Caster Wheel With Zinc-plating Bracket Red PU Material Up to 350kgs

Refrigerator casters are an important part of moving the freezer. The quality of the freezer casters directly affects the movement effect of the freezer in real life. So when choosing the freezer casters, what aspects can you consider? Wanda Casters believes that everyone can choose from the following seven points.

1. Wheel material: This is very important, generally PU, TPR, PP, rubber, nylon, etc., as for the applicable temperature, surface hardness, air environment, etc.

2. Choose size: The larger the diameter of ordinary freezer casters, the less effort it will be to advance, and the better the ability to overcome obstacles. Since the beginning of the industrialization of freezer casters in the West at the end of the 19th century, the size of freezer casters is generally expressed in inches, such as China Most of the supermarket trolleys use 5-inch and 4-inch freezer casters. At present, the popular freezer casters in the market have sizes ranging from 1 inch to 10 inches. Commonly used sizes are 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, etc., common Frequent demand promotion, such as supermarket shopping carts, logistics trolleys, tool carts, etc., use 4-6 inch freezer casters. However, if the diameter of the freezer casters is too large, the center of gravity of the equipment will rise, and the cost will increase, so we must stop comprehensive thinking. If the equipment does not require frequent advancement, such as furniture, refrigerators, etc., it is only necessary to move it when it is hygienic, and you can choose freezer casters under 3 inches.

3. Look at load-bearing: For refrigerator casters of the same diameter, ordinary manufacturers will produce several series for different load-bearing, such as light, medium, medium, etc. The way is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single freezer caster, a certain insurance coefficient should be given. When the air is relatively flat, the load of a single freezer caster = (total equipment weight ÷ number of freezer casters installed) × 1.2 (insurance coefficient); if the air is uneven, the algorithm In order, the load of a single freezer caster = the total weight of the equipment ÷ 3, because no matter what kind of uneven air, there are always at least three wheels supporting the equipment at the same time. This algorithm is equivalent to an increase in the insurance factor, more reliable, and avoid lack of load, resulting in freezer casters. Life expectancy is greatly reduced or accidents are caused. In foreign-funded companies, the load-bearing capacity is generally expressed in pounds, while most domestically, it is expressed in kilograms. Their conversion relationship is: 2.2 pounds = 1 kilogram.

4. Bracket selection: divided into directional and universal, the material is generally carbon steel, and various electroplating can be stopped, such as galvanizing, copper plating, nickel plating, chrome plating, spraying, etc., and stainless steel is also useful.

5. Brakes: In terms of function, there are wheels with brakes, those with universal brake brackets, and the two brakes are dual brakes. There are tread brakes, front brakes, side brakes, etc., please contact the freezer caster factory for details.

6. Installation method: screw rods, plungers, shrink sleeves, etc. can be used for ordinary medium and light loads, and bottom plates for heavy loads, or directly welded to the equipment. The installation methods of ordinary large companies are very generous.

7. The arrangement of the freezer casters on the equipment: The arrangement is different, which not only affects the cost, but also feels that the advancement is greatly different.

Casters are now more and more widely used in vegetable cabinets, refrigerators, freezers and other freezer equipment, and their roles are becoming more and more obvious. Therefore, when configuring freezer casters, you must choose from multiple aspects to ensure service life and application performance. , In order to play the role of casters on the freezer.
