WIPER PO20
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO20 sealing part combines an asymmetric lip seal profile with a wiper. Since it is installed in a single groove, the PO20 seal has several advantages:– reduced overall dimensions;
– faster construction of the groove.
TECHNICAL DATA
Pressure: < 20 bar Speed: < 1 m/s Temperature: from - 30° C up to + 90° C Fluids: air with or without lubrication, mineral oils or greaseMATERIAL
Standard polyurethane 90 Shore A.Alternative polyurethane 85 Shore A.
ASSEMBLING
Remove cutting edges and/or flashes from the housing where the wiper has to be installed in order to minimise seal wear during operation.
WIPER PO19
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO19 type rod guide ring is used to avoid direct contact between cylinder head and rod, and between piston and sleeve, since for the main part of the pneumatic cylinders are made of aluminium. It’s also used to lead all the system. The guide rings are in moulded, non-abrasive, selflubricant material, especially studied to improve the linear sliding. The profile presents chamfers both sides for easier installation of rod and piston.TECHNICAL DATA
Speed: < 1 m/s Temperature: from - 40° C up to + 115° C Static Strength: up to 36 N/mm2MATERIAL
Non abrasive modified Polyacetalic resin with additives improving the sliding.Advantages
– Excellent price/performance ratio
– Low stick-slip effect
− Good compressive strength
WIPER PO18
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO18 wiper type is commonly used in simple effect cylinders open on one side. Because of its cleaning function, a reverse profile wiper is used to prevent bore wearing which may be caused by atmospheric agents, condensation and other environmental conditions.TECHNICAL DATA
Pressure: no pressure, but a slight cavitation might occur.Speed: < 1 m/s Temperature: from - 35° C to + 100° C, with peaks till + 110° C Fluids: water, dust or other atmospheric factors
MATERIAL
The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2.ASSEMBLING
The assembling is done by overlapping in semi-open groove with a chamfer preventing the wiper extrusion during the cycle inversion. It is important to remove flashes or cutting edges to avoid damages.
WIPER PO3
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO3 bidirectional scraper has a combined scraper profile where the seal is provided with a scraping lip on the outside and a sealing lip on the inside. The dimensions are interchangeable with normal scraper housings. The scraping lip is very flexible and it compensate misalignments of the rod. The sealing side has a stronger and longer lip to ensure the sealing performance and to help the oil film remaining on the rod to go back into the cylinder.TECHNICAL DATA
Pressure: < 20 bar Speed: 1 m/s Temperature: from - 35° C to +100° C with peaks till +110° C Fluids: water at room temperature and mineral oilsMATERIAL
The proposed material is polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2.It is also possible to use harder polyurethanes for heavy polluted environments. In case please contact our technical department.
ASSEMBLING
The assembling is extremely easy because of the semi-open groove. Remove flashes an/or cutting edges in the housing.
WIPER PO15
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO15 wipers are made of a PTFE element and an O-Ring having a sealing effect in the static part and, at the same time has an energizing effect on wiper in the absence of pressure. The TRD also has a scraping effect on the outside of the Cylinder and maintains a residual oil film on the internal part of the rod. Used with proper sealing, allows the hydrodynamic return in the cylinder.TECHNICAL DATA
Speed: < 15 m/s Temperature: from - 30° C to + 100° C for the standard type with nitrile O-Ring. Short peaks till +120° C from -15°C to +150°C with FKM o-ringsMATERIAL
Bronze-filled PTFE for the standard type, and nitrile rubber NBR for the O-Ring.ASSEMBLING
Easy assembling in semi-open groove. The O-Rings have to be fitted first into the groove and Then the PTFE element. Remove flashes and/or cutting edges in the groove.
WIPER PO17
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO17 wiper can be self-aligned in case of rod misalignment during operations, thanks to its special profile and design,. It presents two lips and it’s similar to a seal: the scraping lip is longer, very flexible and dynamic; the static lip is shorter and stops the impurity sticking to the blocking step.TECHNICAL DATA
Speed: < 1 m/s Temperature: from - 35° C to + 100° C with peaks till +110° C Fluids: water at room temperature mineral oilsMATERIAL
The proposed material is polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2. It is also possible to use harder polyurethanes for heavy polluted environments. In case please contact our technical department.ASSEMBLING
The assembling is extremely easy because of the semi-open groove. Remove flashes an/or cutting edges in the housing.
WIPER PO4
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO4 scraper, unlike other profiles, has a step in the static side which hooks it to the housing. This helps automated assembling and makes the mechanical construction of the groove extremely easy. It presents notches in the wiper inner base having stabilisation effect, ensuring good ventilation. This avoids extrusion problems.TECHNICAL DATA
Speed: < 1 m/s Temperature: from - 35° C to + 100° C with peaks till +110° C Fluids: water at room temperature, mineral oilsMATERIAL
The material used is a very flexible polyurethane, even at low temperatures, with a high abrasion resistance. Standard polyurethane 90 Shore A up to diameter 35 mm (B0). For bigger dimensions standard polyurethane 93 Shore A (C0).ASSEMBLING
The assembling is much easier since it can be done in semi-open groove. Remove flashes an/or cutting edges in the housing.
WIPER PO2 – NBR
STANDARD SEAL DIMENSIONS
DESCRIPTION
The function of the PO2-NBR wiper is cleaning the rod while return into position, blocking external impurities. It is made up of an external, grinded metal cage core part glued to a NBR element. The groove is open and makes easier the design of the seat.TECHNICAL DATA
Speed: < 1 [m/s]] Temperature: - 30 °C . +100 °C mescola NBR Fluids: atmospheric factors ,water, sand,etc.
MATERIAL
The wiper material is a nitrile rubber NBR 90 Shore A with steel core AISI 1010.ASSEMBLING
The assembling is done in open groove. Remove flashes and cutting edges to allow better installation of the wiper. Warning: The housing of the wiper must be within the machining tolerance. Not observed tolerances may cause the extrusion of the product during the operations.

WIPER PO16
STANDARD SEAL DIMENSIONS
DESCRIPTION
The PO16 wiper has a high flexible wiping lip on the dynamic side and a strong, shorter, protruding lip on the static side. This special profile keeps the rod and the static side where it is housed free from any impurity, waste or water. Impurities would damage the seal and corrode the inner part of the cylinder.
TECHNICAL DATA
Speed: < 1 m/s
Temperature: from – 35° C to + 100° C with peaks till +110° C
Fluids: water at room temperature, mineral oils
MATERIAL
The material used is a polyurethane with a high modulus of elasticity, low compression set and high wear resistance. Its hardness is 93 Shore A ± 2.
ASSEMBLING
It is not very problematic as it can be done in semiopen groove located in the nearest part outside the cylinder. Remove cutting edges and flashes to avoid the scratching of the wiper during the installation.
