FPM Rotary Shaft Seal 300x340x15 TC Oil Seal

Applications

The FPM Rotary Shaft Seal 300x340x15 SC is engineered for demanding industrial sealing applications involving rotating shafts where retention of lubricants and exclusion of contaminants are critical. These seals are commonly used in industrial gearboxes, pumps, motors, compressors, agricultural machinery, and heavy duty equipment. Constructed from high-performance fluorocarbon elastomer (FPM/FKM), this single-lip oil seal provides reliable sealing against oil, grease, fuel, and many aggressive media across a wide temperature range. Radial shaft seals like this are essential in systems where fluid retention, reduction of leakage, and protection from dust and moisture directly impact operational uptime and equipment longevity.

Advantages

Manufactured from FPM (FKM/Viton-type) elastomer, the seal exhibits superior chemical resistance and thermal stability compared to standard rubber seals. This results in enhanced durability in oil-contaminated and high-temperature environments, reducing maintenance frequency and downtime. The single-lip SC design ensures effective sealing at the shaft interface while maintaining low friction and minimal wear during rotation. Fluoroelastomer seals are preferred when extended service life and resilience to fuels, oils, and oxidizing agents are required. The radial lip geometry coupled with a stable elastomer compound provides robust sealing performance under dynamic conditions.

Product Description

The FPM Rotary Shaft Seal 300x340x15 SC Oil Seal One Lip is a professional-grade radial shaft sealing solution for industrial OEM and maintenance applications. Designed to meet the stringent requirements of rotating machinery, this seal features a resilient fluoroelastomer compound (FPM) that offers outstanding resistance to oil, heat, fuel, brake fluids, and many chemical agents. The single-lip radial design ensures effective sealing against leakage while maintaining low friction along the shaft surface during rotation.

Rotary shaft seals of this type serve a critical role in machinery reliability, preventing lubricant loss from housings and safeguarding internal components from external contaminants like dust, moisture, and particulates. The SC configuration facilitates straightforward installation and serviceability, making it suitable for both new equipment manufacturing and field replacement scenarios.

With a precise 300x340x15 specification, this seal fits applications where larger diameter radial seals are required. Its robust material properties and sealing geometry are optimized for dynamic applications involving moderate shaft speeds and rotational loads. This product supports operational continuity in heavy industry, reducing wear, extending equipment life, and improving overall system efficiency.
