Rolling bearings; Locknuts, narrow series, and lockwashers with straight inner tab

This technical specification establishes the dimensional requirements and geometric tolerances for lock nuts and lock washers featuring straight locking tabs, specifically designed for use with narrow series rolling bearings. The document outlines precise measurements for thread engagement, overall thickness, and radial clearance to ensure reliable mechanical performance in rotating machinery applications. It defines the interface parameters necessary for compatibility between these fastening components and bearing assemblies, facilitating interchangeability across different manufacturing systems. The scope covers the structural integrity and form factors required for these locking devices under standard operating conditions, focusing on the prevention of axial displacement through the use of integrated locking tabs. By providing a unified set of criteria for these elements, the specification supports consistent engineering practices in the design and maintenance of mechanical systems where secure fastening is critical. The guidelines address both the nominal dimensions and the allowable deviations to guarantee functional reliability in diverse industrial contexts where narrow series bearings are utilized.
