NH Series Bearing Locknuts – Inch, Heavy Duty
The NH series is the heavy-duty inch bearing locknut: a thicker, higher-strength body for bearing seats carrying high axial thrust, matched with the correspondingly heavy WH series lockwasher. Where a standard N nut and W washer are at their limit, the NH/WH pair carries the load without deforming the spanner slots or fatiguing the washer tab.
