Needle Roller Bearings

Specifications

Combined Needle Roller Bearings

These bearings integrate a radial needle roller bearing with a thrust bearing component, allowing them to accommodate both radial and axial loads simultaneously. They are ideal for applications with limited space and complex load demands, such as in machine tool spindles and construction equipment.
