Lubricant Retention
Help control oil or grease leakage around rotating shafts and maintain lubrication around critical components.
Oil Seals
Oil Seals are typically installed adjacent to a bearing, sealing in or sealing out, as necessary, the various liquids, gases, or solids encountered by the particular mechanism. Some Oil Seals are split for easy installation. Split Oil Seals help to reduce downtime by not dismantling machinery. Split Oil Seals are recommended for horizontal shafts. Oil Seals typically have a single lip or a double lip. Oil Seals are generally the least expensive component, but they serve to be the most important because they protect the more expensive components such as the bearings and gears.
Regularly checking and replacing Oil Seals are a part of successful preventative maintenance.

Find the right oil seal for your industrial application with EPM.
Explore key product considerations, understand your sealing
requirements, and identify the specifications needed for
your equipment.
Oil seals, also known as radial shaft seals, help retain
lubricants and protect internal components from external
contamination. They are important components in rotating
equipment where lubrication control and effective sealing
are essential.
EPM oil seal selection starts with understanding the
requirements of your application. Shaft and housing
dimensions, operating speed, temperature, lubricant type,
and material compatibility all play a role in identifying
an appropriate sealing solution.
An oil seal creates a sealing interface around a shaft or
moving component. It helps keep lubricants inside an assembly
while restricting contaminants from entering. Selecting the
right EPM oil seal begins with the mechanical and environmental
demands of the application.
The right oil seal can help support equipment protection,
lubrication control, and dependable operation. When evaluating
an EPM oil seal for your application, consider these key
sealing functions.
Help limit the entry of dust, dirt, moisture, and other
contaminants that can affect internal mechanical assemblies.
Evaluate dimensions, sealing material, shaft conditions,
and operating environment to help identify a suitable seal.
Choosing an oil seal involves more than matching its
appearance. The seal must fit the equipment and suit
the operating environment. Gather the following information
before identifying a replacement or specifying a seal
for a new application.
Need help identifying the right specifications? Contact EPM
with your available dimensions, part information, and
application details to discuss your sealing requirements.
Oil seals are used in many industrial systems that depend on
rotating shafts, lubricant retention, and contamination control.
The suitability of a particular seal depends on the equipment
design and its operating requirements.
Sealing applications in production machinery and industrial
equipment where lubricant retention and contamination
control are important.
Compatible rotating-shaft applications that require
effective sealing to help retain lubricants and protect
internal components.
Sealing applications around rotating shafts in compatible
gearboxes, drives, and power transmission assemblies.
Oil seal applications in compatible motor assemblies
and other rotating industrial equipment.
Industrial systems where equipment design, lubricant
compatibility, and operating conditions guide
product selection.
Replacement oil seals for industrial equipment, selected
using existing part numbers, dimensions, and
application requirements.
An oil seal, also known as a radial shaft seal, helps
retain lubricants and restrict contaminants around a
shaft or moving component. The appropriate design
depends on the application and operating conditions.
Start with the shaft diameter, housing bore, seal width,
operating temperature, shaft speed, and lubricant.
An existing part number can also help identify a suitable
replacement. Contact EPM if you need help determining
which details are relevant to your application.
Provide any available dimensions, the existing seal's
part number, equipment details, lubricant type, and
operating conditions. Even partial information can
be a useful starting point for discussing your requirements.
Visible leakage, cracking, hardening, deformation, or
wear around the sealing lip can indicate that inspection
or replacement is needed. Check the shaft and housing
for wear or damage as well.
No. Oil seals vary by dimensions, material, construction,
and operating capabilities. Confirm that any selected
replacement meets the requirements of the equipment.
Contact EPM with your application details, dimensions,
and any existing part references. This information helps
establish what type of sealing solution may be appropriate.
Find a sealing solution that matches your industrial
equipment and application requirements. Contact EPM to
discuss dimensions, operating conditions, and your
replacement or project needs.
