INA Needle Roller Bearing NKIS25-XL, 25 mm ID, 47 mm OD, 22 mm Width, Parallel Bore, Steel Cage

The INA NKIS25-XL needle roller bearing is a specialized roller bearing featuring a 25 mm inside diameter, a 47 mm outside diameter, and a 22 mm race width. This bearing is designed for demanding mechanical and industrial environments where high load capacity and precision are essential. It incorporates a parallel bore type and a robust steel cage, both contributing to the reliable operation and mechanical strength of the assembly.

This bearing is constructed as an open end type, making it adaptable to various housing configurations and allowing for straightforward lubrication, whether oil or grease. It is engineered to handle a static load rating up to 43.5 kN and a dynamic load rating of 38 kN, supporting both radial and axial load conditions in compact and high-output machinery.

The bearing design leverages X-life technology, with optimized raceway surfaces for enhanced load distribution and extended operating life. The high precision of the inner and outer rings ensures smooth rotation and leads to better vibration control, which is critical for advanced industrial, construction, and automation systems.

INA's NKIS25-XL roller bearing can reach rotational speeds up to 14000 rpm, depending on lubrication, and its steel cage offers resistance to distortion under heavy loads. The bearing can be used in applications such as gearboxes, pumps, compressors, electric motors, and other rotary assemblies requiring efficient power transmission and minimal friction losses.

Its compact 22 mm width enables installation in limited space environments, ensuring versatility across mechanical engineering, manufacturing lines, agricultural equipment, and HVAC drives where reliability under continuous operation is paramount. The open end facilitates routine maintenance and onsite inspection under industrial standards.
