Hlau
Hlau, ib qho alloy feem ntau muaj cov pa roj carbon thiab hlau, yog cov khoom siv nrov tshaj plaws rau cov kab bearings. Hlau linear bearings paub tias muaj cov khoom siv zoo heev (piv txwv li, lub zog siab thiab rigidity); qhov no tuaj yeem txhawb nqa hnyav thiab muab kev sib tw thiab meej. Carbon steel thiab stainless hlau yog hom hlau siv hauv kev tsim cov hlau linear bearings. Ua kom cov ntsiab lus carbon tsub kom qhov hardness ntawm steel; Qhov no cuam tshuam rau kev ua haujlwm ntawm cov kabmob linear.
Aluminium
Aluminium yog lub teeb yuag tab sis muaj zog hlau. Nws yog corrosion thiab tshuaj resistant. Nws yog softer thiab tsis kim tshaj steel. Txawm li cas los xij, aluminium linear bearings muaj peev xwm qis dua li steel linear bearings. Aluminium linear bearings kuj muaj peev xwm muab kev sib tw thiab meej.
Cov yas
Yas linear bearings yog softer, pheej yig dua, thiab muaj qis coefficient ntawm kev sib txhuam dua li cov kabmob hlau. Cov yas uas siv hauv cov kab bearings yog nylon, polyethylene, thiab PVDF, thiab lawv feem ntau yog lined nrog tus kheej-lubricating txheej (xws li, PTFE). Qee zaum lawv tau ntxiv nrog fibers thiab fillers los txhim kho lawv qhov hnyav-kev muaj peev xwm. Yas linear bearings tuaj yeem siv nrog cov ntaub ntawv softer. Txawm li cas los xij, lawv feem ntau muaj peev xwm qis dua thiab txwv rau chav tsev kub.
Bronze
Bronze yog ib qho alloy feem ntau tsim los ntawm tooj liab thiab zinc, nrog rau lwm yam additives xws li manganese thiab phosphorus. Nws yog cov hlau mos. Bronze linear bearings muaj peev xwm thauj khoom ntau dua li cov yas linear bearings. Vim tias muaj kev sib cuag ntawm cov hlau-rau-hlau, txawm li cas los xij, lawv tsim kev sib txhuam ntau dua li cov kabmob yas; Qhov no yuav tsum tau saib xyuas kom txaus lubrication.
Ceramics
Ceramic linear bearings feem ntau yog tsim los ntawm silicon nitride, aluminium oxide, zirconium oxide, thiab silicon carbide. Lawv muaj rigidity siab, uas tswj kev mus los qhov tseeb thiab precision ntawm high speeds. Lawv muaj ib tug siab hardness, uas ua rau lawv cov kev pab cuam lub neej thiab puas kuj thiab txo cov generated hais los ntawm zawv zawg ntawm bearing Cheebtsam. Lawv kuj sib xws nrog lub tshuab nqus tsev thiab ESD-sensitive li thiab khoom siv.
