3. Working

The PU rollers function by transferring rotational motion from an axle or shaft to perform a variety of mechanical tasks such as conveying materials, driving systems, or performing precise movements. Their high durability and resilience make them ideal for long-term use in heavy-duty and high-load environments. The polyurethane composition provides an elastic surface that reduces noise and vibration, making them more efficient in sensitive operations.

4. Principle

The principle behind the PU roller is simple: a core (metal or plastic) is coated with polyurethane material, which offers better abrasion resistance and elasticity than traditional materials like rubber or steel. As the roller rotates, the surface interacts with the load, reducing friction and providing smooth, controlled movement. PU rollers are used for both horizontal and vertical movement systems, offering low wear-and-tear over time.

5. Assembly

The PU rollers are assembled in several steps:

1. Core Selection: Choose the appropriate metal or plastic core based on the required load capacity and application.
2. Polyurethane Coating: The core is then coated with a layer of polyurethane using a molding process that ensures the thickness and hardness meet specific customer requirements.
3. Curing Process: The rollers undergo a curing process to ensure that the polyurethane adheres properly to the core and achieves the required mechanical properties.
4. Finishing: After curing, the rollers are polished or textured as per the required specifications and are then tested for uniformity and strength.

6. Installation Process

Preparation: Clean the installation area and ensure that the roller system is free from debris and dirt.
Mounting the Roller: Insert the PU rollers into their housing, ensuring they are securely attached to the axle or shaft.
Adjustments: Depending on the application, you may need to adjust the position of the rollers to ensure correct alignment for smooth operation.
Lubrication: If necessary, apply light lubrication to the roller shafts and surrounding components to ensure easy rotation and reduce wear.
Testing: Run a short test to ensure the rollers function smoothly without unusual noise or vibration.
