Characteristics
SWA-Wear rings are fabric reinforced phenolic resin wear rings for pistons providing excellent resistance against pressure load and installable in one piece groove and prevent metal seizing and/or deterioration of metal surface.
SWA-Wear rings best fit to low pressure hydraulic and pneumatic cylinders.
