Type LS Oil Seals

LS-type shaft seals are designed for applications that require reliable sealing with low friction, combining efficient sealing performance with an optimized design that helps reduce starting torque and shaft wear. This type of seal is ideal for high-speed applications or systems where energy efficiency and reduced frictional losses are key priorities.

The LS type is characterized by a specially profiled sealing lip, designed for reduced contact pressure, which lowers dynamic friction without compromising the ability to retain lubricants (oil or grease). Some variants include a reinforcing spring to maintain consistent pressure against the shaft, while others omit the spring to allow for smoother, lighter operation.

Certain LS models also incorporate an additional dust lip, offering extra protection against the ingress of contaminants, which increases the lifespan of both the seal and the system. These seals are available with metal outer shells, elastomer-coated exteriors, or mixed configurations, depending on the installation requirements and operating conditions.

LS seals are commonly used in electric motors, compressors, gearboxes, high-speed pumps, automatic transmissions, and industrial equipment, where low friction, durability, and efficient sealing are essential.

They are available in materials such as NBR, FKM, HNBR, and low-friction compounds, selected based on fluid type, temperature, and operating speed.
