Key Features

Designed for applications requiring a very small radial section height due to low cross-sectional height.
Suitable when the housing bore does not serve as a raceway for needle roller and cage assemblies.
Supports high radial loads as a pure radial bearing with sealed end type.
Requires a smaller radial design envelope compared to machined needle roller bearings.
Can run directly on the shaft without an inner ring and permits relatively high speeds.
Easy to mount without additional means of axial retention, simplifying housing bore production.
Can close off shaft ends of bearing positions with drawn cup design and sealed ends.
Compact, cost-effective, and economical solution for compact bearing arrangements.

Product Description

INA HK4520-2RS-A-L271 is a high-performance roller bearing drawn cup needle designed with a 45 mm inside diameter and 52 mm outside diameter, sealed for enhanced durability and protection.

This bearing type is ideal for industrial machinery requiring a bearing with a very low radial section height, allowing applications in tight spaces. It is used when the housing bore is unsuitable as a raceway for needle roller and cage assemblies, providing a reliable solution for high radial loads.

Due to its design, it has a significantly smaller radial envelope than traditional machined bearings, improving compactness and efficiency in mechanical assemblies. The bearing typically runs directly on the shaft without an inner ring and permits relatively high rotational speeds, making it suitable for demanding mechanical environments.

Mounting is straightforward, as the bearing requires no additional axial retention means, facilitating easy installation and reducing manufacturing complexity of the housing bore. The drawn cup, sealed end design allows it to close off shaft ends effectively while protecting internal components from contamination, ensuring extended service life.

Designed for very low radial section height applications. Suitable for housings where bore is not used as raceway. Supports high static and dynamic radial loads. Smaller radial envelope than machined Roller Bearings. Runs directly on shaft without inner ring.

Permits relatively high speeds. Easy installation without axial retention aids. Sealed ends provide contamination protection. Compact and economical bearing solution.

This bearing is widely used in industrial, mechanical machinery, manufacturing, and automation applications where reliable, compact, and high-load radial support is essential. Its design advantages contribute to cost-effective solutions without compromising performance.
