Cov khoom siv bearing tuaj yeem muab faib ua ntau hom raws li lawv qhov muaj pes tsawg leeg thiab kev siv. Cov pawg tseem ceeb suav nrog:
1. Cov khoom siv hlau bearing:
Chromium steel (52100, GCr15) - Cov hom feem ntau yog rau dov bearings, nrog siab hardness thiab zoo hnav tsis kam.
Stainless hlau (440C, 304, 316, thiab lwm yam) - Corrosion-resistant, siv nyob rau hauv marine thiab zaub mov industries.
Cov pa roj carbon steel - Tus nqi qis, siv rau qis- daim ntawv thov thauj khoom.
Cov cuab yeej steel - Siab zog, siv nyob rau hauv huab cua load.
Bronze bearings - Zoo hnav tsis kam thiab tus kheej- lubrication, feem ntau siv rau bushings.
Copper bearings - Zoo ib yam li tooj liab, tab sis muaj zog me ntsis.
Babbitt alloy (dawb hlau) - Cov hlau mos, siv rau zawv zawg bearings hauv cav thiab turbines.
2. Tsis yog-cov khoom siv hlau
Ceramics (zirconia, silicon nitride, alumina) - Kub resistant, tsis yog -magnetic, siv nyob rau hauv siab - daim ntawv thov ceev.
Polymers/plastics (PTFE, nylon, PEEK, UHMWPE, thiab lwm yam.) - Lub teeb, corrosion{2}}resistant, nws tus kheej-lubricating, siv nyob rau hauv kev kho mob thiab zaub mov daim ntaub ntawv.
Carbon/graphite bearings - Tus kheej-lubricating, siv nyob rau hauv huab cua kub thiab tshuaj ib puag ncig.
