Stop bearings from working loose with this nifty locknut from SKF. Its precise cylindrical shape means it's easy to fit over a shaft. An internal M85x2 thread means you can simply screw it onto a compatible adapter sleeve or shaft. With no machining necessary, it's a quick fix. Four slots around the outer edge enable your hook spanner to grip the nut, so you can tightly secure it. When it's used with a washer (237-2229), the locknut won't loosen under machine vibrations, making it an essential bit of kit for building and maintaining your automation and motor applications.
