Shaftless plastic unpowered rollers have the following advantages:
1. Light weight: - The plastic material itself has a relatively low density, making the overall weight of shaftless plastic unpowered rollers lighter, which is convenient for handling, installation, and debugging. In some occasions where equipment positions need to be frequently changed or there are strict restrictions on equipment weight, such as small logistics warehouses and temporarily built conveyor lines, its advantages are particularly obvious. This can not only reduce the labor intensity of workers but also reduce the requirements for installation foundations and save installation costs.
2. Strong corrosion resistance: - Plastic has good corrosion resistance and can resist the erosion of various chemical substances. In some special working environments, such as the chemical industry and food processing industry, corrosive substances such as acids, alkalis, and salts may be encountered. Shaftless plastic unpowered rollers can operate stably for a long time in such harsh environments and are not easy to rust or corrode, greatly extending the service life of the equipment.
3. Low operating noise: - The plastic material has better elasticity. During the operation of the roller, it can absorb and buffer the vibrations and impacts generated by material transportation or roller rotation, thereby reducing operating noise. This is a very important advantage for places that need to maintain a quiet working environment, such as libraries, electronics factories, hospitals, etc. Compared with metal rollers, shaftless plastic unpowered rollers can effectively reduce the impact of noise on workers and the surrounding environment.
4. Less damage to goods: - The surface of plastic is relatively soft. When in contact with goods, it will not easily cause scratches, wear and other damages to the surface of goods like metal rollers. Especially for some goods with high surface quality requirements, such as electronic products, glass products, precision instruments, etc., shaftless plastic unpowered rollers can provide a more safe and reliable transportation method to ensure the appearance quality and integrity of goods.
5. Unique advantages of shaftless design: Avoid material entanglement: The shaftless design eliminates the existence of a central shaft, making the internal space of the roller more open. For some materials that are easy to entangle, such as ribbons, filaments, and slender shapes, shaftless plastic unpowered rollers can effectively prevent materials from entangling on the shaft during transportation and ensure smooth transportation. For example, in the textile industry, for the transportation of materials such as yarn and fabric, shaftless plastic unpowered rollers can well meet the requirements. - Easy to clean and maintain: The structure without a central shaft makes it difficult for dust, dirt, and debris to accumulate inside the roller, making cleaning more convenient and quick. In industries with high hygiene requirements such as food processing and pharmaceutical manufacturing, this advantage of shaftless plastic unpowered rollers can ensu-re the cleanliness of transportation equipment and meet the hygiene standards and specifications of the industry.
6. Low cost: - On the one hand, the cost of plastic materials is relatively low, and the processing technology is relatively simple and the production efficiency is high, making the manufacturing cost of shaftless plastic unpowered rollers low. On the other hand, due to its good corrosion resistance and long service life, it can reduce the maintenance and replacement costs of equipment during long-term use, and the comprehensive cost advantage is obvious.
7. Good energy-saving effect: - Unpowered rollers themselves rely on external power drive, such as the gravity of goods or the push of other mechanical devices to achieve rotation. Due to the light weight and small rotational resistance of shaftless plastic unpowered rollers, under the same driving conditions, they can utilize external power more efficiently and reduce energy consumption, and have a better energy-saving effect. This is an important consideration factor for some enterprises with strict requirements on energy consumption.
The installation of unpowered roller bearings can be carried out according to the following steps: I. Preparation before installation Inspect the bearings and rollers. Check whether the bearings are damaged, rusted, etc. to ensure good bearing quality. Check whether the surface of the roller is smooth and free of burrs, protrusions and other defects to avoid affecting the installation and use of the bearings. Prepare installation tools. According to the size and installation method of the bearings, prepare appropriate installation tools such as sockets, presses, hammers, etc. Prepare an appropriate amount of grease for lubrication after bearing installation.
II. Installation process Clean the installation parts. Use tools such as cleaners or sandpaper to clean the installation parts of the roller shaft and bearing seat, and remove impurities such as oil stains, dust and rust. Install the bearing. Gently put the inner ring of the bearing on the roller shaft to ensure a tight fit between the inner ring of the bearing and the shaft. If the fit between the inner ring of the bearing and the shaft is too loose, a copper rod or hammer can be used to gently tap the inner ring of the bearing to install it in place. Install the outer ring of the bearing in the bearing seat to ensure a tight fit between the outer ring of the bearing and the bearing seat. If the fit between the outer ring of the bearing and the bearing seat is too loose, tools such as a press or socket can be used to press the outer ring of the bearing into the bearing seat. Fix the bearing. Use fixing parts such as snap rings and nuts to fix the bearing on the roller shaft and bearing seat to prevent the bearing from loosening or falling off during use. Lubricate the bearing. After the bearing is installed, add an appropriate amount of grease to ensure the normal operation of the bearing. The type and amount of grease should be determined according to the type of bearing, working conditions and usage requirements.
