Needle roller+thrust roller - NKXR

NKXR is a compact combination bearing of radial needle rollers and unidirectional thrust cylindrical rollers. The needle rollers bear heavy radial loads, while the thrust cylindrical rollers bear unidirectional large axial loads (with significantly higher axial load capacity than the NKX series of thrust ball combinations). The separable structure is easy to install and suitable for industrial scenarios with radial heavy loads, unidirectional large axial positioning, compact space, and impact resistance. It is widely used in automotive transmissions, motors, pump valves, compressors, precision machine tools, and other equipment
