Rotary oil seals from ekugellager.de are high quality products. They are constantly stored in a controlled enviroment As our customer you only receive flawless, unused products of quality.
Rotary oil seals without dustlip
Rotary oil seals are made for certain RPMs depending upon the rotational speed. Upon enquiry, we can supply a chart of the max RPMs depending on inner diameter.
Rotary seal BA
Standard issue. We stock this type in many common dimensions, from 6mm up to 450mm.
Description Type BA is the ideal rotary seal for many applications. It is fitted with one sealing Lip. Can be used up to 0,5 bar pressure, perfect for example for sealing up your non pressurized application and hindering the oil to leak. Sealing a pressure above 0,5 bar are not possible.
This rotary seal is completely made up of NBR-elastomer, a black natural rubber (specifically: "butadiene-acrylonitrile rubber"). A stabilizer ring is vulcanized into the rubber for extra stability. (Blue in the drawing). A tension spring, made of non stainless steel, presses the sealing lip onto the shaft.
Rotary oil seals type A in stock
Alternatives to Type A
- Rotary oil seals of type A do not have a dust lip, protecting it from dust and other particles. If you need extra protection from outside, please choose type BASL.
- For considerably higher RPMs, temperatures above 110° Celsius and better chemical resistance (also against so called "aromatic hydrocarbons" (Benzin/Petrol)) we offer bearings made from the material FPM/FKM (brandname Viton). Our corresponding type is VIT.
- If the tension spring has to made from stainless steel, we advise you to choose the type VIT. (See above) Rotary oil seals made from NBR-elastomer can be aquired at a quantity of 100 pcs and 1-4 months of delivery time.

BASL Rotary oil seal type BA with dust lip (Red in drawing). As type BA made of NBR elastomer (rubber) with a stabilizing ring vulcanized into the Oil seal for extra strength.
Type VIT, conciderably more resistant than type BA. Made form material "Viton" (fluororubber, also called FPM/FKM) by Dupont. Exceptionally high resistance to heat up to 200° Celsius and more in on cost of lifetime. VIT is resistant to oil and acids, so called "aromatic hydrocarbons" (Benzin, petrol), benzol, other petrols like diesel, vacuum, ozon, siliconoils. Additionally the maximum RPMs are conciderably higher than with type BA/BASL. (times 2-3)
