How to Choose the Caster Wheel (II)

Followed by the How to Choose the Caster Wheel (I). Let's continue to learn about it.

4. See load-bearing of caster wheels: For casters with same diameter, manufacturers will produce several series for different load-bearing, such as light, medium, heavy, which is to make the caster wheels and support have different thickness or materials.

To count load of single caster wheel, some insurance factor should be given. When the ground is smooth, single caster wheel load = (total equipment weight ÷ casters number) × 1.2 (insurance factor); If the ground is not smooth, then, single caster wheel load = total weight caster wheels ÷ 3. No matter what kind of uneven ground, there are at least three wheels supporting the equipment at the same time. So the insurance factor is increasing to be more reliable and resulting in greatly reduced life expectancy or cause caster wheel accident. In foreign companies, load-bearing is generally indicated by pound, while in China is mostly in kilogram. Their conversion is: 2.2 pounds = 1 kg.

5. Brakes: from the functional point of view, there are brake casters, swivel brake support, and double-brake brakes, as well as tread brake, side brake, etc.

6. The layout of caster wheels on the device: different layout will affect the cost and the effort when promote.

7. Choose the stent of caster wheels: the stent is divided into directional and swivel, always made of carbon, which can be a variety of plating, such as zinc, copper, nickel, chrome, paint, etc.
