SKF’s spindle nut locking system

SKF Forged Spindle Nut Locking SystemSKF’s spindle nut locking system for both tractors and trailers is available in steering, drive and trailer sizes and is forged, precision-machined and assembled with two high-strength lock bolts to help withstand adverse conditions. The two-piece system includes a hardened internal tab lock washer and a forged precision-machined flange nut – a combination that meshes with precision-formed threads to help facilitate added strength.

The system is designed for easy installation and service and is engineered to provide consistent wheel bearing adjustment accuracy to help avoid the extremes of preload and excessive bearing end play.
