Njengoba zakhiwe ngendlela efanayo njengama-ball bearing, ama-roller bearing anokuxhumana komugqa kunokuba abe ukuxhumana kwephuzu, okwenza kube namandla amakhulu kanye nokumelana okukhulu kokushaqeka. Ama-roller ngokwawo eza ngezimo eziningana, okungukuthi, ayindilinga, ayindilinga, anciphile, kanye nenaliti. Ama-roller bearing e-cylindrical aphatha imithwalo yokusunduza elinganiselwe kuphela. Ama-roller bearing ayisiyingi angamelana nokungahambisani kahle kanye nokusunduza okwengeziwe, futhi, uma ephindwe kabili, asunduze kunoma iyiphi indlela. Ama-roller bearing anciphile angaphatha imithwalo yokusunduza ebalulekile. Ama-needle bearing, uhlobo lwama-roller bearing e-cylindrical, angaphatha imithwalo ephezulu ye-radial ngobukhulu bawo, futhi angenziwa njengama-roller bearing e-needle roller.

Ama-roller bearings ayatholakala njengemiklamo ehambisanayo futhi ama-needle bearings cishe njalo azoba ngale ndlela. Ama-needle bearings asebenza kahle kakhulu ngokunyakaza okuphindaphindayo, kodwa ukungqubuzana kuzoba phezulu ngenxa yokuhlikihla ama-roller-and-roller.

Uma usebenzisa ama-roller bearings ayisilinda kuma-shafts ane-angular misalignment, kungcono ukusebenzisa ama-roller bearings amabili amafushane alandelanayo kunokusebenzisa i-roller bear eyodwa ende.

Ukukhetha i-Ball noma i-Roller Bearing
Njengomthetho ojwayelekile, ama-ball bearing asetshenziswa ngesivinini esiphezulu kanye nemithwalo elula kune-roller bearing. Ama-roller bearing asebenza kangcono ngaphansi komthwalo wokushaqeka kanye nowokushayisana.

Ama-ball bearings avame ukuthengiswa njengezinhlangano futhi ashintshwa nje njengamayunithi. Ama-roller bearings angahlukaniswa futhi i-roller carrier nama-roller, noma imijaho yangaphandle noma yangaphakathi, ishintshwe ngayinye. Izimoto ezishayela ngemuva zisebenzisa amalungiselelo anjalo kumasondo angaphambili. Inzuzo yalo mklamo ukuthi imijaho ingancishiswa ilingane emigodini nasezindlini ukuze kudalwe izinhlangano ezihlala njalo ngaphandle kokufaka engozini umonakalo kuma-roller ngokwawo.

Ama-bearings ebhola anomugqa owodwa ajwayelekile futhi angasetshenziswa ngokushintshana phakathi kwabakhiqizi. Ama-bearings e-roller awajwayelekile kangako ngokomthetho ngakho-ke umuntu ocacisayo udinga ukubheka ikhathalogi yomkhiqizi ukuze akhethe eyodwa efanelekile kuhlelo lokusebenza.

Ama-rolling-element bearing akhiqizwa ngesilinganiso esithile se-internal clearance. Noma yikuphi ukungalungi okumane kususe ibhola endaweni yalo bese kususa le-internal clearance akufanele kube nomthelela omkhulu empilweni ye-bearing. Ama-roller bearing azwela kakhulu ekungalungini kwe-angular. Isibonelo, i-ball bearing esebenza ngesivinini esimaphakathi enokulingana okukhululekile ingasebenza ngempumelelo ngokungalungi kwe-angular okuphezulu njengo-0.002 kuya ku-0.004 in./in. phakathi kwe-bearing kanye ne-shaft. I-cylindrical roller bearing, uma kuqhathaniswa, ingaba senkingeni uma ukungalungi kudlula u-0.001 in./in. Abakhiqizi ngokuvamile bazohlinzeka ngezinhlobo ezamukelekayo zokungalungi kwe-angular kuma-bearing abo ngabanye.
