The NTN HK series needle roller bearing is a radial bearing with a machined outer ring and a steel cage. It handles high radial loads in applications where radial space is limited. Typical uses include transmissions, pumps, compressors and agricultural machinery. MR Industrial Accessories supplies this series to customers across the United States and Latin America.
Reading the HK code helps you identify a bearing quickly. The letters HK indicate a needle roller bearing with a machined outer ring and steel cage. The following digits give the main dimensions: the first two for bore diameter and the next two for width. For instance, HK3512CV2 has a 35 mm bore and a 12 mm width. The CV2 suffix points to a steel cage and lifetime lubrication.
These bearings are common in transmission cases, hydraulic pumps, air compressors, machine tools, mining equipment and agricultural machinery. Their compact design and high radial load capacity suit applications where radial space is tight and speeds are moderate. They also appear in conveyor rollers, pulleys and lifting systems, where reliability matters.
When selecting an HK bearing, review the radial load, rotation speed and environmental conditions. Sealing is critical: in dusty or damp settings, choose variants with integrated seals or add proper external sealing. Use the lubricant specified by the manufacturer, typically a high-quality bearing grease. During mounting, ensure precise alignment between shaft and housing and a correct fit to avoid undue axial loads and extend service life.
NTN HK series bearings are interchangeable with those from other recognized brands when the bore diameter, outer diameter, width and cage type match. For a quote, provide the complete code so we can confirm the exact equivalent. Our team can also suggest a compatible alternative for your equipment.

Frequently asked questions
- What does the CV2 suffix mean in an HK bearing?
- The CV2 suffix indicates a variant with a steel cage and lifetime lubrication. This configuration is common where reduced maintenance is desired. Contact our technical team to confirm this variant for your application.
- How do I choose between an HK bearing and a ball bearing?
- HK bearings support higher radial loads in reduced spaces, while ball bearings are more suitable for combined loads and high speeds. The choice depends on load, speed and available space. We can advise based on your application.
- What dimensions should I take into account to replace an HK bearing?
- Check the bore diameter, outer diameter and width. These appear in the code; for example, HK3512CV2 has a 35 mm bore and a 12 mm width. If unsure, send us the dimensions and we will quote the exact reference.
