introduction of each oil
- ●synthetic oil
Lubricants designed to excel in specific performance and can be selected according to the bearing application. - ●semi-synthetic oil
A sophisticated general-purpose lubricating oil with excellent heat resistance and evaporation characteristics, and less sludge generation. It can be used in a wide range. - ●mineral oil
It is a general-purpose lubricating oil. Generally, general-purpose oil has a short life cycle as a product, and it is necessary to change the design every time it is discontinued, but there is no risk of discontinuing the PML series.
PML-A～D :General grade
PML-K～M:Excellent wear resistance, especially suitable for high load applications - ●Anti-corrosion oil
A rust preventive oil developed to be most effective for sintered machine parts. - ●Oil repellent
It is effective in preventing oil leakage from sintered oil-impregnated bearings.

- ●Compatibility with resin/rubber
Depending on the type of lubricating oil, certain resins and rubber may deteriorate.
It is recommended to use the oil evaluated as 〇・△ after confirming the compatibility. Compatibility with general resins and rubber
◎:excellent 〇:good △:Confirmation is required when using - ●Flash point
When a small flame is brought close to the oil heated under the specified conditions, if the oil reaches a certain temperature or higher, the mixed gas of oil vapor and air will ignite. This temperature is the flash point. It is used as a measure of oil flammability. - ●Specific gravity
This is the ratio of the mass (weight) of a certain substance to the mass of water of the same volume, and the value at 15°C is shown.
