Radial Seals for Translational Movements

Sealing of Hydraulic Rotary and Oscillating Movements

RPOR radial seals are seals that can be pressurized on both sides. They are used when high pressure loads occur in combination with translational movements. They consist of an elastomeric O-ring for pre-tensioning and a PTFE sealing element that is either internally sealing (RPORI32) or externally sealing (RPORA32). These radial seals often occur in double arrangements. The grooves running around the dynamic sealing surface allow lubricants build-up and reducing friction. The surface is specially designed for high pressure and low speed applications.

Benefits at a Glance

Reduced friction and therefore good lifetime
Good resistance against oils, lubricants, greases and hydraulic fluids
Withstands high pressures at low speeds
Improved emergency running properties
Very good price-performance ratio
Suitable for many industrial applications

Important note: Dichtomatik products comply with common industrial standards and therefore are suitable for many applications excluding safety-critical ones like Automotive. Premium Freudenberg products are the right choice for all applications ensuring highest quality and safety standards and therefore optimal total cost of ownership.

Out of Two Types

RPORI32: PTFE bronze sealing element with a NBR O-ring as pre-tensioning element for sealing hydraulic rotary transmission feedthroughs and swiveling or rotating shafts and rods; internal sealing
RPORA32: PTFE bronze sealing element with a NBR O-ring as pre-tensioning element for sealing hydraulic rotary transmission feedthroughs and swiveling or rotating shafts and pistons; external sealing

Please note that resistances, pressures and temperatures are mutually influenced by various parameters.
