SF-PK
Properties
The SF-PK bearing is an advanced bearing. The benefit of this type of bushing lies in its improved properties when used in water or with small quantities of oil.
The PEEK layer is over 0.1 mm thick, meaning that this type of bushing has a longer service life than the SF-1X. These bushings are popular in high-quality shock absorbers as well as in rotary and lifting parts in military applications.
