Piston seals with rigid split slide rings
These SKF piston seals have a rigid split slide ring made of glass fibre reinforced polyamide and a nitrile rubber (NBR) energizer. The rigid slide ring has high resistance to wear and gap extrusion. The slide ring also provides low friction, even at high pressures. The split slide ring design facilitates the installation process into a closed housing.
CUT profiles (fig. 1) have a step cut slide ring and a rectangular energizer. They are suitable for pressures up to 500 bar (7 250 psi) in heavy duty applications. CUT profiles are available in metric sizes (→ Size list [pdf]) and some fit seal housings in accordance with ISO 7425-1:1988. For additional information, refer to CUT profile data.
They also can be used for short pressure pulses and shock loads with proper system design. For additional information, contact SKF.
SCP profiles (fig. 2
) have a step cut slide ring and an oval energizer. They are suitable for pressures up to 690 bar (10 000 psi)
in heavy duty applications and are available in inch sizes (→ Size list [pdf]). For additional information, refer to SCP profile data
