Engineering plastic square bearing seats are divided into vertical seats (P seats), square seats (F seats), diamond seats (FL seats), circular seats (C seats), convex circular seats (FC seats), convex square seats (FS seats), concealed hole seats (PA seats), and suspended seats (FA seats) 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. 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.



Engineering plastic square bearing seat (Bearing) is an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their motion, and ensure their accuracy in rotation. According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Outer ball bearing with seat, also known as bearing unit (in SKF's terminology). When there is no bearing, it is called an outer spherical bearing seat.

Application fields of outer spherical bearing seats: metallurgy, mining, environmental protection, chemical industry, light industry, textile, agricultural machinery, and mechanical equipment industries. Equipped with square seat outer spherical bearings, good fixation: the top wire end has a steel ball, which is better fixed than the top wire. Strong sealing: The outer spherical surface is double layered, providing excellent sealing performance
