INA Drawn Cup Needle Roller Bearing 45 mm Inside Diameter 52 mm Outside Diameter Steel Cage Sealed HK4512-B

INA HK4512-B drawn cup needle roller bearing is a high-quality rotary bearing designed for mechanical applications where space is limited and high radial loads must be supported. It features an inside diameter of 45 mm and an outside diameter of 52 mm with a race width of 12 mm. The bearing has a steel cage and sealed ends, allowing for a robust design that requires no additional axial retention. This product is particularly suitable for applications demanding a very small radial section height due to its low cross-sectional height.

These drawn cup needle roller bearings operate directly on shafts, without the need for an inner ring, making them easy to mount and maintain. They enable relatively high speed operation and are commonly used in various industrial machinery, automotive assemblies, and manufacturing equipment. The housing bore can be produced more easily since it is not required to serve as a raceway, and the bearing can also be used to close off shaft ends when equipped with a closed end.

The bearing supports high radial loads, benefiting applications that require durability and precise radial load handling while minimizing the mechanical footprint. Its compact design promotes economical use of space and cost efficiency in complex bearing arrangements.

Common use cases include industrial machinery, construction equipment, automotive components, and general manufacturing where rotary roller bearings are essential for performance and reliability.

Suitable for very small radial section heights due to low cross-sectional height. Capable of high radial load support as a pure radial bearing. Steel cage construction for strength and extended service life. Sealed ends for protection and ease of installation.

Requires no additional axial retention mechanisms. Runs directly on the shaft without inner ring necessity. Compact and cost-effective bearing solution. Explore a wide variety of rotary Roller Bearings and mechanical components on EnvMart for reliable industrial and manufacturing solutions.
