R3 Rod Seal
Descriptions
The profile R3 rod seal is a sealing element of compact design with a special antiextrusion ring.
The main advantages of this combination are smooth running, excellent sealing performance and high wear resistance, even under exceptionally hard working conditions.
These rod seals guarantee a leakfree performance even at low pressures or when rod
movement occurs without pressure.
Features
• Enhanced sealing performance in nonpressurized conditions.
• Good wear resistance.
• Insensitive to pressure peaks.
• High temperature resistance in case of
suitable compound selection.
• Improved lubrication due to pressure
medium deposit in the dynamic contact
area.
• High extrusion resistance.
• Excellent media resistance in case of
suitable compound selection.
• Suitable compounds available for
special requirements of the chemical
process industry.
• Suitable compounds available for special requirements of the food processing
industry.
• Dimensions according to ISO 5597.
• Installation in closed and undercut
housings.
Range of application
Seals for piston rods in hydraulic cylinders.
Operating pressure | ≤ 315 bar |
Operating temperature | -30 °C to +100 °C |
Sliding speed | ≤ 0.5 m/s |
Compounds
Rubber part:
Standard: N3544, NBR compound (≈ 88 Shore A).
For high temperatures: V3664, FKM compound (≈ 85 Shore A).
Glide ring: Polon® 062, modified PTFE + 60 % bronze.
Installation
This rod seal profile R3 is manufactured with a slightly oversized outer diameter, thus
ensuring a tight fit in the groove. The preload at the inner diameter necessary for the
functioning of the seal will only be generated after installation.
The working life of the seal is mainly influenced by the max. gap at the pressureopposite of the sealing element.
