Product Overview

ZWZ thrust cylindrical cov menyuam bearings muaj xws li ncej ntxhua khaub ncaws, tsev ntxhua khaub ncaws, crowned cylindrical rollers, thiab tawb sib dhos. Lub crowned nto ntawm lub rollers pab faib lub siab sib npaug ntawm cov dov cov ntsiab lus thiab raceways, muab kev ua tau zoo thiab txhim khu kev qha.

Cov no yog cov kabmob sib cais, yog li txhua yam tuaj yeem ntsia tau tus kheej. Thaum lub sij hawm kev teeb tsa, kev ua tib zoo sib xws yog tsim nyog - ncej thiab vaj tse yuav tsum nyob twj ywm raws nraim tsis muaj angular qaij. Tsim tshwj xeeb rau cov khoom siv qis- ceev, cov kabmob no txhawb nqa hnyav ib qho kev taw qhia axial loads, muab siab axial txhav, thiab tsis txwv radial txav.

Yam khoom tseem ceeb

● Optimized roller tsim kom txo tau kev ntxhov siab thiab txhawb nqa txawm tias thauj khoom, pab kom ntev kev pab cuam lub neej.
● Cov qauv sib cais tso cai rau kev txhim kho yooj yim dua, tshem tawm, thiab tu txhua hnub.
● High axial load peev xwm thiab muaj zog axial rigidity, ua rau lawv haum rau kev ua haujlwm hnyav.
● Zoo haum rau cov ntawv thov ceev uas xav tau kev txhawb nqa axial ruaj khov.
● Yuav tsum muaj kev sib raug zoo; angular misalignment ntawm ncej thiab vaj tse yog tsis tso cai.

Kev faib khoom

1. Tib-Direction Thrust Cylindrical Cov Menyuam Bearings

Tsim los nqa axial loads los ntawm ib qho kev taw qhia nkaus xwb, siv rau hauv cov khoom siv nrog unidirectional axial quab yuam.

2. Ob-Direction Thrust Cylindrical Cov Menyuam Bearings

Muaj peev xwm txhawb nqa axial loads los ntawm ob qho tib si cov lus qhia, siv qhov twg dual-direction axial qhov chaw xav tau.
