SKF Lock Nut 21x25x5mm For Use With Bearing, KM 2

Want to keep a bearing locked in place on a shaft? Trust this lock nut-type assembly from SKF to hold it securely in position. It prevents slippage or loosening when machinery moves and vibrates, so wear is minimised and productivity stays on course. Thanks to the unit's standard metric thread, it's a cinch to take on and off. If you need to loose or tighten the nut, an HN 2-3 hook spanner (such as 204-4538) gets a reliable grip on the pre-machined grooves.

• M15x1 thread makes it compatible with standard parts
• Width of 5mm is well-suited to installations with limited space
• Light weight of just 11g puts minimal strain on your system

• Industrial assembly and packaging lines
• Medical imaging equipment
• Automotive industry
• Railway applications

Yes – as long as it's undamaged after disassembly, you can reuse this lock nut. To ensure a secure fit, it's important to replace the lock washer (237-2230) when reinstalling it.

Thanks to an axial static load-carrying capacity of 14.6kN, this lock nut has the muscle to support heavy-duty bearing assemblies.
