Cross-sections of CNC-turned seals

The cross-section overview helps to preliminarily select a turned seal profile. Final selection depends on the application, gland dimensions, medium and system parameters.

Profile
174 cross-sections
Kategorie
8 functional groups
Mode
custom CNC solutions
01

Profiles for piston, rod, wiper, static, rotary and guiding applications.

02

Geometry can be modified for a specific gland or atypical operating conditions.

03

Profile selection for hydraulics, pneumatics, rotary motion and special applications.

How to use the catalog

  • select the seal function in the system: piston, rod, wiper, guiding or rotary motion
  • compare the visible cross-section with the existing seal or the required gland
  • provide the profile code, dimensions and operating conditions (medium, pressure, operating temperature, single- or double-acting) to confirm material

What we confirm during selection

  • diameters, gland width and single- or double-acting operation
  • pressure, temperature, medium and movement speed
  • profile material: PU, NBR, FKM, PTFE or a special solution

Process

How we handle an inquiry

01 Choose function

First determine whether the profile works on the piston, rod, as a wiper, static, rotary, back-up or guiding element.

02 Compare the cross-section

Match the profile code with the existing seal, gland or expected operating geometry.

03 Provide conditions

Dimensions, medium, temperature, pressure, motion and expected material are needed for confirmation.

04 Confirm production

Based on this we select the profile, material and any geometry changes for the specific operating conditions.

Technical selection

Data needed for inquiry

If you do not have complete data, send a photo of the part, groove dimensions or operating conditions. We will help determine the missing parameters.

  1. profile function: piston, rod, wiper, guiding, static or rotary motion
  2. diameters, gland width, clearance and available mounting space
  3. medium, temperature, pressure, movement speed and number of cycles
  4. photo, sketch or cross-section code from the profile catalog

FAQ

Frequently asked questions

Is the profile code sufficient for a quote?

The profile code speeds up selection, but dimensions, material or operating conditions and quantity are also required for a quote.

Can the cross-section be modified?

Yes. For CNC-turned seals the geometry can be adapted to a specific gland if operating conditions and material allow.

Do you select the material for the profile?

Yes. Based on the medium, temperature, pressure and type of motion we recommend the material and execution variant.
