INA Needle Roller Bearing 40 mm Inside Diameter 65 mm Outside Diameter NKIS40

INA NKIS40 is a high-performance needle roller bearing with a 40 mm inside diameter, 65 mm outside diameter, and 22 mm race width, made with a steel cage and open end type design.

These needle roller bearings are X-life series, featuring optimized raceway surfaces that deliver higher load carrying capacity and extended service life compared to standard bearings.

The bearing supports a static load rating of 67 kN and a dynamic load rating of 48 kN, making it suitable for heavy-duty industrial machinery. It is designed for applications requiring a maximum speed of up to 9500 rpm with oil or grease lubrication and features a parallel bore type.

Needle roller bearings with ribs are single or double row units consisting of machined outer rings with ribs, needle roller and cage assemblies, and removable inner rings, providing robust construction and service flexibility.

This bearing is ideal for industrial machinery, manufacturing equipment, and mechanical spares where durability and precision are critical. The steel cage construction ensures optimal durability under high load and speed conditions.

Open end design facilitates easier installation and maintenance in various mechanical assemblies. Suitable for HVAC systems, construction machinery, and water treatment plants requiring high reliability and performance. Maximum speed ratings are specified for oil and grease lubrication to ensure optimal bearing life and operation.
