SF-1D
Properties
The SF-1D bearing is particularly suitable for linear or axial movements. This type of bushing is particularly wear-resistant and can retain lubricant well, even if it has a long service life. It also simultaneously protects the mating surfaces from wear and tear.
This type of bushing is generally used as a piston ring in shock absorbers for cars and motor cycles and for various hydraulic cylinders, hydraulic motors and pneumatic components.
