Lock nuts in the SKF HNA series hold bearings and related components firmly in place on a shaft. Their threaded design simplifies both installation and removal, which helps when equipment needs to be serviced or rebuilt. MR Industrial Accessories LLC supplies this line as part of a broader range of power transmission and mounting products.
The code itself tells you what you are looking at. HNA identifies the series, and the numbers that follow point to a shaft diameter range. A smaller designation such as HNA 1-4 serves smaller shafts, while HNA 14-24 is intended for larger ones. Any suffix would signal a different design or material variant.
These lock nuts appear in food processing, metallurgy, petrochemical and mining operations, among others. They are common on gearboxes, pumps, fans and conveyors, where their job is to hold bearings in their axial position and stop movement that could lead to early failure. Machine tool spindles also use them when a precise, secure fit is required.
Selection starts with the shaft diameter and the bearing that will be secured. Check that the thread matches the shaft and that the nut can handle the load. Before mounting, clean the threads and apply a suitable lubricant to ease fitting and reduce the risk of seizing. Align the parts carefully, and tighten with the correct tool so the nut is not damaged.
Interchangeability is possible with lock nuts from other manufacturers when thread and dimensions match, but compatibility should always be confirmed first. Our team can review your application and suggest equivalent options.

Frequently asked questions
- How do I select the correct HNA nut for my shaft?
- Start with the shaft diameter and the bearing you need to secure. The HNA number indicates a diameter range, so HNA 1-4 is for smaller shafts. Confirm the thread matches and the load capacity is suitable. If you are unsure, contact us via WhatsApp.
- Can HNA nuts be used with bearings from other brands?
- Yes, as long as the thread and dimensions are compatible. Check the pitch and diameter against your bearing. We can help verify interchangeability before you order.
- What should I keep in mind when mounting a lock nut?
- Clean the threads and apply a suitable lubricant to prevent seizing. Use the correct tool and tighten to the manufacturer's specifications. Make sure the bearing is aligned and avoid over-tightening, which can damage the thread or the bearing.
