Polyurethane sun wheel
Polyurethane sun wheels are gear or wheel-shaped transmission components made of polyurethane (PU) elastomer using casting or injection molding processes. Their core advantage lies in combining the strength of metal with the elasticity of rubber, leading to widespread use in high-speed transmission, heavy-duty operations, and precision equipment.

High Abrasion Resistance
Abrasion resistance is 3-5 times that of natural rubber, significantly extending service life, especially suitable for high-speed rolling (15-20 m/s) and high-strain conditions.
Typical applications: Paper feeding rollers for carton machines, pressure rollers for slitting machines.
High Resilience and Impact Resistance
Polyurethane elastomers maintain high elasticity within a wide hardness range (Shore A10-100), with excellent tear resistance and ability to withstand frequent impact loads.
Typical applications: Shock-absorbing plates for heavy machinery, buffer wheels for large stamping equipment.
Chemical Corrosion Resistance
Oil, acid, alkali, and hydrolysis resistant, suitable for special environments such as chemical and food processing.
Typical applications: Pressure rollers for printing machines, guide wheels for food packaging machinery.
Low Noise and Vibration Damping
Stable surface friction coefficient, smooth operation, reducing equipment vibration and noise.
Typical applications: Cloth guiding rollers for textile machinery, conveyor wheels for precision electronics production lines.
High and Low Temperature Resistance
Wide operating temperature range (-20℃ to +80℃), special formulations can withstand high temperatures up to 120℃, excellent low-temperature performance (remains elastic at -35℃).
Typical applications: Drive wheels for mining machinery, automotive parts.
High Load Capacity and High Strength
Tensile strength and load-bearing capacity are higher than general-purpose rubber, impact strength and bending strength are superior to plastics.
Typical applications: Shock-absorbing springs for metallurgical equipment, supporting rollers for heavy machinery.
