These innovations have created one of the highest-performing and most versatile seals found anywhere. The Simmerring® is known not only for being the original oil seal but one of the top performing with excellent wear, aging, and media resistance all while being easy to install.
- Incredibly reliable functionality and long service life
- Superior performance increases the operational efficiency of your equipment
- Easy mounting of the Simmerring® reduces downtime
- High level of adaptability to temperature, pressures, media, and more
Standard program Simmerring®:
Offers high-quality performance with extreme versatility due to the amount of variations such as size the standard Simmerring® offers allowing it to be utilized in a wide range of applications ranging from gearboxes, axels, or pumps to motors.
Premium Sine Seal (PSS):
With its unique design and sealing behavior offers over double the service life of a standard sealing system. This design also improves the performance of the equipment thanks to its ability to reduce friction, power loss and actively counteract internal contamination within the sealing system.
These are a combination of a Simmerring® and an optimized wear sleeve that is used in applications where they are exposed to high stress such as construction or agricultural equipment. Thanks to advanced elastomers it is possible to achieve optimal sealing performance without a spring because of its ability to reduce friction and withstand high temperatures.
75 FKM 260466:
This material is made of fluoro rubber that was specially developed for use in synthetic oils and polyglycols. This sealing material is very wear resistant which increases service life and performs very well in applications with challenging lubricants such as power transmissions.
Medium pressure seals BABSL and PPS
The medium-pressure seals BABSL and PPS have been used as standard in many applications with high pressures for decades. PPS also offers the additional advantage of exceptional performance in ranges above 1.5 bar and at high circumferential speeds.
Oil Seals MSS 1
This is a modular sealing system that is used for industrial applications such as gearboxes. With its special design, it protects against wear and dirt inside the sealing system. It also allows for sealing to function with low-viscosity or gaseous media by securely sealing to the housing hole.
Applications & Industries
Thanks to the diversity of sizes, designs, and materials that the Simmerring® is available in it can be used in a truly massive amount of applications. Below are a few examples of the most common applications you can find Simmerring® seals in use today.
Simmerring® Modification abilities
To even further the versatility of the Simmerring® Freudenberg-NOK Sealing Technologies offers a range of modifications from adjustments to sealing lips, additional support rings, dust lips, backup rings, or conductive elements.
