A lock nut from the SKF HN series keeps a bearing firmly seated on its shaft and allows controlled axial adjustment during mounting and dismounting. It belongs to the mounting hardware used in rotating equipment and power transmission assemblies, where the bearing has to stay in place under combined axial and radial loads.
Reading the code helps you match the nut to the shaft. The letters HN denote the lock nut type, and the figure that follows refers to the shaft or thread diameter it fits. A code such as HN 4-16/SET spans nut sizes HN 4 through HN 16, while the /SET suffix means the item comes as a set. Check the entire designation before ordering so the thread and the bearing agree.
Typical users are plants in food processing, metallurgy, mining and petrochemicals, and the nuts show up on pumps, fans, conveyor belts, mills and machine tools. Maintenance and repair work is another common use, since the nut lets a technician tighten or release a bearing in a controlled way.
Selection starts with the shaft diameter and the thread form, both of which must correspond to the bearing being secured. Before mounting, clean the threads and apply the torque called for by the manufacturer; over-tightening can distort parts and under-tightening can let the nut back off. Where the assembly calls for a lock washer, fit it, confirm the bearing is aligned, then tighten. A lightly lubricated thread eases mounting and limits wear.
Nuts that follow the same dimensions and thread specification can stand in for one another across brands. Tolerances and material still deserve a check to confirm the substitute behaves the same way. Our team can review compatibility with the rest of your assembly.

- It shows the product is supplied as a set, normally with the nut plus the fastening elements such as washers or screws. Review the set contents against your mounting needs.
- How do I pick the right lock nut for a bearing?
- Confirm the shaft diameter and the bearing thread type. Measurements and thread pitch have to line up. If anything is unclear, send us the bearing code and we will advise.
- Can SKF HN nuts be swapped with other brands?
- Yes, when dimensions and thread type match. Check tolerances and material first. We can guide you on compatibility.
