With a sealing ring, add value to reliable products!
We support your business scene with the quality of the trusted brand, Dichtmatic, in Europe, and the advanced technological proposals from Forbo Siegling. If you have any concerns regarding oil seals, such as type selection, oil leakage, or shaft wear, please feel free to consult us.
Helpful for miniaturizing and lightweighting equipment! A device that prevents the leakage of lubricating oil and the intrusion of dust and water.
The "oil seal" is an essential sealing device for moving shaft parts, serving as a seal for liquids and gases. It prevents the leakage of lubricating oil from the bearing section and protects the bearing from the intrusion of dust, water, and other contaminants from the outside. Additionally, it ensures the precision of the bearing section and brings significant benefits by reducing the consumption of lubricating oil and the costs of repairing shaft wear, making the expenses for sealing equipment negligible. Its small form allows for easy installation and removal without requiring a large space, contributing to the miniaturization and lightweight design of equipment. 【Features】 ■ Prevents leakage of lubricating oil and the intrusion of dust, water, and other contaminants ■ Protects the bearing section ■ Reduces lubricating oil consumption and repair costs for shaft wear ■ Essential for moving shaft parts as a seal for liquids and gases ■ Also helps in the miniaturization and lightweight design of equipment *For more details, please refer to the PDF document or feel free to contact us.
40 items listed! Introducing how to choose "oil seals" in the liquid resistance table for various types of rubber!
Musashi Oil Seal Industry Co., Ltd. not only focuses on seals but also challenges itself with various industrial rubber products, producing many excellent products. In this document, we will introduce how to choose "oil seals" based on the liquid resistance table of various types of rubber. You can check the contents by category. [Contents Included] ■ Hydrochloric Acid ■ Sulfuric Acid ■ Nitric Acid ■ Chromic Acid ■ Acetic Acid, etc. *For more details, please refer to the PDF document or feel free to contact us.
An oil seal that withstands harsh environments where conventional rubber cannot be used! There are also formulations compliant with food sanitation laws.
By using FFKM material, which has already been used as a material for O-rings, we can create oil seals that not only seal fixed parts but also seal rotating shafts. These seals can be used in environments with chemical substances and temperatures exceeding 200°C. We also have formulations that comply with food sanitation laws and can withstand temperatures up to 300°C. *We have a video showing the difference in volume change when fluororubber and perfluoroelastomer oil seals are immersed in acetone! For more details, please contact us or download our catalog to view.
An oil seal with heat resistance, liquid resistance, and low wear characteristics, suitable for use under harsh conditions.
The "fluorine rubber oil seal" is an oil seal that utilizes the properties of fluorine rubber, such as heat resistance, liquid resistance, and low wear. It is suitable for use under harsh conditions, such as high atmospheric pressure, chemical plants, and high-speed rotation. Due to its adoption in a wide range of fields, we have increased the lineup of mold sizes, so please make use of it. 【Features】 ■ Effective for high temperature and high-speed rotation ■ Excellent heat resistance ■ Suitable for use under harsh conditions ■ Abundant lineup *For more details, please refer to the PDF materials or feel free to contact us.
We offer oil seals in various shapes made from a diverse range of materials.
You can consider the shapes of each manufacturer centered around the Sakura seal brand. We also handle a large number of non-standard oil seals, special sizes, and oil seals made from special materials, so please feel free to contact us.
<For those struggling with space-saving design challenges!> Maintain precision while becoming more compact. Contributes to miniaturization with an oil seal just 3mm wide.
This product is a compact oil seal that maintains the precision of the product. The dramatic reduction in the volume of the oil seal promotes the evolution of equipment design. It significantly enhances the freedom of equipment development by making effective use of space and contributes to space-saving designs. We design the dimensions of the oil seals according to our customers' requests and offer suitable size proposals. We have a proven track record of supplying to manufacturers of robots, AGVs, motors, reducers, and bearings. We also have a lineup for evaluation, so please feel free to contact us. 【Features】 ■ Precision remains the same, but more compact ■ Enables the development of various equipment ■ Promotes the evolution of equipment design ■ Significantly increases the freedom of equipment development 【A must-see for those facing the following issues!】 ■ Challenges in space-saving design ■ Need for miniaturization in equipment development ■ Cannot incorporate conventional oil seals due to their width *For more details, please refer to the PDF document or feel free to contact us.
A special seal for food use is also available in the lineup! For sealing oil, water, and for sealing dust and grease!
The oil seal is made by vulcanizing and bonding a synthetic rubber sealing lip to a metal ring, and then incorporating a spring from the back of the lip. The spring-loaded lip is used for sealing oil, water, and other substances, while the lip without a spring is used for sealing dust and grease. We also handle special seals for food use. 【Product Lineup】 ■TYPE S ■TYPE SD ■TYPE SO ■TYPE SDO ■TYPE MS *For details, please request materials or view the PDF data from the download.
Supports a variety of applications from small-diameter to large-diameter rotating shafts! A diverse lineup available.
"KLOZURE" is an oil seal that retains the lubricant of the rotating shaft and prevents foreign matter contamination. We offer a wide variety of models that cater to various applications, from small to large diameter rotating shafts. Additionally, we have the "PS-SEAL" series, which features the unique fluororesin material "Gylon" from Garlock in its seal lip. 【Features】 ■ Retains lubricant of the rotating shaft and prevents foreign matter contamination ■ Available for rotating shafts from small to large diameters ■ The "PS-SEAL" series also features the fluororesin material "Gylon" *You can download the English version of the catalog.
What is an oil seal?
An oil seal is an important component for industrial machinery and automotive parts that prevents lubricating oil from leaking out and keeps foreign substances from entering. In this article, we will explain the basics of "What is an oil seal?" including its role, mechanism, types of rubber materials used in oil seals, and the main applications of oil seals.

Energy saving through low friction of oil seals, achieving low torque across a wide range!
The "Low Torque Oil Seal" can reduce power loss due to friction resistance in oil seals. By also reducing heat generation, the burden on equipment is decreased. Our company continues to research both shape and surface property improvements, successfully reducing friction resistance significantly compared to conventional products without lowering the sealing force. Depending on the dimensions and usage conditions, there may be differences in the torque reduction rate compared to conventional products, but low torque can be achieved across a wide range. 【Features】 ■ Reduction of power loss ■ Reduction of heat generation ■ Decreased burden on equipment ■ Successful reduction of friction resistance ■ Achievement of low torque across a wide range *For more details, please refer to the PDF document or feel free to contact us.
