NKS 37 LDI Needle Roller Bearing 37x52x22

NKS 37 LDI Needle Roller Bearing Without Inner Ring 37x52x22

NKS 37 LDI is a professional needle roller bearing without inner ring designed for applications requiring high radial load capacity with limited installation space. The needle roller construction with slender cylindrical rollers allows the bearing to support heavy radial loads while maintaining compact dimensions of 37x52x22 mm. NKS series bearings are widely used in gearboxes, pumps, compressors and industrial drive systems.

The design without an inner ring allows direct use of a hardened and precision machined shaft surface as the bearing raceway. This solution increases shaft rigidity, allows larger shaft diameter and reduces the overall dimensions of the bearing assembly.

Needle roller bearings use cylindrical rollers with a large length-to-diameter ratio, providing significantly higher radial load capacity compared with standard deep groove ball bearings of similar external dimensions. The machined outer ring construction improves structural rigidity and stable operation under dynamic loading conditions.

The NKS 37 LDI bearing is commonly used in:

• industrial gearboxes
• hydraulic pumps
• compressors
• production machinery
• agricultural equipment
• industrial drive systems
• conveyor equipment
• applications requiring high radial load capacity

The phrase NKS 37 37x52x22 needle roller bearing without inner ring is frequently searched in industrial maintenance environments and compact bearing assembly applications.
