Products / Parker / Seal and O-Rings / Rod Seal/Wiper Praedifa Series EM, Ultrathan®
Rod seal and wiper for pneumatic cylinders. U-cup design. Short axial length.
The EM rod seal/wiper ring for pneumatic
applications is a proven combination element for sealing piston rods
in compact pneumatic cylinders and valve lifters. The special design
using a wear-resistant Ultrathan® compound enables installation in
smallest grooves for extremely low break-away and dynamic friction.
• Due to application-optimized geometry and compounds suitable for
use in oiled as well as in oil-free air (after initial lubrication
on assembly).
• Bi-functional element: seal and wiper.
• Extreme wear resistance.
• Low static and dynamic friction thanks to miniaturized design.
• Smooth running due to optimum adjustment of the functional lips.
• Smooth running due to optimum lubricant-retaining sealing lip
geometry.
• Excellent media resistance in case of suitable compound selection.
• Short axial assembly length.
• Short radial assembly depth.
• Installation in closed and undercut housings.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve
favorable friction coefficients and long service life.
