What is a lock nut (AN nut)
The nut is one of the locking elements used to assemble mechanism parts. It can withstand vibration and ensure complete resistance even when it is not locked.
An opening called an internal thread is machined in the center and used in combination with externally threaded (externally threaded) parts such as bolts. The nut used to fix the bearing is called a lock nut, which can be locked and removed for repeated use.
Like the sun nut, it is manufactured in accordance with the JIS standard "JIS B 1552". Mainly used with bearing washers (sun washers).
