INA Drawn Cup Needle Roller Bearing 4 mm Inside Diameter 8 mm Outside Diameter HK0408-B

INA HK0408-B drawn cup needle Roller Bearing features a 4 mm inside diameter and 8 mm outside diameter, engineered for efficient load support in demanding mechanical environments. This single-row bearing utilizes high-quality steel and a sheet steel cage to deliver robust performance and sustained longevity.

With a static load rating of 1310 N, the bearing withstands significant pressure without deformation, ensuring reliability in heavy-load applications. The dynamic load rating of 1780 N complements this by providing durable support during variable operational loads. It also achieves a limiting speed of up to 42500 rpm, making it suitable for high-speed applications in manufacturing and automation.

The bearing's open end design allows for convenient maintenance and inspection, reducing downtime. The parallel bore type ensures precise installation and operation consistency. The cage made of sheet steel offers an optimal balance of weight and strength, improving overall bearing efficiency. This bearing supports grease lubrication speeds up to 25500 rpm and oil lubrication speeds up to 42500 rpm.

Commonly employed in automation machinery, electrical devices, and precision mechanical systems, the INA HK0408-B bearing is essential for applications requiring compact form factor but high performance. Its drawn cup needle configuration makes it well-suited for tight spaces where load capacity and compactness are critical.
