Plastic waje spherical bearings

Abubuwan da ke ciki da waje suna amfani da filastik na injiniya a matsayin albarkatun kasa, wasu kuma suna amfani da karfe mai juriya a matsayin albarkatun kasa. Jikin madaidaiciya gabaɗaya yana amfani da kwallon gilashi, bakin karfe da kuma kwandon yumbu. Maintainer zaɓi injiniya roba da fiber gilashi karfafa da nylon 66 (PA66) da PE ko mafi girma yi. High daidaito roba bearings yawanci amfani da daidaito CNC machining, bearings ne mafi kyau a juyawa daidaito da kuma haƙuri. Yawancin filastik bearings na gargajiya suna amfani da ƙirar allura kai tsaye, saboda sauƙin ƙirar da ke da babban farashi. (Wheels yawanci amfani da wannan tsari) dace da amfani a lokacin da low juyawa gudun, matsakaicin kaya. Ana amfani da su sosai a masana'antar kayan wasa, masana'antar kayan aikin motsa jiki, masana'antar kayan daki, masana'antar inji na likita, masana'antar talla, masana'antar da ke da lalata mai rauni.
