Musashi oil seal with superior performance and suitable for various uses. Made in Japan (hydraulic pump oil seal)

Product Description

MUSASHI has always been producing stable, high-quality products based on its unique principle of sealing. And the oil seal is famous as their most excellent and outstanding product throughout Japan.


1. Common products

Light alloy×××


♦A TYPE oil seal it is most frequently used for rotation. It is commonly used alone when placing it on one side of the object. 

♦AC/AD Indication of the use limit peripheral speed: 12m / sec   Pressure: MAX: 0.03MPa 
outer circumference AC (metal) AD (rubber)

♦ACS1/ADS1 is used as a seal for the breakdown voltage and designed to deform the lip due to the pressure reduction.

Indication of the use limit peripheral speed: 5m / sec Pressure MAX: 0.5MPa

♦ADS2  incorporates a reinforcing ring on the back side of the AC/AD-type. It has been widely adopted when a large size seal is required (more than an outer diameter of 150 mm). Sealing performance is the same as AC, and AD-type basic model.

♦K TYPE is generally used as a grease seal, also used for auxiliary (dust seal) in combination with other A-type oil seal. In addition, if the space where you plan to seal something is limited, or in order to reduce the torque, K type is also appropriate, but can not be used for very difficult sealing. 

Indication of the use limit peripheral speed: 8m / sec pressure: 0MPa  outer periphery KD (metal) KE (rubber)

♦KDS-1/KES-1 To seal the grease from the inside, you can at the same time seal the dust from the outside. It can not be used in difficult sealing or with K type basic model.

Indication of the use limit peripheral speed: 5m / sec  pressure: 0MPa

♦S TYPE generally shaft seal with different housing in the inner surface. The outer periphery of the lip is sealed by sliding, the seal body is fitted to the shaft. Please use only if you want to deny a seal specifically designed for the axis.

Indication of the use limit circumferential speed: 6m / sec Pressure MAX: 0.03MPa 

inside diameter (fitting part) SC (metal) SD (rubber)

♦M TYPE is used for felt groove. Commonly used as grease and dust seal.

♦MUD-5/MUD-8 seal with axis are often used in the bearing unit of tillers, construction machinery working under adverse conditions of  muddy waterand sand, etc.

Indication of the use limit peripheral speed: 3m / sec  Pressure: MAX: 0.03MPa

♦U TYPE is used particularly when there is a need to eliminate dust from the outside. It has been widely used for rotation as A-type.

♦UD/UE Indication of the use limit peripheral speed: 10m / sec  Pressure: MAX: 0.03MPa 
outer periphery UD (metal) UE (rubber)
 is used as a seal with pressure resistance. It is used to prevent particules and things coming from the outside.

 indication of the use limit peripheral speed: MAX: 5m / sec  Pressure: MAX: 0.5MPa

♦UDS-3/UES-3 is used as grease in the middle of the lip, to insert the axis on rigid dust side, or to temporarily cut off the oil. Performance is the same as the U TYPE basic model.

♦UDS-4/UES-4 reduce  variations ocaused by the reciprocating motion in a sliding seal.

 indication of the use limit sliding speed: 0.3m / sec Pressure: MAX: 0.5MPa

♦UDS-4/UES-4 has the same characteristics as the UE and UES-3 type. It is especially used when there is a need to do removal easily.

2. Materials 

TYPEMaterialCharacteristics and Applications
Nitrile rubber


for Normal

Usually been widely used in the oil seal of each type, stable oil resistance, wear resistance.

Application temperature: -25 ℃ ~ + 120 ℃


for Gasoline

With superior oil resistance,wear resistance,gasoline resistance better than the normal type.

Application temperature: -25 ℃ ~ + 120 ℃

for Cold

Have excellent performance particularly in low-temperature properties.

Application temperature: -40 ℃ ~ + 100 ℃


for Food

According to Food Sanitation Law,Food Additive Standards (Ministry of Health and Welfare Notification No. 370),compatible with the materials such as rubber equipment,containers or packaging (Ministry of Health and Welfare Notification No. 85).

Application temperature: -30 ℃ ~ + 100 ℃

MZ rubber hydrogenated nitrile rubberHNBR

A synthetic rubber with heat, cold resistance, deterioration gasoline resistance, stability to various lubricating oil additives, with mechanical strength, ozone&wear resistance.

Application temperature: -40 ℃ ~ + 170 ℃

Fluorine-containing rubberFKM

Particularly with excellent acid resistance, solvent resistance,heat resistance,wide range of use.

Application temperature: -20 ℃ ~ + 220 ℃

Silicon rubberVMQ

Heat-resistant, cold resistance, especially been used in high-speed rotation point. ( can not be used such in gasoline and water vaporthe.)

Application temperature: -60 ℃ ~ + 250 ℃

Acrylic rubberACM

Oil resistance,heat resistance,  suitable for the lubricant of gear oil ortorque converter oil etc,.

Application temperature: -10 ℃ ~ + 170 ℃

Chlorosulfonated polyethylene 

Heat resistance, oil resistance, acid resistance, chemical resistance,weather resistance. Strong mechanical strength and is suitable with the lubricating oil at high aniline point.

Application temperature: -25 ℃ ~ + 130 ℃

Styrene rubberSBR

Commonly been used for animal and vegetable oil or other special oil .with good elasticity, but bad at mineral oil resistance.

Application temperature: -40 ℃ ~ + 120 ℃

Butyl rubberIIR

With superior chemical resistance, small permeability,difficult to be affected by ozone or oxygen, suitable for such packing because of the very large swelling in mineral oil.

Application temperature: -30 ℃ ~ + 130 ℃

4 Fluorinated 
ethylene resin 

Heat resistance, cold resistance, chemical resistance, can be used under conditions that  the current synthetic rubber do not work.

Application temperature: -80 ℃ ~ + 260 ℃

Standard rubber hardness is Hs = 70 ° (JIS A).
Non-standard rubber hardness will be manufactured by inquiry.

Application temperature range is the limit temperature of the rubber itself. Please use at the range lower than 20 ℃ ~ 30 ℃  .
