Use Cases of Bearings with Resin

Use Case ①Product Role
■Pressure mechanism of winding machine
Economy silicone bearing standard type
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 ②Product Role
■Assistance in transferring processed materials of Bearings with Resin
Economy silicone bearing standard type
The bearing carrying screw can be easily removed.
The polyurethane of the bearing can protect the workpiece from scratches.
Use Case ③Product Role
■Adhesive application device of Bearings with Resin
Economy silicone bearing standard type
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.

Example of Use

The urethane molded bearing is used for attachment to the drive roller for positioning. If there are special requirements such as temperature or weather resistance, silicone bearings can be selected to better suit the operation of the mechanism.
Precautions
①MISUMI makes no commitment to the bearing brand
②Silicon materials can be used in special environments such as high temperature, but the usage effect is subject to actual conditions.
③Due to the influence of product technology, there may be residual gates in the silicone area. If there are appearance requirements, please choose carefully.
