Material Characteristics

It is important to select the right material according to your application, the different materials we handle within the catalog are

MaterialDescription
UrethaneExcels in mechanical strength. Weak in heat and chemical resistance. Wide range of hardness variations.
Nitrile (NBR)Excels in abrasion resistance and oil resistance, and economical. Inferior in weather resistance. Avoid using in areas where it may be exposed to direct sunlight or around ozone-generating electrical devices.
Chloroprene (CR)Well-balanced in properties and economical.
Ethylene (EPDM)Excels in weather resistance and economical. Inferior in oil resistance and fire resistance.
Butyl (IIR)Excels in weather resistance and airtightness. Suited for inner tube of air tire. Inferior in oil resistance and fire resistance.
Fluorine (FPM)Excels in most properties.
Silicone (SI)Excels in heat resistance. Inferior in mechanical strength.
Low ElasticExcels in shock absorption and oil resistance. Inferior in heat resistance and low temperature resistance.

Precautions

Urethane will change color and turn yellow over time.

Particularly antistatic urethane (gray color) may undergo noticeable discoloration, but, without physical problems and maintaining its properties.

The process of discoloration over time is shown below. Please consider this before use.

*Time and level of discoloration varies greatly depending on the environment of use, etc.

Before Changing After Changing

Way to Use

UseSidewaysOverUnderDiagonal
Recommended ProductsPress-fit bearingPress-fit bearingLightweight: Press-fit bearings
Heavyweight: Molded bearings
Molded bearing

[!] The bearing urethane might come loose even if the bearing is used upward, sideways or downward, the bearing urethane can come loose. It happened because an unbalanced load is applied due to mounting accuracy, balancing of the workpiece, or it is used at high rotational speeds.

Way to Use

Rotation Positioning Mechanism

This mechanism allows to temporarily fix the rotation position to inspect the surface finish of the inside of the workpiece.

Molded bearing (UMBGH15-40) of Shore A70, a urethane with a high coefficient of friction, is used for temporary fixation
