Bearing locknut built to the N-11 and SFN-11 industry standard, threading onto a shaft to clamp a bearing's inner race in place and prevent it from shifting axially under load. The standardized size cross-fits Hyster, Yale, Toyota, Caterpillar, Mitsubishi, Clark, and Crown wherever this bearing size is specified. If it loosens from vibration, the bearing it secures can shift and develop play, showing as wheel or shaft wobble.
This bearing locknut follows the N-11 and SFN-11 industry standard, a widely used size that cross-fits across multiple forklift brands including Hyster, Yale, Toyota, Caterpillar, Mitsubishi, Clark, and Crown wherever this bearing size is specified. Being an industry-standard part rather than a brand-specific one, it is manufactured by a range of bearing suppliers under the same N-11 designation.
The locknut is machined from steel with a 2.157 inch inside diameter, 2.9688 inch outside diameter, and 0.51 inch thickness, and weighs 0.5 pounds. Its function is to thread onto a shaft and clamp a bearing's inner race in place, preventing the bearing from shifting axially under load during operation.
As a threaded fastener under constant vibration and load, a locknut can loosen over time if not torqued to specification, which allows the bearing it secures to shift and develop play. A loose locknut on a load-bearing shaft typically shows up as increased wheel or shaft wobble and accelerated bearing wear. Because the N-11 size is standardized across the industry, this locknut is a practical stocking item for shops servicing a mixed fleet of forklift brands.
