmly tightened against the shaft in the axial direction.
• The axial clearance of this bearing is 0.1 - 0.3 mm, and like NATA59, the axial load should not exceed 25% of the radial load.

About Combined Type Needle Roller Bearings

• Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing.
• Caged needle roller bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings.
• They can be subjected to radial loads and axial loads simultaneously.

About Structure and Features

• They are compact and very economical, and can be subjected to radial loads and axial loads simultaneously.
• They are widely used for machine tools, textile machinery, and industrial machinery.
