FPM Rotary Shaft Seal 55x75x10 SC Single Lip

Applications

The FPM Rotary Shaft Seal 55x75x10 SC is a single lip oil seal designed for rotary shaft sealing in demanding industrial applications. It is commonly used in gearboxes, engines, pumps, compressors, and industrial machinery where resistance to oils, greases, and elevated temperatures is required. The SC single lip design ensures reliable rotary shaft sealing with stable contact and low friction.

Material and Advantages

Manufactured from FPM (FKM) elastomer, this seal provides excellent resistance to mineral and synthetic oils, lubricants, fuels, and high temperatures. Compared to standard NBR seals, FPM offers superior thermal stability and longer service life. The SC design is suitable for applications where a dust lip is not required, focusing on precise oil sealing and durability under continuous operation.

Main Description

The FPM Rotary Shaft Seal 55x75x10 SC is a high-quality technical sealing component engineered for long-term use in harsh industrial environments. The single sealing lip maintains consistent contact with the shaft, effectively preventing oil leakage while minimizing friction and wear. The FPM compound ensures stable elasticity and sealing performance even under continuous exposure to elevated temperatures and aggressive media.

This oil seal is widely selected for applications where conventional rubber seals are insufficient due to thermal or chemical stress. As a reliable single lip rotary shaft seal, it supports extended maintenance intervals, protects critical machine components, and contributes to overall system reliability. Suitable for OEM installations as well as maintenance and overhaul operations.

FAQ - Frequently Asked Questions

What does SC mean in rotary shaft seals?
SC indicates a single lip oil seal without a dust lip, designed for oil retention.

Why choose FPM instead of NBR?
FPM offers significantly higher resistance to temperature, oils, and aggressive chemicals.

Is this seal suitable for continuous operation?
Yes, it is designed for long-term industrial use under demanding conditions.

How do I select the correct seal size?
Match the inner diameter to the shaft, outer diameter to the housing, and width to the available space.
