Teach You How to Distinguish the Quality of Casters

PU Castor Wheels have high dimensional accuracy, coupled with annealing treatment, their mechanical properties, and process performance are better than hot-rolled sheet steel. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel. However, these materials have disadvantages such as poor load-bearing capacity, intolerance to acids and alkalis, high noise during rotation, damage to the ground, and intolerance to impacts. Sealing and dustproof and anti-winding.
The damping spring of the shock absorber is completely sealed and has good dust resistance, making it suitable for different options and requirements. Of course, we should follow the above series of test methods step by step during product production. This is not only to ensure the quality of the product but also to be responsible for our products. When the polyurethane caster moves or wants to control its driving direction, the force must be transmitted to the caster through the object and overcome a certain resistance. The size of the resistance depends on: load, wheel diameter, wheel material, wheel surface shape, and the place where the caster rotates. Situation etc.
Pu Castor Wheels
Load refers to the instantaneous load-bearing capacity of the caster when it is impacted or shaken by the load. Installation height: refers to the vertical distance from the ground to the installation location of the equipment, and the installation height of the caster refers to the large vertical distance from the caster base plate and the edge of the wheel. The excellent properties of polyurethane casters enable it to be used in aerospace, military, biological and other fields.
Impact test: The maneuverability of the slider movement. The user can use this feature to compile a slider movement method suitable for the processing technology, which can effectively improve the accuracy and stability of the product, improve the life of the mold and the production rate, and can achieve silence Blanking can even expand the processing scale (such as magnesium alloy stamping processing, etc.), suitable for punching, press-fitting, stretching, embossing, and tortuous processes.
Compared with the one-piece ball bearing of the same specification, it has the characteristics of heavier carrying capacity, more uniform carrying capacity, and larger static load capacity. It is suitable for industrial fields that require high carrying weight. How to distinguish the quality of polyurethane casters: The wheels can be matched with different bearings according to customer needs, and each perfect match can be applied to different products and equipment.
It is often seen at home, so what is the load-bearing performance of polyurethane casters? Cold rolled steel sheet is the abbreviation of ordinary carbon structural steel cold rolled plate, commonly known as the cold plate. It is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Since it is rolled at room temperature, no scale is produced, so the surface quality of the cold plate is good.
For conductive casters, the resistance value should not be greater than 104 ohms, while the resistance of antistatic polyurethane casters should be between 105 ohms and 107 ohms. Rolling resistance and rotation resistance measurement: impact resistance. Industrial, commercial, medical equipment and machinery, logistics and transportation, environmental cleaning products, furniture industry, beauty equipment, food machinery, hardware production, and other industries are inseparable from casters. Now casters are made of nylon, plastic, rubber, and other materials. We are PU skateboard wheels supplier, if you are interested in our products, please feel free to contact us.
