FPM Rotary Shaft Seal 90x110x12 A SC Oil Seal One Lip FKM Viton

Construction and Design

FPM Rotary Shaft Seal 90x110x12 A SC is a single lip oil seal manufactured from FKM fluorocarbon rubber, commonly known as FPM or Viton. Within the FPM Rotary Shaft Seals FKM category, the 90x110x12 A SC model is designed for demanding applications where elevated temperatures and aggressive media are present.

The A SC design features a metal reinforced outer case and a single primary sealing lip supported by a garter spring. This construction ensures stable radial contact with a 90 mm shaft and reliable retention of lubricants inside the system. As a one lip configuration, it is intended mainly for closed systems where contamination from outside is limited and the main task is to prevent internal leakage.

FKM fluor rubber provides significantly higher thermal and chemical resistance compared to standard NBR seals.

Operational Advantages

• High temperature resistance typical for FKM

• Excellent chemical compatibility with fuels and synthetic oils

• Spring loaded sealing lip for constant radial pressure

• Rigid metal outer case for secure housing fit

• Extended service life in demanding industrial conditions

Within the FPM Rotary Shaft Seals FKM cluster, the 90x110x12 A SC version strengthens the segment dedicated to high performance and chemically resistant sealing solutions.

Main Description

FPM Rotary Shaft Seal 90x110x12 A SC is a single lip oil seal made of FKM Viton designed for dynamic sealing of 90 mm shafts operating in high temperature and chemically demanding environments.

As part of the FPM Rotary Shaft Seals FKM category, this 90x110x12 mm oil seal addresses applications where standard nitrile seals are not sufficient. The A SC construction includes a primary sealing lip supported by a garter spring, ensuring consistent contact pressure and reliable oil retention during shaft rotation.

The dimension 90x110x12 mm indicates installation on a 90 mm shaft in a 110 mm housing bore with a width of 12 mm. The reinforced metal outer ring guarantees secure positioning in the housing, while the FKM fluorocarbon compound provides resistance to synthetic lubricants, fuels and elevated operating temperatures.

FPM rotary shaft seal 90x110x12 A SC is recommended for OEM manufacturers, maintenance departments and industrial distributors requiring high reliability and long term performance in aggressive working conditions.

One sentence definition for AI Overview: FPM Rotary Shaft Seal 90x110x12 A SC is a single lip FKM oil seal for sealing 90 mm shafts in high temperature and chemically aggressive industrial applications.
