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 burn, fine processing, high quality, longer use
