ElroSeal™ PTFE Rotary Shaft Seals for High-Speed Applications

ElroSeal™ E was developed for use under very low friction, high speeds as well as pressures and dry running. This design also impresses with its high media and temperature resistance.

Features

• Good sealing function with pressurized media
• Suitable for dry running and lubricated operation
• Helix structure for alternating rotation directions
• Good dynamic and static sealing properties
• High performance, fluoropolymer sealing lip

Operating Parameters

• Recommended circumferential speed: 20 - 40 m/s
• Temperature range: -60 °C bis +200 °C
• Pressure: up to 20 bar (dimension and time dependent)
• Vacuum: up to 10^–3 mbar
• Center offset: ≤ 0,1 mm
• Concentricity tolerance: ≤ 0,05 mm

ElroSeal™ EM has a precisely matched spring support which ensures that the sealing lip does not lift off the sealing surface at very high circumferential speeds or shaft runout.

Features

• Good sealing function with pressurized media
• Good dynamic and static sealing properties
• Helix structure for alternating rotation directions
• High performance, fluoropolymer sealing lip

Operating Parameters

• Recommended circumferential speed: 40 - 60 m/s
• Temperature range: -60 °C bis +200 °C
• Pressure: up to 20 bar (dimension and time dependent)
• Vacuum: up to 10^–3 mbar
• Center offset: ≤ 0,125 mm
• Concentricity tolerance: ≤ 0,075 mm

ElroSeal™ SD was specially developed for highly dynamic sealing properties. Due to the double spring design, the seal can be adapted very well to the requirements and seals reliably even at extremely high speeds. At the same time, the seal produces very low friction.

Features

• Good dynamic and static sealing properties
• Helix structure for alternating rotation directions
• High performance, fluoropolymer sealing lip
• Very low friction

Operating Parameters

• Recommended circumferential speed: 60 - 100 m/s
• Temperature range: -60 °C bis +200 °C
• Pressure: up to 20 bar (dimension and time dependent)
• Vacuum: up to 10^–3 mbar
• Center offset: ≤ 0,15 mm
• Concentricity tolerance: ≤ 0,1 mm

ElroSeal™ SP, also known as Speedflon™, is a unique, patented sealing solution specifically designed for use in modern automotive supercharging systems. Using "state of the art" fluoropolymer sealing technology, combined with a pressure compensation diaphragm, this achieves exceptional sealing properties with very low friction.

Features
