Noise Reduction: The polyurethane layer helps to dampen vibrations and reduce operational noise, making these bearings ideal for environments where noise control is important.
Wear and Impact Resistance: Polyurethane is known for its high resistance to abrasion and impact, extending the life of the bearing in demanding applications.
Corrosion Resistance: The coating protects the metal components from moisture and chemicals, reducing the risk of corrosion, especially in environments exposed to harsh conditions or where bearings come into contact with liquids.
Non-Marking: In applications where surface marking is a concern (e.g., conveyor belts, rollers), polyurethane-coated bearings prevent marks on sensitive materials.
Applications: These bearings are typically used in conveyor systems, roller systems, material handling, packaging machinery, and other equipment that requires smooth, quiet, and durable operation.
