Whatsapp:+86 15628905595 livia@hkbearingservice.com
Mae gan FC-type fodrwy fewnol annatod + dwy fodrwy allanol (-bach-i-ddeddfau rholio bach, manylder uchel, cyflymder uchel); Mae gan FCD-type ddwy fodrwy fewnol ar wahân + dwy fodrwy allanol (-i-gyddfau rholyn canolig, capasiti llwyth uwch, cydosod haws ar gyfer diamedrau mawr). Mae'r ddau yn Bearings rholer silindrog pedair rhes ar gyfer melinau rholio, dim ond yn cario llwythi rheiddiol, strwythur gwahanadwy.
FC:Fein rhes,Cylindrical, cylch mewnol sengl
FCD:Fein rhes,Cmelyn,Dcylchoedd mewnol ouble
Math o FC
Modrwy fewnol: 1 cylch mewnol sengl, solet, annatod (un darn, pedair rasffordd)
Cylch allanol: 2 gylch allanol ar wahân (pob un â rasffyrdd dwbl + asennau ochr + asen ganol)
Cydrannau: 1 cylch mewnol + 2 cylch allanol + 4 rhesi rholio + 2 cewyll (math crib / pres wedi'i beiriannu)
Ystod maint tyllu: yn nodweddiadol80–260 mm(gyddfau rholyn bach i ganolig)
FCD-Math
Modrwy fewnol: 2 gylch mewnol ar wahân (pob un â rasffyrdd dwbl, dim asennau; sy'n cyfateb i ddau gyfeiriant rhes ddwbl NN wedi'u cyfuno)
Cylch allanol: 2 gylch allanol ar wahân (yr un fath â FC: llwybrau rasio dwbl + asennau ochr + asen ganol)
Cydrannau: 2 gylch mewnol + 2 cylch allanol + 4 rhesi rholio + 2 cawell (pres / dur)
Ystod maint tyllu: yn nodweddiadol260–400 mm(gyddfau rholio canolig i fawr)
| Paramedr | Math o FC | FCD-Math |
| Capasiti llwyth radial | Is (cyfrif rholer llai / diamedr) | Uwch (rholeri mwy, gwell dosbarthiad llwyth) |
| Cyflymder cylchdro | Cyflymder terfyn uwch (cylch mewnol annatod=gwell anhyblygedd / manwl gywir) | Ychydig yn is (dau gylch mewnol=goddefiant cydosod bychan) |
| Anhyblygrwydd a manwl gywirdeb | Uwch (cylch mewnol un darn, llai o glirio) | Da ond yn is na FC (dau gylch mewnol gyda bwlch bach) |
| Cynulliad / dadosod | Anos i ddiamedrau mawr (cylch mewnol annatod sy'n anodd ei osod ar gyddfau rholiau mawr) | Haws ar gyfer diamedrau mawr (rhannu cylchoedd mewnol ffitio'n hawdd) |
| Cymwysiadau nodweddiadol | Melinau rholio oer (4-uchel / 6-uchel / 12-uchel) rholiau gwaith, rholiau diamedr bach cyflym | Melinau rholio poeth, melinau adran, melinau gwialen gwifren cyflym, rholiau wrth gefn / rholiau canolradd ar gyfer melinau canolig-mawr |
