For axial bearing retention and fine clearance adjustment on shafts, the SKF HM lock nut is a standard choice. It works in combination with a lock washer. The precision thread and sturdy construction support dependable clamping in tough industrial settings.
The part number follows a pattern. HM denotes a metric-thread lock nut. The digits immediately after HM give the size. A suffix such as CL7C shows the precision class and thread type. Variants like /2 and /010 indicate different designs. Always confirm the full identifier before ordering.
Typical uses include fixing bearings on machine tool spindles, gearboxes, pumps, fans and power transmission assemblies. Industries such as metallurgy, food processing, mining and petrochemicals rely on these nuts where secure, adjustable mounting is needed. In high-speed or variable-load equipment, they allow accurate control of axial clearance.
Selection depends on shaft thread diameter and pitch, the required tolerance class, and the matching lock washer. During installation, check bearing alignment and apply the specified torque to prevent distortion. A light thread lubricant aids adjustment and reduces wear. Recheck tightening at intervals, particularly where vibration is present.
SKF HM lock nuts can be replaced by equivalent products from other manufacturers when thread dimensions and tolerance class align. For a substitute, compare the complete part number and technical data. MR Industrial Accessories LLC supplies this line and can help you find a suitable equivalent without sacrificing performance.
