Introduction
Oil seals and bushes are small but critical components used inside air compressors and other industrial machinery. Even though these components are relatively simple in appearance, the correct oil seal size, shaft diameter, housing diameter, thickness, bush dimensions and material quality are essential for reliable compressor operation.
Common requirements such as:
Oil Seal 75×60×8
Oil Seal 72×50×10
Oil Seal 80×60×10
Bush 50×42×43
need to be matched correctly with the compressor's shaft, housing and application before replacement.
MK Compressor supplies a wide range of air compressor spare parts, oil seals, bushes, filters, radiators and other compressor components for different compressor brands and models. Customers can contact MK Compressor for availability of the required size and suitable replacement component.
Oil Seal Sizes Available at MK Compressor
The oil seals shown in the reference include three different dimensional specifications.
1. Oil Seal – 75×60×8
The 75×60×8 oil seal represents three basic dimensions:
75 mm – outer diameter
60 mm – inner diameter
8 mm – seal width/thickness
This type of oil seal is used where a rotating shaft requires protection against oil leakage and contamination.
Before purchasing a replacement, the dimensions should be checked against the original compressor seal.
2. Oil Seal – 72×50×10
The 72×50×10 oil seal has:
72 mm outer diameter
50 mm inner diameter
10 mm width
This specification is particularly important because even a small dimensional difference can result in an improper fit.
A seal with an incorrect inner diameter may fail to properly seal the rotating shaft, while an incorrect outer diameter may not seat correctly inside the housing.
3. Oil Seal – 80×60×10
The 80×60×10 oil seal consists of:
80 mm outer diameter
60 mm inner diameter
10 mm width
This is another commonly specified industrial oil seal dimension that may be required for compressor and machinery applications.
However, the dimension alone should not always be treated as sufficient identification. Seal profile, material, lip design, temperature compatibility and application should also be considered.
Bush Size – 50×42×43
The image also shows a Bush 50×42×43.
The dimensional specification can generally be interpreted as:
50 mm – outside diameter
42 mm – inside diameter
43 mm – length
Bushes are used in mechanical assemblies to provide a bearing/support surface between moving or mating components.
The correct bush should be selected according to:
Shaft diameter
Housing/bore diameter
Bush length
Operating load
Rotation or movement
Lubrication conditions
Operating temperature
Material requirements
A bush that is incorrectly sized can cause excessive clearance, friction, vibration and premature component wear.
Why Correct Oil Seal Size Matters in an Air Compressor
An oil seal is not simply a rubber ring. Its job is to maintain sealing around a rotating or moving shaft while helping prevent lubricant from escaping.
An incorrectly selected seal can lead to:
Oil Leakage
If the seal does not properly contact the shaft or housing, lubricant can leak from the assembly.
Contamination
A damaged or incorrectly fitted seal can allow dust, moisture and other contaminants to enter the mechanism.
Shaft Wear
Incorrect seal selection or excessive lip pressure can contribute to premature shaft wear.
Increased Maintenance
Repeated leakage means more frequent inspection, replacement and maintenance.
Compressor Downtime
For industrial compressors, even a relatively inexpensive spare part can cause expensive downtime if it fails.
That is why the correct oil seal dimensions and application compatibility should be verified before ordering.
How to Read an Oil Seal Size
A three-number specification such as:
75×60×8
is generally written as:
Outer Diameter × Inner Diameter × Width
Therefore:
75×60×8 = 75 mm OD × 60 mm ID × 8 mm width
Similarly:
72×50×10 = 72 mm OD × 50 mm ID × 10 mm width
and
80×60×10 = 80 mm OD × 60 mm ID × 10 mm width
For a bush:
50×42×43
is generally:
Outer Diameter × Inner Diameter × Length
So:
50×42×43 = 50 mm OD × 42 mm ID × 43 mm length
Important: Always compare these measurements with the original component and compressor assembly. Dimensions alone do not guarantee interchangeability.
Oil Seal Replacement for Air Compressors
When replacing an air compressor oil seal, simply searching for “same-looking oil seal” is a weak approach.
The replacement should be checked for:
Inner diameter
Outer diameter
Width
Seal profile
Shaft condition
Housing condition
Material
Temperature resistance
Lubricant compatibility
Operating speed
Application
If the original seal is available, measuring it using a suitable measuring instrument can help identify the required size.
For a compressor spare-parts supplier, providing the compressor brand, model, old seal dimensions and photographs can make identification much easier.
Air Compressor Bush Replacement
Bushes can wear over time because of:
Continuous operation
Friction
Excessive load
Poor lubrication
Misalignment
Contamination
Incorrect clearance
Common symptoms of bush wear may include:
Excessive play
Abnormal noise
Vibration
Uneven wear
Increased friction
Mechanical movement
Reduced component life
Replacing the bush with the correct dimensions is therefore important for maintaining proper mechanical fit.

For example, the manufacturer of your compressor.
2. Compressor model
The exact model number is much more useful than simply saying “air compressor.”
3. Original part photograph
A clear photograph of the old component can help with identification.
4. Dimensions
For an oil seal:
OD × ID × Width
For a bush:
OD × ID × Length
5. Original part number
If a genuine part number is printed on the old component, provide that as well.
This information allows the required spare part to be identified more accurately.
