EMT-1	Advantageous in high load carrying capacity, anti-impact, lower wear. Suitable for Mid-load capacity & Midhigher Sliding velocitie. Bushings for Gearbox, Rocker arm, King Pin, transmission etc.
EMT-2	Higher fatige strength & load carrying capacity, goos running characteristics at higher sliding velocities. Suitable for Mid-load capacity & Mid-Sliding velocitie . Bushings for lubricating oil pumps . After surface specifical treatment, Bushings for Main bushes of high speed internal-combustion engine, Connecting Rod etc .
EMT-3	Very Good sliding Characteristics, good anti-seizure property, special material, Punched oil grooves & oil pockets are not feasible. Bushings suitable for hydraulic Pump,automatic gearbox. After surface specifical treatme
EMT-4	Mid fatige strength & load carrying capacity, very good fatige strength & load carrying capacity, very good sliding characteristics . Bushings for half-bearing of high speed, lower load internal-combushtion engine, aircomressor, refrigerator, hypoid gearbox, hydraulic pump, gearbox etc.
EMT-5	The material composition of the product conform to the requirements of the Ro HS, under certain conditions can replace the EMT-1, has good load pressure & good wear resistance. The disadvantage is that it cannot be used without oil lubricant. But has great advantage in a well-lubricated situation. Suitable for heavy & medium load, Medium & high speed, as well as large impact loads.
