Key Features

This bearing supports high radial loads due to its pure radial bearing design.
The compact drawn cup design allows for a very low cross-sectional height.
Its sealed construction ensures protection against contaminants and long service life.
Typically runs directly on the shaft without an inner ring, reducing assembly complexity.
The bearing permits relatively high speeds, suitable for demanding mechanical applications.
Requires no additional means of axial retention, easing mounting processes.
Offers a considerably smaller radial design envelope compared to machined needle roller bearings.
It is suitable for applications where housing bores are not suitable as raceways for needle roller cage assemblies.

Product Description

INA HK4518-RS-A-L271 Drawn Cup Needle Roller Bearing features a 45 mm inside diameter and 52 mm outside diameter, with an 18 mm race width. It uses a steel cage and is sealed for protection, which makes it highly suitable for industrial, manufacturing, and mechanical applications requiring compact radial bearings with high load capacities.

Drawn cup needle roller bearings are specialized for applications requiring very low cross-sectional heights while supporting high radial loads. This bearing design runs directly on the shaft without needing an inner ring, simplifying installation and ensuring robustness.

The sealed end type protects the bearing from dirt and debris, increasing longevity and reducing maintenance requirements. Its compact design results in a smaller radial envelope compared to traditional machined needle roller bearings, making it ideal for tight spaces.

This bearing is commonly used in automotive assemblies, industrial machinery, conveyor systems, and other mechanical equipment requiring reliable, high-speed radial bearing performance.

Supports high radial loads with a pure radial bearing design. Very low cross-sectional height for compact installations. Sealed construction provides effective protection. Runs directly on the shaft without an inner ring.

Permits relatively high operating speeds. No additional axial retention needed, simplifying mounting. Offers cost-effective and economical bearing arrangements. Suitable when housing bores cannot act as raceways. Steel cage material ensures durability.

For reliable performance and ease of installation in compact spaces, INA drawn cup needle roller bearings like the HK4518-RS-A-L271 are a trusted choice in industrial supply chains. Explore our comprehensive range of Roller Bearings for various industrial and mechanical needs at EnvMart.
