[Feature]
● Outer diameter (D) Minimum/Maximum (mm.) : 12 and 40
● Inner diameter (d) Minimum/Maximum (mm.) : 3 and 15
● Material
- Resin : Green Thermoplastic Ester Urethane
- Bearing : Bearing Steel
[Application]
Bearings with resin are commonly used in industrial machinery.
Product Overview of Bearings with Resin
Product Feature of Bearings with Resin
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.

Dimensional Drawing of Bearings with Resin


Depending on the model, the edge of the coated layer may have radian

Material color is subject to the actual product.
Urethane is sintered on the outer perimeter of bearing.
Customized bearings are used. Please refer to the dimensional drawing for specific accuracy.
Nobrand is guaranteed for the bearings used in this product.Example Use of Bearings with Resin
| Example of Use ① | Role of Product | |
■ Wire crimping mechanism of winding machine![]() | Bearings with Resin has excellent abrasion resistance and long service life Bearings with Resin 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
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.

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.
·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

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.
