The shaft end and inner diameter may sometimes not be surface treated.
Urethane is sintered on the outer perimeter of the core material.
Since the core material is drawn material, the inner diameter d1 may be uneven.

Polyurethane sintered products do not have dimensions marked with an *.
Some sizes may not be available in all specifications. Please note.
Material color is subject to the actual product. Polyurethane will yellow over time, but its properties will not change.
Tolerance measurement environment: Temperature 23±2°C, humidity 40–80%.

The bearings used in this product are not guaranteed to be of a specific brand.
 
Product Features
 
Feature 1: The core material uses drawn profiles, achieving weight reduction while better controlling the cost.
Feature 2: Sintered urethane products, based on their excellent mechanical strength, are widely used to prevent the scars and cracks that occur when brittle objects such as glass and acrylic are transported.
Feature 3: Polyurethane is sintered onto the surface of the core material, providing higher polyurethane adhesion compared to press-fit or adhesive products, making it more suitable for applications with larger axial loads.
Feature 3: Urethane sintered products are less likely to transmit vibration and sound.
Feature 4: Polyurethane has low dust generation, and since it does not contain carbon, it is a material that is not prone to color transfer. (*Natural color only)
Feature 5: Multiple hardness options available for different usage scenarios.

Precautions
 
(1) As this is a core material product and is a drawn profile, the d1 inner diameter may be uneven.
(2) The shaft end and inner diameter are not surface treated.
(3) 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.

(4) 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.
 
(5) State changes of the product after hydrolysis
  · Polyurethane surface becomes sticky
  · Irreversible marks are left when pressed lightly with a fingernail
  · Polyurethane hardness decreases
  · Polyurethane dries and cracks, easily disintegrates into powder

(6) 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
 
Detailed example of MISUMI urethane pipe roller inspection mechanism
Organization Name: Gasket Bubble Extrusion Fixture

Function of the mechanism:
Clamp the fitted gasket with a rubber roller to remove air bubbles.

Role of urethane tubing:
Use polyurethane tubing rollers to clamp and rotate the workpiece (attach the gasket). Because the surface is sintered with polyurethane, it can leave marks on the workpiece surface while enabling displacement of the workpiece and removal of bubbles by extrusion.
