OMT-DU-LF

Self lubricating bearing with stainless steel backing provides high load carrying capacity and very high level of resistance in corrosive environments.

Features : Suitable for dry running, low coefficient of friction, lower

wear, good sliding characteristics, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling. Also performs well with lubrication. Stainless steel backing provides improved corrosion resistance compared with SF-1 and SF-2.

Application : The high level of resistance in corrosion environment provides good application for chemical industry like chemical valve, chemical pump, flow meter, food industry and pharmaceutical industry etc.
