21304 SPHERICAL ROLLER BEARING nrog 20MM BORE
Feem ntau tus kheej kheej cov menyuam bearings yog tsim los nrog ob kab ntawm cov menyuam, tso cai rau lawv nqa hnyav radial loads thiab hnyav axial loads. Kuj tseem muaj cov qauv tsim nrog ib kab ntawm cov chais, haum rau qis radial loads thiab zoo li tsis muaj axial load.
Nrog rau lub nplhaib sab hauv, tus kheej kheej cov menyuam kabmob 21304 muab cov kev sib raug zoo ntawm kev ua yuam kev. Nws muaj ob lub nplhaib nrog lub thoob-zoo li tus yob li dov cov ntsiab lus thiab tuaj yeem nqus cov radial siab heev thiab tseem muaj zog axial. Qhov loj me raws li DIN 635-2.
Cov yam ntxwv ntawm SPHERICAL ROLLER BEARING
1.Spherical roller bearing nrog ob kab ntawm cov menyuam
2.pivoting puab nplhaib, misalignments thiab ncej deflections yuav tau them
3.suitable rau siab heev radial thiab kuj siab axial loads nyob rau hauv ob qho tib si kev taw qhia
4.medium series nrog compact qhov ntev thiab nruab nrab qhov hnyav
5.cage khoom: tooj dag. Hlau, tshwj xeeb lub zog thiab durability nyob rau hauv huab mob xws li poob siab loads thiab vibrations, siab acceleration rog thiab tsis muaj lubrication.
6.seal: qhib (tsis muaj foob); rau siab dua speeds dua nrog kaw spherical roller bearings thiab yooj yim relubrication
7.zoo ruaj bearing khoom, tab sis kuj yuav siv tau raws li ib tug floating bearing, txhua yam nyob rau hauv ob qho tib si cov lus qhia
