Urethane Molded Rollers With Bearings

Polyurethane is sintered onto the outer circumference of the core material to form a high-adhesion coated layer, creating a bearing-type roller suitable for transporting and sliding various workpieces.

The core material has no surface treatment.
Bearing material: SUJ2.
Polyurethane is ether-based polyurethane.
(dh) size is for reference only.

Feature 1: The polyurethane layer is directly sintered onto the outer circumference of the core material, making it difficult to peel off.
Feature 2: Thanks to its excellent mechanical strength and wear resistance, polyurethane is widely used to prevent scratches and cracks when transporting fragile items such as glass and acrylic.
Feature 3: Compared to metal rollers, polyurethane rollers are less likely to transmit vibrations and noise.
Feature 4: Polyurethane has low dust generation.
Feature 5: Using ether-based polyurethane, it maintains high mechanical strength and wear resistance, while offering better hydrolysis resistance and lower environmental requirements compared to ester-based polyurethane.

■ Characteristics Table

(1) The economical polyurethane roller uses ether-based polyurethane, which is resistant to hydrolysis and has lower environmental requirements. However, since the bearing position is made of SUJ2 material, rust prevention is still necessary.
(2) Please refer to the actual product for material color.
(3) The (dh) dimension is for reference only, as the core material is extruded tubing and is not machined. For reference dimensions only.
(4) For dimensions on the drawing without specified tolerances, general tolerances (medium grade) are applied.
