Polyurethane coated bearings

Product name: Polyurethane coated bearings

Sintering polyurethane or silicone on the bearing to form a rubberized bearing with high bonding strength.

Polyurethane and silicone materials with corresponding hardness can be selected according to requirements.

Features

Feature 1: The outer diameter is finished by the arc surface, which can reduce the contact point with the workpiece.

Feature 2: Each model has an allowable load for reference, making the selection more convenient. Polyurethane Formed Bearing

Feature 3: Polyurethane is partially sintered on the bearing, it is not easy to fall off, and it is suitable for various contact methods.

Precautions

① Please refer to the actual material for the color of the material. Polyurethane (white) may turn yellow due to age.

②For the anti-rust performance and maintenance of metal materials and their surface treatment, please click here.

③About the discoloration of polyurethane

Polyurethane will darken its color by absorbing ultraviolet rays or illuminating light. This phenomenon is called yellowing. But it does not affect its physical properties, please fully understand when using it.

④Polyurethane hydrolysis characteristics

If polyurethane is used for a long time in a humid or humid environment, it will be hydrolyzed and deteriorated.

It is recommended to manage the temperature and humidity of the warehouse and use environment in areas with high humidity to extend the service life of the product.

⑤The state change of the product after hydrolysis

·Polyurethane surface becomes sticky

·Tap on your nails will leave irreversible scars

·Polyurethane hardness decreased

·Polyurethane is dry and cracked, easily disintegrated into powder

⑥Dimensional changes of polyurethane

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