RS-31

RS-31

Description

The RP-31 is a two piece single acting rod seal which consists of a reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element and one thermoplastic back-up ring.

Product advantages

• functions even with poor surfaces
• improved sealing gap thanks to the active back-up ring
• reinforced cotton fabric base prevents the seal from extrusion
• both rod and piston application
• good sealing at low pressures
• Improved sealing gap due to the active back-up ring

Applications

Mining equipment, after market, mobile hydraulics, presses and standard cylinders.

Operating conditions

Note: The above data are maximum values and cannot be used at the same time.

Surface roughness

Note: It is recommended to have 50% to 90% of the working surface value.

Installation

The RS-31 is to be assembled into open grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

permissible sealing gap

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
