5" X 1-1/4" Yellow Polyurethane Wheel

Yantai Zhengyuan Polyurethane Co., Ltd. was established in 2007. Since its establishment, the company has been committed to the research and development, production, and sales of polyurethane products. The products produced mainly include polyurethane wheels, polyurethane sieves, polyurethane boards, polyurethane gas pipes, polyurethane pipeline cleaners, and other products. Mainly used in industries such as automotive, logistics, mining, coal mining, petroleum, and pneumatic. After nearly 20 years of development, we have a strong technical team, production team, and sales team, with multiple advanced modern production equipment. We are also located in Yantai, Shandong, the birthplace of polyurethane products in China, and have unique advantages in technological innovation and obtaining technical support. Our 5 "x 1-1/4" Yellow Polyurethane Wheel has received unanimous praise from customers for its high quality and reasonable price. You are welcome to visit the factory at any time.

1.What should be noted during the production process of the 5 "x 1-1/4" Yellow Polyurethane Wheel?
1) It is recommended to control the wheel surface hardness at a Shore hardness of 90A-95A to balance load-bearing capacity and elasticity
2) Strictly control the curing (vulcanization) time of polyurethane to avoid delamination, cracking, or delamination caused by insufficient curing
3) Surface treatment of wheel core (such as sandblasting, adhesive coating) to ensure the bonding strength between metal and polyurethane, and prevent detachment under load
4) Requires load durability testing (such as dynamic cyclic loading), high and low temperature alternating testing, and eccentric wear testing
2. Normal service life and influencing factors

3. Consequences of Improper Use of 5 "x 1-1/4" Yellow Polyurethane Wheel
1) Overloading can cause wheel crushing and bracket deformation
2) High speed over bumps or sudden braking may cause the polyurethane layer to peel off and the bearings to get stuck
3) Corrosive environment can cause polyurethane hydrolysis expansion and hardness decrease
4) Low or high temperatures can cause materials to become brittle or soften, accelerating aging
5) Installation tilt or insufficient fastening can cause uneven wear and abnormal noise
6) Long term exposure to sunlight or damp storage can accelerate yellowing and reduce physical properties
