1. Description
SC type oil seal is a single lip outer rubber skeleton oil seal. Compared with TC type, it lacks a dustproof lip. It is suitable for sealing in dust-free environment.
2. Materials
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.
FKM (fluorinated rubber)
Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems.

Description:
The SC is a low-pressure single lip radial oil seal with a garter spring. composed of a single metal cage with a rubber coating and a primary sealing lip with integrated spring. The rubber covered OD improves the OD sealing ability. the combined inner shell is designed to enhance the rigidity of the oil seal. It is especially suitable for larger sizes of oil seals with a back fit for sealing. The internal face of the steel case is not fully rubber covered. This seal is not recommended for use in a polluted environment as it contains no exclusionary sealing lip. To maximize performance over the lifetime of the seal an adequate lubricant should be applied under the sealing lip. SC profile is interchangeable with shaft seals A, G, A10, HMS4, WA, 92, 827N, DG, 35, IE, R21, BA, CB, ST, TG and AD.
Advantages:
Very good static sealing
Very good thermal expansion compensation
Greater roughness is allowed in the housing
Reduced risk of corrosion
Sealing for low and high viscosity fluids
Modern primary sealing lip with low radial forces
Protection against undesirable air contaminants.
