RD-11

Radial RD-11

Description

The radial direction type RD-11 is a PTFE seal with an NBR O-ring, which is outer-facing. The RD-11 radius direction is a double-acting seal and always consists of a PTFE seal and an NBR O-ring. The seal is close to the outside. The sealing surface is specially designed for use at high pressure and low speeds. The grooves in the dynamic sealing surface provide the possibility of forming a lubrication film. This reduces friction and is still protected by dry running.

PTFE carbon/graphite, for rotating and oscillating movements, outside sealing

Sealing element: PTFE, O-ring, material: NBR 70

Application parameters

Medium

Hydraulic oils according to DIN 51524 part 1 - 3, lubricating oils, mineral based lubricants, highly flammable hydraulic fluids HFA, HFB, HFC according to VDMA 24317, water and water-oil emulsions.

Applications

• For sealing of hydraulic rotation
• Sealing of reciprocating or rotating rods / axes

Installation

For smaller diameters, the installation requires an open installation space. For larger diameters, the seals can be mounted in a closed installation space.

Subsequently, calibration is necessary.

Note

At pressures > 10 MPa it is recommendable that for the cross section you choose the next larger profile available. Please contact us for furter information.

We can also produce this radial seal on request in the materials below. This is our type DR116.
