Use Cases of Bearings with Resin
| Use Case ① | Product Role | |
■Pressure mechanism of winding machine![]() | Polyurethane has excellent wear resistance and a relatively long service life. Polyurethane has a wide range of hardness options, so you can choose different hardness levels depending on the actual pressure required. | |
| Use Case ② | Product Role | |
■Assistance in transferring processed materials of Bearings with Resin![]() | The bearing carrying screw can be easily removed. The polyurethane of the bearing can protect the workpiece from scratches. | |
| Use Case ③ | Product Role | |
■Adhesive application device of Bearings with Resin![]() | If the adhesive contains chemical components, silicone rubber can be selected. Polyurethane, which has a relatively soft hardness, can be selected to increase the bonding surface between the roll and the workpiece. | |
Caution of Bearings with Resin
① MISUMI does not guarantee Bearings with Resin brands.
② Silicone materials can be used in special environments such as high temperatures, but the usability is based on actual use.
③ Since injection holes may remain in the silicone area due to the influence of the product process, use with caution if there are appearance requirements.
