Having trouble securing your bearing to a shaft? Bolt it down with this assembly from SKF. It's a lock nut with a threaded design that makes it easy to attach to your shaft. To seal the deal, you should use one of the lock washers in the MB or MBL series (such as 237-2232) to ensure it doesn't come loose. This nut is reusable, so it's a sustainable choice you can keep for multiple applications.

• M20x1 metric thread is standard, for versatile use
• Outer diameter of 32mm and inner diameter of 20mm for a precise fit with compatible shafts
• Axial static load carrying capacity of 24kN indicates it can withstand heavy loads in stationary applications

• Automotive engineering
• Wind turbines
• Agricultural equipment
• Water treatment facilities

You can fix this lock nut by using an HN 4 hook spanner to tighten it to a bearing on your machine shaft. For convenience, the nut has four pre-cut slots around its diameter that are designed to give your spanner purchase and make tightening easy.
