The use range of casters is getting larger and larger. Using the correct casters can save costs and improve work efficiency. How much do you understand about casters? The editor will tell you "Cold knowledge you have to know about casters"
1. The default unit of measurement is inches.
2. Iron core wheels and cast iron wheels are more load-bearing than other wheels?
No. The technology in the process makes the injection-molded wheels have the same load-bearing capacity. Some people in the market use cast iron wheels, which is low in price and cost-saving.
3. The surface treatment of the caster bracket is generally galvanized and black painted. In the market, you usually see two colors of brackets: silver and black. Silver is electroplated and plated with a layer of zinc to change the color of the bracket to silver; black is sprayed with black oil when painting, which changes the color of the bracket to black.
4. Double bearings are more stable than single bearings, and single bearings rotate faster. Double bearings are used in high-end products, and their stability, mute effect and load-bearing capacity are stronger than single bearings. The single bearing is a simplified version of the double bearing. Although its performance is not as good as the double bearing, it is more cost-effective than other bearings. If you want to save costs, you can use a single bearing.
5. Braking method: Side brakes are commonly used abroad, and double brakes are used domestically. The design of the side brake is more user-friendly, suitable for many devices, and the price is relatively cheap; the appearance of the double brake is more beautiful, and you need to pay attention to the "installation height" during installation.
6. Iron wheels are more resistant to corrosion than other wheels? No, the single wheels produced by regular caster manufacturers are all tested by salt spray (such as wind and fire casters), which meets national standards. If you buy iron core wheels, the price is even more expensive.
7. Rubber wheels (ER wheels) are softer than polyurethane wheels (PU wheels)? Not necessarily. The hardness of the material can be adjusted. Some manufacturers have rubber wheels that are harder than nylon wheels, so rubber casters also have hard rubber and soft rubber. When you buy casters, if you don't require them, they are the default soft rubber.
