Plastic bearing with seat is unique in its light weight, easy installation, maintenance free, and has shock absorption and impact resistance performan
Product details
Plastic belt seat bearings are characterized by their light weight, easy installation, maintenance free, and lack of shock absorption and impact resistance compared to commonly used cast iron or stamped seats. With the continuous development of new materials, they are increasingly being widely used in engineering. For different situations, plastic outer spherical bearings can be made of different materials such as POM, HDPE, PP, UPE, PTFE, etc. The plastic bearing seat is generally made of PBT material. Application fields of outer spherical bearing seats: metallurgy, mining, environmental protection, chemical industry, light industry, textile, agricultural machinery, and mechanical equipment industries. The outer spherical bearing seat is divided into vertical seat (P seat), square seat (F seat), diamond seat (FL seat), circular seat (C seat), convex circular seat (FC seat), convex square seat (FS seat), concealed hole seat (PA seat), and suspended seat (FA seat) according to their shapes
Features: High speed, low friction, low noise, load and high temperature resistance, not easy to overheat, fine processing, high quality, longer use.
The main raw material for plastic bearing seats is PBT engineering plastic. Before PBT injection molding, it must be dried at a temperature of 110-120 ℃ for about 3 hours. The molding processing temperature is 250-270 ℃, and the mold temperature should be controlled at 50-75 ℃. As the material solidifies and crystallizes immediately upon cooling from a molten state, its cooling time is relatively short; If the nozzle temperature is not properly controlled (too low), the flow channel (water outlet) is prone to cooling and solidification, leading to nozzle blockage. If the temperature of the barrel exceeds 275 ℃ or the molten material stays in the barrel for more than 30 minutes, it is easy to cause the material to decompose and become brittle. When PBT injection molding, a larger nozzle is required for injection molding, and a hot runner system should not be used. The mold exhaust should be good, and it is recommended to use "high speed, medium pressure, and medium temperature" conditions for molding and processing. Fireproof materials or PBT nozzle materials with added fiberglass should not be recycled. When stopping the machine, PE or PP materials should be used to clean the material pipe in a timely manner to avoid carbonization.
