This blog will guide you through eight common uses that showcase their reliability and wide range of use.
What are Polyurethane Coated Bearings?
Definition and Composition
Polyurethane-coated bearings are carefully crafted components. They feature polyurethane coatings applied to both the rolling elements and races of the bearing. This high-performance polymer consists of a series of connected molecules that form a strong chain. The process of applying polyurethane to the bearings involves advanced techniques to make sure a uniform and robust coating.
Key Properties
The key properties of polyurethane coated bearings include:
- Durability: They offer an extended lifespan because of their resistance to wear and tear.
- Low Friction: The friction coefficient for polyurethane can range from around 0.1 to 0.3. This is significantly lower than many other materials, which leads to less heat generation and energy loss.
- Chemical Resistance: They can withstand exposure to various chemicals, making them ideal for harsh environments.
Benefits of Using Polyurethane Coated Bearings
Durability and Longevity
Polyurethane bearings offer a long-lasting and durable performance due to their robust material properties, wear resistance, and low friction. They're designed to handle high loads without bending out of shape, reducing wear by avoiding metal-to-metal contact. The material's resistance to chemicals and sealed designs protects against harsh environments and dirt, while their self-lubricating requires less maintenance, ensuring a longer service life.
Noise Reduction
Polyurethane bearings reduce noise. Through their smooth rolling action, sound-soaking properties, compatibility with machinery parts, they reduce friction and impact. They 're made to avoid metal-on-metal noise and often include noise-absorbing design features, enhancing both comfort and performance.
Chemical Resistance
Polyurethane-coated bearings are great for places that deal with harsh chemicals. They can handle corrosive substances without getting damaged, which is perfect for industries with rough conditions.
