AW series
What are Bearing Washers/Star Washers (AW Washers)?
Used with locking nuts, one tooth on the inside and multiple teeth on the outside.
Fit the internal teeth into the grooves cut in the shaft and fold one of the external teeth into the groove on the outer circumference of the lock nut to prevent loosening.
Like the lock nut, it is manufactured in accordance with the JIS standard "JIS B 1552".
