The bearing industry uses different materials to make different bearing components, and engineering plastics is one of the outstanding materials. The plastic is processed through a series of processes to achieve a longer life by achieving the desired properties.
Bearings can be divided into two categories, plastic bearings and metal bearings. Plastic bearings are mainly processed by profile machining and injection molding. Plastic bearings are mainly processed by profile machining and injection molding, and are more diversified in the molding process, which greatly improves production efficiency and reduces enterprise costs.
HDPE, PP and other engineering plastics have been proven to be used in relatively weak acid-base cross-environment, with oil-free self-lubricating and anti-magnetic electrical insulation properties of general engineering plastic bearings.
The steps for selecting a plastic bearing may be summarized as follows: according to the working conditions of the plastic bearing, the basic type of bearing, the tolerance class and the clearance are selected; according to the working conditions of the plastic bearing, the force condition and the life requirement; the rated load and the speed of the selected plastic bearing are checked. frequency.
The wear resistance of engineering plastic bearings mainly depends on the wear resistance of the bearing materials themselves, but the wear of engineering plastic bearings is also closely related to the following factors: grinding shaft material, hardness, roughness, bearing running speed, load and ambient temperature and humidity.
