Spherical washers from SKF are designed to create an exact, parallel plane between the bolt head and the face of the nut. These washers automatically adjust and compensate for the angular deviation between the planes and prevent the bolt from bending.

Another major advantage of the spherical washer is that it has been engineered to enable to easily machine down its height. Standard SKF spherical washers come in surface treated alloy steel. SKF stocks the standard height (type SW), and low profile (type SWLP) version. The treated surface gives the SKF spherical washers protection in humid and salty environments.
