INA 45 mm ID Drawn Cup Needle Roller Bearing Open End 52 mm OD HK4516-A-HLA

INA HK4516-A-HLA Drawn Cup Needle Roller Bearing features a 45 mm inside diameter and 52 mm outside diameter, with a 16 mm race width and open end design. This bearing type is particularly suitable for applications demanding minimal radial section height due to its low cross-sectional height.

Primarily used when the housing bore cannot serve as a raceway for needle roller assemblies, these bearings provide pure radial load support and allow for relatively high speeds. Its steel cage construction ensures durability and reliable performance under heavy radial loads.

The design permits mounting directly on the shaft without an inner ring and requires no additional means of axial retention, simplifying the manufacturing of the housing bore. It is also suitable for compact, cost-effective bearing arrangements in various industrial applications.

The bearing has a 45 mm bore diameter with parallel bore type ensuring precise fit. It has a 16 mm race width optimized for compact installation spaces. Constructed with a steel cage providing strong and durable assembly.

Static load rating of 43 kN and dynamic load rating of 21.3 kN for heavy-duty radial loads. Open end design facilitating easy mounting and shaft end closure capabilities.

Drawn cup needle bearings like the HK4516-A-HLA are extensively used in industrial, mechanical machinery, automotive, and manufacturing equipment where space optimization, high load capacity, and economical bearing solutions are critical.
