The cylinder piston rod seal wiper ET applies to anti-twist cylinders. Compared with the EU circular inner hole, the hole is oval ET. It combines three functions: sealed, dust-proof, fixed.
By integral molding, and after years of using the P5008 polyurethane material validated, ET has the following advantages:
• Only one ring can play a dual role of seals and dust
• Low assembly costs, reduce inventory requirements.
• The minimum space requirements to ensure that all the features you need.
• difficult to corrosion, by the positioning ring and the dust seal combination eliminates the need for metal snap ring.
• dust seal parts of special design, to avoid dust accumulation.
• Due to the unique design using dynamic sealing lip and polyurethane material, making it less friction and longer life.
• After the initial assembly lubrication, even with dry and oil-free air is also having a very long service life.
Applications
For preventing the rotation of the elliptical cylinder rod seal.
Working Pressure: 10bar
Working temperature: -35 to + 80 ℃
Surface speed: 1m / s
Medium: lubricated air as well as dried and oil-free air (after initial assembly lubrication).
Material
Standard materials: P5008, polyurethane materials (Shore Hardness 94 A)
Temperature materials: P5009, polyurethane materials (Shore Hardness 94 A)
Installation
ET loaded with DIN 7993 (B type) standard annular groove undercut in, and its outer diameter of the flange is fixed in the groove.
During assembly to avoid seal / dust lip is a sharp edge damage. Guide rod and seal the bore surface must be positive.
For special requirements (temperature, speed, used for water, HFA solution, HFB fluid, etc. medium), please contact our service department in order to recommend appropriate materials and structures.
The above data are in standard materials and standard media measured. Require specific temperature range depending on the application conditions.
