Products Description
FKM 65 rubber SC oil seal is a high-performance seal for applications requiring high temperature, oil, and chemical resistance. The SC oil seal is a low-pressure single-lip radial oil seal with a clamping ring spring and a rubber-covered outer diameter for improved outer diameter sealing capabilities.
Advantages
Sealing Performance: The SC oil seal features a single lip design with a garter spring, which enhances its sealing ability by maintaining consistent pressure against the shaft.
Thermal Expansion Compensation: The seal can compensate for thermal expansion and is suitable for environments with large temperature changes.
Rubber-Covered OD: The rubber-covered OD improves sealing against external contaminants.
Low-Pressure Operation: Designed for low-pressure applications (up to 7 psi), these seals are ideal for systems where high pressure is not a concern.
Materials and Construction
- Material: Made of FKM (fluorocarbon rubber), it has excellent heat, chemical, and oil resistance for use in demanding environments.
- Design: Features a single lip design and ring spring for enhanced sealing capabilities. The outer diameter (OD) is covered with rubber to improve sealing performance against the housing.
Performance Specifications
Pressure Rating: Maximum operating pressure is 7 psi, suitable for low-pressure applications.
Surface Speed: Can handle surface speeds up to 2000 ft/min, indicating its efficiency in dynamic applications.
Temperature Range: Operates effectively in temperatures ranging from -22°F to 400°F (-30°C to 204°C).
Recommended Applications
Commonly used in:
Gearboxes
Pumps
Electric motors
These applications benefit from the seal's durability and resistance to various lubricants and environmental conditions.
Limitations
Since there is no exclusive sealing lip, SC oil seals are not recommended for use in polluted environments, which could result in contaminants entering the sealing area.
