Product material: Our products are made from high-quality materials with good aging resistance, thermal conductivity, oil resistance, and chemical resistance. Enhanced wear resistance provides increased strength and flexibility, ensuring no cracks or tears for extended service life. The inner ring features a serration design that ensures high stability and prevents belt turnover on the wheel. A center groove allows heat dissipation, making it suitable for high-speed transmission. Ensures smooth movement on the pulley, reduces vibration, and operates with low noise.
