High‑Performance Industrial Oil Seals for Rotating Shaft Applications

In industrial applications, oil seals play a crucial role in ensuring
machinery operates efficiently and reliably. They are primarily designed to
prevent the leakage of lubricants while keeping external contaminants out.
Oil seals are widely used in engines, gearboxes, hydraulic systems, and many
other mechanical systems. Different applications demand different types of
oil seals, each designed to perform under specific conditions. Below are
some of the most common types of industrial oil seals.

TC-Type Oil Seal

The TC-type oil seal is one of the most commonly used types in industrial
applications. It typically consists of a metallic casing, a rubber lip, and
a spring. The design of the TC-type oil seal allows it to be used for high-
speed rotating shafts, and it is commonly found in automotive, motorcycle,
and hydraulic systems. Its primary function is to prevent oil leakage while
also blocking external contaminants such as dust and water from entering the
system.

TG4-Type Oil Seal

The TG4-type oil seal is a more advanced version of the TG-type, specially
designed for high-pressure and high-temperature environments. Compared to
the standard TG-type, the TG4 seal incorporates special sealing materials
and structures, enabling it to provide longer-lasting performance under
extreme conditions. The TG4-type oil seal is ideal for use in hydraulic
systems, heavy machinery, and high-end automotive engines, ensuring
reliability even in the most demanding conditions.

V-Type Oil Seal

The V-type oil seal is a single-lip oil seal, typically used in less
demanding applications. Its compact design makes it suitable for low-speed
and low-pressure applications. V-type oil seals are commonly used in lighter
equipment, household appliances, and similar settings, where preventing oil
leakage and minimizing friction are the key priorities.

Single-Lip Oil Seal (SA Type)

The SA-type oil seal is a type of single-lip oil seal that is typically used
in applications requiring less stringent sealing performance. It is simpler
in structure than other oil seals, but still offers sufficient sealing
capabilities for many standard equipment needs. The SA-type oil seal is
commonly used in static sealing or low-speed machinery.

Double-Lip Oil Seal (SB Type)

The SB-type oil seal is a dual-lip design, offering enhanced sealing and
contamination resistance. The design with two sealing lips significantly
improves the sealing performance, reducing the possibility of lubricant
leakage. SB-type oil seals are commonly used in mechanical equipment,
engines, gearboxes, and other applications where a higher level of
protection is required.

Oil seals are essential components in industrial machinery, and selecting
the correct type is critical to the equipment’s performance and longevity.
Each type of oil seal is designed to handle specific operating conditions,
such as speed, temperature, and pressure. By choosing the right oil seal for
the job, you can ensure optimal equipment efficiency and extend the lifespan
of your machinery.
