Rubber Lagging Pulley

Roj hmab lagging pulley yog los npog ib txheej roj hmab rau saum npoo ntawm lub nruas steel los ntawm cov txheej txheem kub vulcanization lossis kev sib txuas txias, uas yog siv los txo qhov hnav ntawm cov hlau thiab tiv thaiv kom ntev kev pab cuam lub neej ntawm txoj siv conveyor.
