Most short-distance transportation equipment in industrial applications use casters because they need less force. Besides, casters are cheaper than tires. The castors are classified according to various standards, such as bearing capacity, materials used, design, application, temperature, and shock absorption capacity. Bearing capacity is the primary method of caster classification. For instance, SUPO heavy duty casters are designed to carry the heavy load. However, even the capacity will vary depending on the material and size used in the caster. Now I am going to walk you through what to consider when choosing heavy duty casters.
We can further divide heavy casters from SUPO into three groups. They are medium heavy, heavy, and ultra heavy, which depends on the capacity of the caster. The largest bearing capacity of ultra heavy casters can reach 4000 kg. For many material handling applications, a caster with a low center of gravity is required to prevent tipping. As a result, SUPO also offers heavy and ultra-heavy low center casters to meet the needs of equipment manufacturers.
The SUPO Caster is offered in three different kinds of materials like nylon, high-temperature nylon, plastic core nylon, polyurethane (PU), core polyurethane, aluminum core polyurethane, polypropylene, elastic and foam rubber, etc. You could select according to the surface it uses. Most casters are suitable for surfaces that most equipment will move, such as carpets, linoleum, wood flooring, concrete, and many other types. But, foam rubber casters cannot be used on reinforcing bars because they will be damaged.
When selecting a specific caster for an application, it is recommended to consider controlling its surface type and operating conditions. It then assigns the load to be carried to the selected caster. Each SUPO caster has a part number, and for each part number, the bearing capacity (kg) is precisely positioned together with other dimensions. In general, the wheel diameter is proportional to the carrying capacity, and in most cases, the kingpin wheel which can carry a giant load features a larger diameter. Most heavy duty casters with large capacity are made of polyamide.
There is a plate with holes on the top of the casting machine, and the equipment holes should be compatible for easy installation. For casters with higher bearing capacity, it features high loading weight. Besides, most casters have double bearings, but there are also some with four bearings.
Since it is essential to ensure that the caster is compatible with the attached equipment, the buyer shall also check the other dimensions of the caster. Tread width is the thickness of the kingpin caster, while load weight is the weight of the kingpin caster. Also, the radius of gyration is the radius of caster gyration.
You should also consider the specific operating conditions. Most commonly used casters are designed to withstand water, steam, and chemicals. However, high elastic rubber, foam rubber, and pneumatic casters are not suitable for oil and waste. Their performance will decline significantly. No caster other than high-temperature Nylon Caster shall be used in high-temperature conditions. Modified nylon, polypropylene, high-temperature nylon, and the pneumatic caster cannot be used at low temperature. For shock absorption, rubber casters and pneumatic casters are the most suitable.
Founded in 2004, SUPO is a famous castor manufacturer that has always been committed to the castor industry. It has extensive testing facilities to ensure the highest quality casters, and the brake performance of casters is also monitored. After years of development, the SUPO store has been deeply involved in many cities. In the global market, SUPO has enjoyed popularity in more than ten countries, which has become a symbol of high-quality casters’ quality. Thus, if you are looking for heavy duty castors online, don’t forget to check out SUPO.
