Is there a big difference in hardness and wear resistance between economy series urethane bearings and existing products from MISUMI?

The economy series urethane bearing is directly formed with thermoplastic materials, with good hardness stability, small deviation and almost the same level of wear resistance as existing products.

Can urethane be wiped with alcohol?

Yes, only a small amount of alcohol can be applied for wiping. Urethane is a chemical resistant material, susceptible to corrosion. It can be dried or placed naturally after applying a small amount of alcohol. Other highly corrosive chemicals can not be applied even in small amounts.

With the rise of the hardness of urethane, does the friction rise?

No, urethane is an elastomer, and the lower the hardness, the higher the friction.

Product Overview of Bearings with Resin

Bearings with Resin is used to mold the bearing, which ensures the strength of the connection, while achieving higher economic efficiency.

Product Feature of Bearings with Resin

Feature 1 : Bearings with Resin, Urethane part is made of imported thermoplastic material, with excellent abrasion resistance, and higher economy.
Feature 2 : Bearings with Resin, Bearing end cap is made of resin, which is less sensitive to the environment.
Feature 3 : Bearings with Resin, Urethane is partly formed on bearing, which is not easy to fall off, and it is suitable for various contact methods.

MiSUMi urethane bearing is also a urethane rubber coated bearing

Example Use of Bearings with Resin

Example of Use ①		Role of Product
■ Wire crimping mechanism of winding machine		Urethane has excellent abrasion resistance and long service life Urethane is available in a wide variety of hardness, and different hardness can be selected according to the actual press-fit force required.
Example of Use ②		Role of Product
■ Workpiece transfer assistance		The bearing carries male threads and is easy to disassemble. The bearing has urethane to protect the workpiece from scratches.
Example of Use ③		Role of Product
■ Gluing mechanism		When the adhesive contains chemical properties, silicone rubber can be selected. Softer urethane can be selected to increase the adhesion surface between the roll paper and the workpiece.

Precautions of Bearings with Resin

1. Material color is subject to the actual product. Urethane (white) may be yellowed due to aging.
2. MISUMI does not guarantee the bearing brand.
3. Anti-rust performance and maintenance of metal materials and surface treatment.
4. About urethane discoloring
Urethane will darken its color by absorbing UV rays or illuminating light. This phenomenon is called yellowing. But it does not affect its physical properties, please fully understand when using it.

New urethane	Yellowed urethane

5. Hydrolysis characteristics of urethane
If urethane is used for a long time in a moist or humid environment, it will be hydrolyzed and deteriorated.
It is recommended to manage the temperature and humidity of the warehouse and operating environment in areas with high humidity to extend the service life of the product.

6. State change of the product after hydrolysis
·The urethane surface becomes sticky
·Tapping with your nails will leave irreversible scars
·Decreased urethane hardness
·Urethane is dry and cracked, easily disintegrated into powder

Hydrolyzed urethane

7. Urethane dimension change
Urethane dimension will change with the surrounding temperature, but the amount of change is not large, and it can be restored to its original dimension after a few hours at room temperature.
