Caster Wheel Materials
Caster Wheel Materials
Time of issue : 2019-05-20 17:16:00
Caster wheels involve numerous different material types, with the most common being nylon, polypropylene,1 polyurethane, rubber and cast iron. 1.Polypropylene Wheel Swivel Caster (PP Wheel) Polypropylene is thermoplastic material known for its shock resistance, corrosion resistance, friction resistance, and its non-marking, non-staining, and non-toxic performance, as well as a material that is odorless and will not absorb moisture. Polypropylene can resist many corrosive substances, with the exclusion of strong oxidizers and halogen hydrogen compounds. The applicable temperature range is between -20℃ and +60℃, though the bearing capacity will decrease in ambient temperatures of more than +30℃. 2.Nylon Wheel Swivel Caster Nylon is a thermoplastic material that is known for its corrosion and friction resistance, odorless and non-toxic structure, and its non-marking and non-staining performance. Nylon can resist numerous corrosive substances, however, it will not be resistant to chlorine hydrogen compounds or heavy metal salt solutions. Its applicable temperature range is between -45℃ and +130℃, making it applicable for short term use in high temperature environments. It should be noted however, that at ambient temperatures higher than +35℃, the bearing capacity will decrease.

1.According to the usage environment a. When choosing an appropriate wheel carrier, the first thing to take into consideration is the wheel caster’s bearing weight. For example, in supermarkets, schools, hospitals, office buildings and hotels, the floor is good, smooth and goods carted around are usually light, meaning that every caster will carry roughly 10 to 140kg. Therefore, a suitable option is a plating wheel carrier formed using a stamping process on a thin steel plate (2-4mm). This type of wheel carrier is light, flexible, and silent. b. In places such as factories and warehouses where cargo movement is more frequent and the load is heavier (280-420kg), we recommend using a wheel carrier made of a 5-6mm thick steel plate. c. If used for carrying more heavy objects such as those commonly found in textile factories, automobile factories, or machinery factories, due to the large load and long walking distance, each caster should be capable of carrying 350-1200kg, and be manufactured using an 8-12mm thick steel plate wheel carrier. The movable wheel carrier uses a plane ball bearing, and the ball bearing is mounted on the bottom plate, allowing the caster to bear the heavy load while still maintaining a flexible rotation and impact resistance. We recommend using caster wheels made of imported reinforced nylon (PA6) super polyurethane or rubber. Based on specific application needs, it can also be galvanized or sprayed with a corrosion resistance treatment, as well as given a winding prevention design. d. Special environments: cold and high temperature locations place a great deal of stress on the casters, and at extreme temperatures, we recommend the following materials · low temperatures under -45℃: polyurethane · high temperatures close to or above 230℃: special heat resistant swivel casters 2.According to the bearing capacity During the selection of the bearing capacity of the casters, users need to take into account specific safety margins. We use the most commonly used four wheel casters as an example, though choices should be made based on the following two methods: a. 3 casters bearing all weight: One of the casters should be suspended. This method is suitable for applications where the casters bear a greater momentum over poor ground conditions while moving goods or equipment, especially in larger, heavier total weight amounts. b. 4 casters bearing a total weight of 120%: This method is suitable for ground conditions that are good, and the impact on the casters is relatively small during the movement of goods or equipment. c. Calculate the carrying capacity: in order to calculate the load capacity needed by the casters, it is necessary to know the deadweight of delivery equipment, maximum load and the number of caster wheels and casters used. The load capacity required for a caster wheel or caster is calculated as follows: T= (E+Z)/M×N ---T= the loading weight required for a caster wheel or caster ---E= deadweight of delivery equipment ---Z= maximum load ---M= the number of caster wheels and casters used ---N= Safety factor (about 1.3 - 1.5). Attention should be paid to the cases where the casters will be exposed to a significant amount of impact. Not only should a caster with a large load bearing capacity be chosen, but specially designed impact protection structures should also be chosen. If a brake is needed, casters with single or double brakes should be selected. · low temperatures under -45℃: polyurethane

1. Dual brake: a brake device that can lock the steering and fix the rotation of wheels. 2. Side brake: a brake device installed on the wheel shaft sleeve or tire surface, which is controlled by foot and fix the rotation of wheels only. 3. Direction locking: a device that can lock the steering bearing or turntable by using an anti-spring bolt. It locks the movable caster into a fixed position, which turns one wheel into a multi-purpose wheel. 4. Dust ring: it is installed on the bracket turntable up and down to avoid dust getting on to the steering bearings, which maintains the lubrication and flexibility of the wheel rotation. 5. Dust cover: it is installed at the ends of the wheel or shaft sleeve to avoid dust from getting onto the caster wheels, which maintains the wheel lubrication and rotation flexibility. 6. Anti-wrapping cover: it is installed at the ends of the wheel or shaft sleeve and on the bracket fork feet to avoid other materials such as thin wires, ropes and other sundry winding in the gap between the bracket and wheels, which can keep the flexibility and free rotation of the wheels. 7. Support frame: it is installed in the bottom of the transport equipment, ensuring the equipment remains in a fixed position. 8. Other: including steering arm, lever, anti-loose pad and other parts for specific purposes.
