Bearing Application
NNU49/670-S-M-C3 bearing yog tsim rau cov ntawv thov kev lag luam uas xav tau qhov kub thiab txias, hnyav loads, thiab siab rigidity, tshwj xeeb tshaj yog raws li ib tug tseem ceeb pab txhawb nyob rau hauv dov mills thiab ntawv machinery.
Nws tsim optimizes lubrication kev ua tau zoo thiab sib dhos stability. Thaum ua ke nrog cov kev sib khi thiab lubrication uas tsim nyog (xws li roj- cua lubrication), nws tuaj yeem txhim kho cov cuab yeej siv lub neej thiab kev ua haujlwm zoo. Yog hais tias siv nyob rau hauv ib tug ntsug mounting configuration, yuav tsum tau them nyiaj mloog mus rau lub sealing kev taw qhia kom tsis txhob muaj roj to los yog paug.
1. Steel Rolling Machinery:Kub/Cold Rolling Mill Roll Systems - Raug rau siab heev radial rog, yuav tsum muaj kev cuam tshuam thiab rigidity siab; feem ntau siv ua ke nrog thrust bearings.
2. Papermaking Machinery:Daim Ntawv Calendering Rolls, Qhuav Lub tog raj kheej txhawb nqa - Ua kom ruaj khov ntawm kev ua haujlwm siab thiab tiv thaiv qhov cuam tshuam ntawm qhov chaw ntub thiab kub.
3. Heavy-Cov Khoom Siv Hluav Taws Xob:Loj Gearboxes, Reducers - Txhawb nqa ntev ncej, them nyiaj rau me me misalignments, thiab C3 clearance accommodates kub nce.
4. Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv Mining:Cua Turbine Main Shaft Auxiliary Supports, Mining Mills - Muab kev txhawb nqa txhim khu kev qha nyob rau hauv kev ua haujlwm hnyav, ncua kev txij nkawm.
