Product Description

SKF NK 28/30 needle roller bearing features a 28 mm inside diameter, 37 mm outside diameter, and 30 mm race width. This bearing offers low sectional height combined with a very high load carrying capacity for its size, making it ideal for various industrial sectors including manufacturing, machinery, and automotive engineering.

Constructed with carbon chrome steel rollers and a reinforced Polyamide 66 cage, it provides excellent durability and wear resistance. The needle roller is designed without an inner ring, allowing direct installation on hardened and ground shafts where displacement is limited to the width of the raceway.

This bearing type includes an open end allowing easier lubrication and maintenance, suitable for environments requiring frequent servicing. With a static load rating of 60 kN and a dynamic load rating of 31.9 kN, it supports significant radial and axial forces. It features a maximum speed limit of 16,000 rpm and can operate safely at 14,000 rpm with oil lubrication and 9,000 rpm with grease lubrication.

Typical applications include industrial machinery, automotive components, and precision instruments requiring high-speed and compact bearing solutions. Inside diameter of 28 mm ensures precise shaft compatibility. Race width of 30 mm offers stable load support.

Carbon chrome steel rollers provide high wear resistance. Reinforced Polyamide 66 cage enhances bearing stability. Open end facilitates easy lubrication and maintenance. Maximum limiting speed of 16,000 rpm appropriate for high-speed mechanical applications.

Static load rating 60 kN and dynamic load rating 31.9 kN for heavy-duty performance. Designed for shaft applications where displacement is limited. Manufactured in Germany meeting high-quality standards.

This SKF Needle Roller Bearing NK 28/30 is a crucial component for various industrial and mechanical uses, ensuring smooth rotation, reduced wear, and long service life.
