Help - 20 mm shaft seal?

WyeBee on Thu January 07, 2010 8:26 AM User is offline

Refrigerant Type: R134a

Hello to the forum!

A challenge here - I am from a small startup that is currently working on a compressor, and we need a standard shaft seal for a 20 mm shaft. (R134a)
Unfortunately, compressor seals do not publish the seal mechanical data...
Has anyone seen a 20mm shaft on any model? if we know the model, we can order the seals.

Thanks!

It would help if you give the year, make and model of the car, if it's not for a car, then give what ever info you can..

Post a picture of the compressor as well as the application you are working with. A picture says a thousand words…

As it is not a car, I have no model to show...
We are designing the housing around the shaft, so we are really flexible with the type of seal. The shaft is 20 mm in diameter and hence the requirement. We talked with seal companies, but it is going slow.
So, basically, any seal with a 20 mm inner diameter of a R134a compressor will do.
Thanks!

My shaft seal sources list the seals by application. No shaft measurements are provided. Might be best to contact a re-builder as they may have data on the shaft size of each individual compressor.

A bit of internet research should indicate many manufacturers of the parts you area seeking. There are numerous suppliers located both here and 'off shore'. Many offer engineering services and will make custom applications.

Basic dimensions of a seal is ID, OD, and thickness, but is it really worth fooling with a compressor you know knowing about?

Automotive seal manufacturers simply request the car model in order to fit the seal and do not provide the ID of the seal. We are, in parallel looking for a custom seal, but prefer a simple standard one.

You seem hesitant about posting a photo of your compressor. See upload image window to the above right, upload your image and paste the URL into your next post. Take three shots, front, side, and end view. If you want help, have to do your part.
