Axle Outer Nut, Tapered
SAF-Holland

The tapered axle outer nut is a critical securing component for wheel-end assemblies, designed to maintain proper preload on bearings and ensure axial stability during high-load operation. The tapered geometry helps to achieve a precise, self-locking fit as the nut is tightened, reducing the risk of loosening under dynamic loads and road vibrations. Proper torque specification and thread condition are essential during installation to maximize service life and safety. Consistent use of matched torque values helps minimize uneven bearing wear and potential heat buildup. When replaced as part of routine maintenance, this nut supports reliable wheel performance and alignment across the fleet.
