1---What is a swivel caster?
The swivel caster is called the driving wheel, which allows the structure to rotate 360 degrees. Caster is a general name that includes both movable and fixed casters. Fixed casters have no rotating structure and cannot rotate horizontally, only vertically. These two types of casters are generally used. For example, the structure of a cart is two fixed wheels at the front, and arms close to the two driving wheels at the back.

2---The use and characteristics of swivel casters:
1. Swivel casters can be widely used in factories, workshops, commerce, catering and other industries.
2. You can also choose different casters according to the environmental carrying capacity.
3. There are two types of casters: ball bearings and roller bearings.
4. The braking system is installed on the casters.
5. The bracket is shot peened and galvanized, which is beautiful and corrosion-resistant.
6. Casters of different materials can be selected according to different usage environments.

3---Materials and applications of universal casters:
1. There are universal joints made of various materials. The most commonly used materials are: nylon, polyurethane, rubber, cast iron and other materials.
2. Suitable for mining, mechanical equipment, electronic equipment, medical equipment, decoration engineering, textiles, printing and dyeing, furniture, equipment, logistics and warehousing, turnover vehicles, chassis, cabinets, equipment, electromechanical, dust-free workshops, production lines, large supermarkets, etc. Industries and fields;

4---Correct use of swivel casters:
1. Casters must be installed at the manufacturer's design point.
2. The installed scaffolding must have sufficient strength to meet the weight of use.
3. The installation device cannot change or affect the function of the casters.
4. The axis of rotation must always be vertical.
5. Fixed casters must be in a straight line from caster to caster.
6. If only swivel casters are used, they must be consistent.
7. If fixed casters are used together with swivel casters, all casters must be compatible with each other and must be used by the manufacturer.

5--- How to choose a suitable universal wheel:
1. Select caster material: first consider the size of obstacles on the road, and use the weight of the slag yard (such as iron, oil), environmental conditions (such as high temperature, normal temperature or low temperature) under different conditions and the capacity of the caster to select the appropriate one. caster material. For example, rubber wheels cannot withstand acids, oils, and chemicals. High-tech polyurethane casters, modified nylon wheels, and high-temperature-resistant casters can be used in different special environments.
2. Calculate the load-bearing weight: In order to calculate the load-bearing capacity of various universal wheels, it is necessary to know the weight, maximum load, and number of single wheels and universal wheels of the transportation equipment. The load-bearing capacity of a single wheel is calculated as follows: T=(e + z) / M=N: T=load-carrying capacity of a single wheel or universal wheel; e=self-weight of transportation equipment; z=maximum load; number of single wheels and universal wheels It is m==; n=safety factor (about 1.3~1.5).
3. Determine the size of the caster diameter. Generally speaking, the larger the diameter of the universal wheel, the easier it is to push, the greater the load-bearing capacity, and the better the protection of the ground. The selection of caster diameter should first consider the load-bearing capacity and starting thrust of the truck under load.
4. Rotation flexibility: The larger the single wheel, the more labor saved. Roller bearings have heavier loads and greater resistance when rotating. Single wheel ball bearings can carry heavier loads, making rotation lighter, more flexible and quieter.

6---How to maintain the universal wheel:
1. Whether the welding point or welding layer is damaged;
2. Are the nuts and bolts loose?
3. Check whether the casters are deformed.
4. If it is a universal wheel with a rod, the installation hole of the device is not bent and is tightly connected with the plug.
5. Install the casters using lock nuts or lock washers.
6. Confirm whether the installation position of the expansion rubber sleeve is fixed.
7. Add lubricant;
