Polyurethane Roller With Bearing, Thickness Configurable

Urethane is sintered onto the outer circumference of the core material to form a high strength urethane molded roller. A roller suitable for the transportation and sliding of various workpieces.

Feature 1: The polyurethane layer is directly sintered onto the outer circumference of the core material, making it resistant to fall-off.
Feature 2: Based on its excellent mechanical strength, it is widely used to prevent scratches and cracks from occurring during the tight transportation of brittle items such as glass and acrylic.
Feature 3: Urethane does not easily transmit vibration or sound.
Feature 4: Urethane has a low dust emission property. In addition, since it does not contain carbon, it is a material that is not likely to cause color transfer. (*Natural color only)

Due to previous omissions in the translation of the hardness unit Shore A, the term 'Shore hardness' has now been officially corrected to 'Shore hardness.' Updates to electronic and printed catalogs may be delayed, so please refer to the website for the most accurate information.
Please refer to the actual product for material color. Urethane may yellow over time, but its characteristics will not change.
Tolerance measurement environment: temperature 23+/-2℃, humidity 40 to 80%.
Urethane is sintered on the outer periphery of the core material.

Natural color

Urethane has a discolored characteristic; the above colors are for reference only.

(1) The polyurethane bonded to the bearing may become detached under harsh operating conditions. If higher polyurethane adhesion is required, please select the sintered polyurethane roller.
(2) Please refer to the actual product for material color. Polyurethane will yellow over time, but its properties will not change.
(3) Regarding the discoloration of urethane
  Urethane may darken in color by absorbing ultraviolet rays or light, a phenomenon known as yellowing. However, this does not affect its physical property. Please understand this when using the product.

(4) Urethane hydrolysis characteristics
If urethane is used for an extended period in environments containing moisture or humidity, hydrolysis will occur and cause deterioration.
In regions with high humidity, it is recommended to manage the temperature and humidity of the warehouse and operating environment to extend the product's service life.
 (6) Urethane dimension change
The dimensions of urethane will change with the surrounding temperature, but the amount of change is small, and it will return to its original size after being left at room temperature for several hours.
