NNTR90X220X100-2ZL taug qab cov menyuam bearings, Txhawb cov menyuam, nrog flange rings, nrog ib lub nplhaib puab
Kev them nyiaj yug rollers nrog flange rings yog cov tsis sib cais
Qhov no bering muaj ntau flange tsim:
1.pressed-on flange rings (NATR thiab NATV tsim)
2.loose flange rings (NUTR, PWTR thiab NNTR tsim)
3.accommodate axial loads uas tuaj yeem tshwm sim vim skew lossis tilting
NNTR ... 2ZL tsim kev txhawb nqa rollers yog ua raws li ob kab tag nrho ntxiv cylindrical cov menyuam bearings.
NNTR... 2ZL Series bearing muaj lub nplhaib sab nraud nrog peb lub flanges, uas coj cov menyuam teeb tsa axially.
NNTR... 2ZL Series bearing muaj lub nplhaib puab nrog ob lub nplhaib flange, uas coj lub nplhaib sab nraud ntawm cov menyuam txheej.
Cov kabmob no muaj cov roj ntau ntau ntawm cov menyuam yaus thiab haum nrog lamellar foob ntawm ob sab, tso rau hauv qhov chaw nyob hauv lub xub pwg nyom ntawm flange rings thiab lub nplhaib sab nraud, ua rau cov menyuam tsis sib cais.
Nws haum rau hnyav radial loads thiab hnyav axial loads uas tuaj yeem tshwm sim vim skew lossis tilting.
