The freezer caster wheel is an important accessory for moving the freezer. The quality of the freezer caster wheel directly affects the moving effect of the freezer in real life. So when choosing the freezer caster wheel, what aspects can you consider? Da Shi caster wheel believes that everyone can choose from the following seven points.
1. Wheel material: This is very important. Generally, there are PU, TPR, PP, rubber, nylon, etc. As for the applicable temperature, appearance hardness, air environment, etc.
2. Choose the size: The larger the diameter of the common freezer caster wheel, the more effortless the advancement, and the better the ability to overcome obstacles. Since the freezer caster wheel were first industrialized in the West in the late 19th century, the size of the freezer caster wheel is usually expressed in inches. For example, most supermarket trolleys in China use 5-inch and 4-inch freezer caster wheel. At present, the sizes of freezer caster wheel that are popular on the market range from 1 inch to 10 inches. The 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., ordinary For those who often need to promote, such as supermarket shopping carts, logistics trolleys, tool carts, etc., it is better to use 4-6 inch freezer caster wheel. However, if the diameter of the freezer caster wheel is too large, the center of gravity of the equipment will increase and the cost will increase, so it is necessary to stop comprehensive thinking. If the equipment does not need to be constantly promoted, such as furniture, refrigerators, etc., it is only necessary to move it when doing hygiene, and select the freezer caster wheel under 3 inches.
3. Look at the load-bearing: For refrigerator wheels with the same diameter, ordinary manufacturers will consume several series for different load-bearing, such as light, medium, medium, etc. The method is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single freezer caster wheel, a certain insurance factor should be given. When the air is relatively flat, the load of a single freezer caster wheel = (total weight of the equipment ÷ the number of installed freezer caster wheel) × 1.2 (insurance factor); if the air is not flat, the algorithm Because, the load of a single freezer caster wheel = the total weight of the equipment ÷ 3, because no matter what kind of uneven air, there are always at least three wheels supporting the device at the same time, this algorithm is equivalent to increase the insurance factor, more reliable, to avoid the lack of load, resulting in freezer caster wheel Life expectancy is greatly reduced or accidents are caused. In foreign-funded companies, the load-bearing capacity is usually expressed in pounds, while most domestic uses are in kilograms. Their conversion relationship is: 2.2 pounds = 1 kilogram.
4. Bracket selection: It is divided into directional and universal. The material is generally carbon steel, which can stop all kinds of electroplating, such as zinc plating, copper plating, nickel plating, chrome plating, spraying, etc. It is also useful for stainless steel.
5. Brake: In terms of function, there are brake wheels and universal brake brackets. The two brakes are double brakes, as well as tread brakes, positive brakes and side brakes. Please contact the refrigerator caster wheel factory for details.
6. Device mode: Screw rods, plungers, shrink rubber sleeves, etc. are available for ordinary medium and light loads, and base plates are used for heavy loads, or directly welded to the equipment. The installation methods of ordinary large companies are very rich.
7. The layout of the freezer caster wheel on the equipment: The layout is different, which not only affects the cost, but also feels very different.
Caster wheel are now more and more widely used in refrigerator cabinets such as vegetable cabinets, refrigerators, refrigerators, etc., and their role is becoming more and more obvious. Therefore, when configuring refrigerator cabinet caster wheel, you must choose from multiple aspects to ensure service life and application performance. , In order to play the biggest role of caster wheel on the freezer.
