the RS07 seal is designed  for use as a rod seal.

area of application: hydraulics

• reciprocating rods on hydraulic cylinders,push rods, fittings.
• as rod seals for switching functions (e.g.clutch operation).
• as rod seals for clamping seals.
• replacement for rubber fabric compact seals.

note

• under certain operating conditions, this seal may “pump” via the trailing side, i.e. as it does not fit tightly on the outside diameter, small amounts of operating  media may be pressed out when the seal is deformed  under pressure which may appear to be leakage.
• the ratio between nominal width and sealing height cs/H should not drop below  a value  of 1/1.25 (essentially according to ISO 5597 housings for piston and rod seals).
• high friction.
• high break-awaymoment.
• the recovery capacity is smaller than with simple lip rings.
• cross-section limited to 20 mm.
• not suitable for new designs (prefer the more modern RS03 type).

function

RS07 profiles are lip seals designed  to seal pressurised space against the atmosphere;  mainly for reciprocating movements. the design

is based on application in standard hydraulic systems with conventional hydraulic oils. the operating parameters are as defined in the

sealing data sheet and material data. requirements deviating from these parameters can be met to a certain degree by changing the

geometry in the software program.

for detailed information regarding chemical resistance please refer to our „list of resistance“. for increased chemical and thermal resistance rubber

materials are to be preferred, attention  should be paid to restrictions for pressure range and wear resistance. for higher gliding  speeds another system should be used (e.g. PTFE materials).

note on special materials:

other materials such as Viton, Silicone, EPDM, H-NBR, etc., can be used for the preload element, but they are only useful in specific cases (temperature or

chemical influences).

Description

the rod seal RS09-D is an rubber  energised plastic faced seal. the seal is designed to expand and improve the service parameters of O-Rings and is installed in existing O-Ring grooves.

RS 09-D combines the flexibility and response of O-Rings with the wear and friction characteristics of the PTFE+.... materials in dynamic applications.

the figures below shows the cross section of the RS09-D.

the double acting performance of the seal follows from the symmetrical cross section which allow the seal to respond to pressure in both directions.

initial contact pressure is provided by radial compression of the O-Ring. when the system pressure is increased the O-Ring transforms this into additional contact pres- sure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.

the RS1012 seal is designed for use as a rod seal.

area of application: hydraulics

• reciprocating rods on hydraulic cylinders; small swiveling motion also permissible.
• especially for heavy hydraulic applications or heavy-dutyoperating conditions.
• for repairs of heavy machinery and for normal wear,when re-tightening is possible.

note

• expensive and complex design.
• high degree of friction and thus little mechanical efficiency.
• for small numbers.for large amounts, the RS1012 profile is preferred.
• too many chevrons or too high clamping torque at installation can load to increased friction and wear (for standing applications usemaximum 3-4 chevrons).
• if a split version is used,the packings must be made slightly larger (approx. 1% in the diameter). the packing as well as the pressureand male ring are cut straight. at least 3 packings should be provided, preferably  5.

function

RS1012 profiles are single-acting rod chevron sets designed to seal pressurized space against the atmosphere; mainly for reciprocating movements. the design is based on application in standard hydraulic systems with conventional hydraulic oils. the operating parameters are as defined in the sealing data sheet and material data. requirements deviating from these parameters can be met to a certain degree by changing the geometry in the software program.

operating parameters & material  (max. pressure=500 bar (50 MPa))

the stated operation conditions represent general indications. it is recommended not to use all maximum  values simultaneously. surface speed limits apply only to the presence of adequate lubrication film.

1 pressure ratings are dependent on the size of the extrusion gap.

for detailed information regarding chemical resistance please refer to our „list of resistance“. for increased chemical and thermal resistance rubber

materials are to be preferred, polyurethane materials increase wear resistance. for higher gliding speeds another sealing system should be used (e.g. PTFE materials).

gap dimension

when using a pressure ring, the extrusion gap is already integrated  in the seal. the gap between piston rod and housing should not exceed cs·0.05.

manufacturing notes

the following nominal widths are preferred. the theoretical packing height SH11 should be designed in accordance with the recommended values;

 in order to be able to maintain the required height irrespective of the accumulated packing height ‘h’, the pressure ring is individually adjusted during the production of the V-packing set. to do so, a control dimension  is provided  by the machine  software with a view to assisting this process.

 surface quality

 tolerance recommendation

 mode of installation

insert the male ring first, then the packing  and finally the pressure ring (well greased)  into the installation  space. insert the metal insert without load, complete mounting of the system, tighten metal inserts slightly, let run in (10 to 20 idle strokes); re-tighten depending  on leakage. in the case of wear, re-tightening is also possible.

if split seals are used, the packing should be fitted by separating the split ends axially (twisting). joints should be staggered by 90 to 120 degrees relative to each other. split ends should be inserted into the groove first and then the remainder  of the seal is pressed in.

recommended mounting space:

the adjustment range of the mounting space height (L) should correspond to approx. 10% of the theoretical mounting length. a guideline for the height of the spacer should be approx. 30% of the cross section.

recommended guide tolerance D1:

insertion chamfer:

in order to avoid damage  to the rod seal during installation, the piston rod is to be chamfered  and rounded  as shown in the “recommended mounting space” drawing. the size of chamfer depends on the seal type and profile width.
