Product Description
INA HK2520-B is a high-quality drawn cup needle roller bearing with a 25 mm inside diameter and 32 mm outside diameter, meeting the needs of applications requiring compact radial support within limited space. It features a parallel bore and an open end for direct lubrication access, making maintenance efficient.
This single-row bearing uses a sheet steel cage to maintain precise roller spacing, resulting in smooth rotational performance even under load. Its dynamic load capacity of 19900N allows it to withstand continuous operational forces, while the static load rating of 33000N provides excellent resistance against heavy standstill loads without permanent deformation.
The HK2520-B supports speeds up to 6100 rpm when grease-lubricated and up to 10200 rpm when lubricated with oil, catering to different operational requirements. Its drawn cup construction provides a minimal radial envelope, suitable for applications with tight radial clearances.
Common industrial applications include automotive transmission shafts, industrial gearboxes, and linkage assemblies requiring needle roller support. It works well in rotating cam applications with limited diameters and conveyor drive rollers demanding high static resistance.
The bearing's open end design enables straightforward maintenance through direct lubrication and visual roller inspection. Its parallel bore design ensures compatibility with cylindrical shafts lacking taper.
