What are the characteristics of casters of different materials and how to select them
Caster is a kind of non-driven, using a single wheel or more than two wheels through the design of the framework together, used to install in a larger object below, so that the object can be easily moved. According to the style can be divided into directional casters, universal casters; according to the brake or not, can be divided into braked casters and brakeless casters; according to the use of classification can be divided into industrial casters, furniture casters, medical casters, scaffolding casters, according to the wheel surface material, there are nylon casters, polyurethane wheels, rubber casters, etc.
Let's see what features these different materials have for casters!
Caster material
1. Nylon casters have the largest load, but also the largest noise, wear resistance is fair, suitable for the use of noise and high load requirements of the environment, the disadvantage is that the floor protection effect is not good.
2. Polyurethane casters are moderately soft and hard, with the effect of silence and protection of the floor, wear resistance is also better, sewage resistance and other characteristics are also excellent, so they are mostly used in environmental protection, dust-free industry. Polyurethane friction coefficient of the ground is relatively small, suitable for the use of the widest environment.
3. Rubber casters as a more frequently used, due to the special material of rubber, its own elasticity, good anti-slip, and the ground friction coefficient higher characteristics, so in the transport of goods can be stable, safe movement, so in indoor and outdoor has a wide range of use. Rubber casters rubber wheel surface can well protect the ground, while the wheel surface can absorb the impact caused by the object in moving, quiet, relatively economical, widely used in a variety of occasions, generally high requirements for environmental tidiness is suitable for the choice of artificial rubber material casters.
Generally speaking, soft ground is suitable for hard wheels, and hard ground is suitable for soft wheels. Such as rough cement tarmac surface is not suitable for nylon casters, but should be selected rubber-type material. You can choose the right caster for you according to this feature.
