Hardness Guide

Hardness	Example
Shore A95	Golf Ball	Hard
Shore A90	Baseball
Shore A70	Softball
Shore A50	Plastic Eraser
Shore A30	Bicycle Inner Tube	Soft

Hardness tolerance range: ±5 of the indicated value.

Material Characteristics

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

Material	Description
Urethane	Excels 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 Elastic	Excels in shock absorption and oil resistance. Inferior in heat resistance and low temperature resistance.

Comparison between Materials

The following is a comparison of the resistance of the materials:

	Weak							Strong
Mechanical Strength	Silicone	Low Elastic	Butyl	Ethylene	Nitrile	Fluorine	Chloroprene	Urethane
Weather Resistance	Nitrile	Low Elastic	Chloroprene	Urethane	Butyl	Silicone	Ethylene	Fluorine
Abrasion Resistance	Silicone	Low Elastic	Butyl	Ethylene	Chloroprene	Urethane	Nitrile	Fluorine
Heat Resistance	Low Elastic	Urethane	Nitrile	Chloroprene	Butyl	Ethylene	Silicone	Fluorine
Oil Resistance	Butyl	Ethylene	Silicone	Chloroprene	Urethane	Low Elastic	Nitrile	Fluorine

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

Use	Sideways	Over	Under	Diagonal
Use
Recommended Products	Press-fit bearing	Press-fit bearing	Lightweight: 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.
