This great invention facilitates us a great deal and becomes widely used by people from all walks of life. So, here we are to help you find the best swivel caster. Read on to learn more.
Above all, you need to understand the basic types of casters before making a purchase. Swivel casters can be classified by functions, and there are mainly four types available on the market: supermarket swivel casters, and furniture casters, medical casters, industrial casters,
Supermarket Swivel Caster
This kind of swivel caster is ideal for the supermarket shelf movement. It is light and not easy to scratch the ceramic floor tiles. Also, it contributes to the flexibility of the shopping cart.
Furniture swivel caster
This kind of swivel caster with high bearing capacity is specially designed for furniture with a low center of gravity furniture. Attaching to the leg of a piece of furniture, they allow it to roll on carpets and hard surface floors.
Medical Swivel Caster
Medical swivel casters perfectly meet the requirements of medical operations. It is light, flexible, soft, noiseless, wear-resistant, and chemical resistant.
Industrial Swivel Castor
These swivel wheels are made of iron-core rubber, plastic-core polyurethane, reinforced nylon, or PVC, etc. They perfectly work with mechanical equipment in factories. Also, they have the excellent bearing capacity, high wear resistance, and good impact resistance.
There are swivel casters for other purposes, and you should choose the one according to your needs. Below are four essential tips to help you make a conscious and informed purchase.
1. Suitable Materials
• Rubber casters: cannot come in contact with acids, grease, or chemicals.
• TPR casters: commonly used in hotels, hospitals, wood floors, ceramic tiles, and other floors that require low noise.
• Nylon caster: suitable for uneven ground or ground with iron chips and other substances.
• Polyurethane casters: a practical compromise offering moderate floor protection with more excellent load capacity.
2. Load Capacity
Exceeding rated capacity can lead to caster failure in the field. Below is how we calculate the load capacity of swivel casters:
T = (E + Z) / m * n
T = Each wheel’s loading capacity;
E = Equipment’s self weight;
Z = Equipment’s max load;
M = Quantity of the wheel;
N = safety factor (usually 1.3-1.5)
3. Appropriate Diameter of Swivel Caster
The diameter of swivel caster wheels depends on the load capacity and the driving force to the carrier when it is loaded. Generally, the larger is the wheel diameter, the higher is the bearing capacity, and the easier it is to push the cart. Meanwhile, these swivel wheels can largely protect the ground from damage.
4. Flexible Wheels
It is a rule of thumb that larger wheels require less effort. Also, the roller bearings have a higher load capacity compared to the same size of ball bearings. The installation of high-quality roller bearings makes single wheel rotation more flexible, quiet and has a higher carrying capacity. A top pick for heavier and industrial uses.
Here are other factors to be considered when you gear up to buy swivel casters, such as space of the field, obstacles or substances on the ground, environmental conditions, and so on.
