DISC BRAKE – MODEL SKP 65 SA
SPRING APPLIED, HYDRAULIC PRESSURE RELEASED
SINGLE ACTING DISC BRAKE
The Dellner Brakes Single Acting model SKP65-SA
is a spring applied, hydraulically released caliper disc
brake, that offers a reliable and safe method of
braking linear or rotary motion.
The Single Acting brake is largely designed with
internal parts from Dellner Brakes Double Acting
brake, the SKP, a well proven concept.
The Single Acting brake is self aligning and is thus
well suited for applications with axial movements
or limited installation space. Moreover, it consists of one cylinder halve and a robust low friction
sliding system that enables self alignment. The SA caliper concept also has a spring retraction system
that ensures full brake release and pad retraction from the brake disc, when the brake cylinder is
released with hydraulic pressure.
Cylindrical guide pins help direct the tangential force from the brake lining to the brake housing and
support. As a result, any radial forces on the brake piston is minimized which contributes to a longer
brake life.
The unique, well proven Dellner Brakes design, with the brake piston extended through to the
adjustment nut gives a visual indication when adjustment is required.

Dellner Brakes AB reserves the rights to modification without special notice.
As an option, the brakes can be equipped with proximity switches to indicate brake ON/OFF, PAD
WEAR and/or NEED OF ADJUSTMENT. Dellner Brakes also offers a variety of different friction
and seal materials to fit any application demands.
