LK210-2F Taper Bore Spherical Insert Ball Bearing Double 2F Contact Seal 50x90mm Conveyor Farm Machinery
The LK210-2F taper bore spherical insert ball bearing is engineered for heavy load transmission equipment, equipped with a 1:12 tapered inner bore matched with H2310 adapter sleeve. Double-sided 2F reinforced multi-lip NBR seals deliver excellent dust and mud resistance, with built-in grease fitting for regular lubriion maintenance.
It is widely fitted on large agricultural tractors and heavy-duty conveyors operating in dusty, muddy working environments with alternating heavy loads.
