Frequently Asked Questions
Polyurethane offers significantly higher wear resistance (3-5 times that of rubber), superior oil and chemical resistance, and higher load-bearing capacity, resulting in lower long-term operational costs.
Yes, our polyurethane elastomer supports a wide hardness range from Shore A10 to D80, allowing us to tailor the pulley to your specific friction and impact needs.
Polyurethane is a strong polar polymer, meaning it has very little affinity with non-polar mineral oils and is virtually immune to corrosion from fuel and mechanical oils.
Absolutely. The material is engineered for good low-temperature performance, maintaining its resilience and preventing brittleness in cold environments.
Yes, the high coefficient of friction and elasticity of the polyurethane surface increase the grip between the pulley and the belt, significantly reducing slippage.
The Akron Abrasion value for the HJ-3190A model is ≤0.08 cm³/1.16km, ensuring exceptional longevity under heavy-duty conveyor applications.
