Surface roughnessSurface roughness DIN EN ISO 4287The functional reliability and service life of a seal dependto a very great extent on the quality and surface finish ofthe mating surface to be sealed.Scores, scratches, pores, concentric or spiral machiningmarks are not permitted. Higher demands must be madeon the surface finish of dynamic surfaces than of staticmating surfaces.The characteristics most frequently used to describe thesurface microfinish Ra a , R z and R max are defined in DINEN ISO 4287. These characterics alone, however, are notsufficient for assessing the suitability in seal technology. Inaddition the material contact area of the surfaceroughness profile R mr in accordance with DIN EN ISO4287 should be demanded. The significance ot thissurface specification is illustrated in Fig. 4. It shows clearlythat specification of R a and R z alone does not describe thesurface roughness profile accurately enough for the sealtechnology and is thus not sufficient for assessing thesuitability. The material contact area R mr is essential forassessing surfaces, as this parameter is determined by thespecific surface roughness profile. This in turn is directlydependent on the machining process employed.Busak + Shamban recommends that the followingsurface finishes be observed:Surface profileclosed profile formopen profile formFigure 2Profile forms of surfacesR a R z R mr0.1 1.0 70%0.2 1.0 15%Figure 4 shows two surface profiles, both of which exhibitnearly the same value for R z in the test procedure. Thedifference becomes obvious only when the materialcontact area of the survace roughness profiles arecompared. These show that the upper roughness profilewith R mr = 70% has the better seal/mating surface ratio.Table VSurface roughnessSurface roughness mParameterMating surfaceGroovePolyurethanesurfaceR max 1.00 - 4.00 < 16.0R z DIN 0.63 - 2.50 < 10.0R a 0.10 - 0.40 < 1.6The material contact area R mr should be approx. 50 to70%, determined at a cut depth c = 0.25 x R z , relative toa reference line of C ref. 5%.6

Rod Seal - Type ARUPRod seal type ARUPDescriptionThe ARUP rod seal has been redesigned with respect tothe traditional u-profile used in pneumatics to givesignificant improvements.These include: A dynamic lip with no sharp edges to facilitatessliding. Increased depth within the u-profile toincrease flexibility. The use of a urethane resin instead of rubber toincrease seal life and facilitate the use of nonlubricatedair.Technical dataOperatingpressure:Speed:Temperature:Media:Material1.6 MPa 1 m/sfrom -30 C to +80 CDry or lubricated air, mineral oils andgreases, non-aggressive gasesInstallationIt is important to remove all sharp edges from the grooveand shaft to prevent damaging the seal.The seals can be installed more easily if they are greasedor oiled.Ordering exampleRod Seal,type ARUPRod diameter:Groove width:Part No.:Material No.:d = 50 mmL = 7.5 mmARUP00500 (Table VII)WU9E1 (standard)Order No. ARUP0 0500 - WU9E1Serial No.Rod diameter x 10Quality index (standard):Material CodeThe standard material is a polyurethane with a very highwear resistance and good flexibility at low temperatures.Standard Material Polyurethane, 90 Shore A,Material No.: WU9E1Alternative MaterialPolyurethane, 85 Shore AMaterial No.: WUBE17

Piston Seal - Type APDSPiston seal type APDSDescriptionThe seal type APDS has been specifically designed for useon single acting short stroke cylinders with spring return,having a good guiding system. It has the same profile asthe APDE type, but its difference, is in the lower pre-loadon the external diameter which reduces both the frictionand the break-out pressure.Ordering examplePiston Seal,type APDSPiston diameter: D = 20 mmGroove width: L = 3 mmPart No.: APDS00200 (Table X)Material No.: WU9E1 (standard)Technical dataOperatingpressure:Speed:Temperature:Media:1.6 MPa 1 m/sfrom -30 C to +80 CDry or lubricated air, mineral oilsand greases, non-aggressive gasesOrder No. APDS0 0200 - WU9E1Serial No.Piston diameter x 10Quality index (standard):Material CodeMaterialThe standard material is a polyurethane with a very highwear resistance and good flexibility at low temperatures.Standard Material Polyurethane, 90 Shore A,Material No.: WU9E1Alternative MaterialPolyurethane, 85 Shore AMaterial No.: WUBE112

Cushioning Seal - Type AICMCushioning seal, type AICMDescriptionThe cushioning seal has been designed specifically foruse in braking systems at the end stroke of the piston, inpneumatic cylinders.The profile eliminates the limitations in this particularapplication that some seal types, like O-rings and lipseals have.The inlet chamfer on the sealing lip and the groove on thesealing border at the bottom makes the cushioning veryeffective.Another advantage is the utilisation of polyurethane,which with its high impact and abrasion resistance givesthe part a very long life.Technical dataOperatingpressure:Speed:Temperature:Media:1.6 MPa 1 m/sfrom -30 C to +80 CDry or lubricated air, mineral oils andgreases, non-aggressive gasesOrdering exampleCushioning seal,type AICMRod diameter:Groove width:Part No.:Material No.:d = 20 mmL = 7 mmAICM00200 (Tab.

Wear RingWear ring in modified POM for piston and rodDescriptionThe wear ring has the twin function of guiding the pistonor the rod in a cylinder and of absorbing transversalforces in it.At the same time, the metal contact between the slidingparts of the cylinder (piston and bore or cylinder rod andcylinder head) must be avoided.The wear ring in modified POM material has beenspecifically designed for the use on such pneumaticcylinders.The ring is available for a wide range of standarddimensions (see tables XXIV and XXVIII, page 36 and 39).Other dimensions are available on request.The serial No. for wear rings in modified POM are listedin the following table.Table XXSerial numbers for injectionmolded wear rings inmodified POMPistonRodGrooveRingserial No. serial No. widththicknessL 2WGP41 GR41 2.50 1.55GP43 GR43 4.00 1.55GP48 GR48 8.20 2.00GP49 GR49 9.70 2.00GP51 GR51 10.00 2.00GP53 GR53 15.00 2.00GP54 GR54 20.00 2.00GP55 GR55 25.00 2.00GP56 GR56 30.00 2.00All wear guide rings have chamfered edges, in order toavoid undesired edge forces in the corner radii of thegrooves.The choice for the correct size of the ring can be based onthe following formula:F x fh = ———d x pwhere the meaning of the letters are the following:p = admissible pressureF = radial loadf = safety factord = average guide diameterh = guide widthMaterialPOTBNThis compound in polyacetal was specifically formulatedfor pneumatic cylinders made in aluminium.Advantages: Good price/performance ratio High compressive strength Very good sliding effect in dry conditions Good resistance to abrasion Low stick-slip effect Simple installation also in closed grooves Long life32
