There are a variety of casters available on the market, ranging from large to small wheel diameters and high to low prices. In fact, in addition to the quality difference, there’s a key functional difference for casters. The functional difference can be used in the corresponding products to give full play to the casters. Therefore, as long as you understand your own products and understand your demands, you can select the most suitable casters from the full range of choices on the market.
The consideration while selecting casters can be broadly categorized as follows:
| Industrial Casters |
| Load Capacity
Each castor will indicate the maximum load, which is the maximum weight a single caster can carry on a flat ground. After knowing the weight of the application device and calculating the total load capacity of the four casters, we will be able to select the suitable casters accordingly.
| Wheel diameter
The size of the wheel diameter is positively related to the load capacity. If the demand for load capacity is not too high, small wheels can be applied. Larger wheel diameters perform better shock resistance on uneven ground.
| Wheel material
Depending on the use environment, considering whether oil resistance, hydrolysis resistance, hardness and operating temperature, etc., consumers can choose different materials of wheels.
Generally the fitting has the types of thread stem, top plate, fixed, round stem and bolt hole. The fitting is also related to the load capacity and it can be selected according to the request of load capacity and the specifications of the equipment.
| Medical casters |
The consideration for medical casters is the same as industrial casters. In addition to the four points above, medical casters have higher stability requirements for medical staff and patients. The following can be considered additionally
| Smoothness upon slide and turn
Swivel head and wheel center is sealed with precision ball bearings, which can effectively improve the turn smoothness and increase the stability.
| Housing material
When it comes to select the housing of caster, in additional to load capacity, the use environment should be also considered. If it is for better appearance which is for hospital use, the plastic housing or rust-resistant material is recommended, e.g. Aluminum alloys housing from TKS Casters.
| Pass hospital bed safe standard or not
Selecting the castors that are certified with DIN EN12531 will ensure the use safety and effectively reduce the risk of accidents. TKS CASTERS even provides professional services to customers. We are able to test the caster-related items in the bed safety standard IEC60601-2 for the hospital bed customers. With certification, the use safety is much ensured.
