Precautions

①Material color is subject to the actual product. Urethane (white) may be yellowed due to aging.
②MISUMI does not guarantee the bearing brand.
(3) For anti-rust performance and maintenance of metal materials and surface treatment, please click

here.

(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) Changes in Product Condition After Hydrolysis
· Polyurethane surface becomes sticky
· Irreversible marks appear when pressed lightly with a fingernail
· Polyurethane hardness decreases
· Polyurethane dries and cracks, easily disintegrates 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.

Example of Use

Example of Use①	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 Use②	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 Use③	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.
