LK212-2F Taper Bore Spherical Insert Ball Bearing Double 2F Contact Seal 60x110mm Conveyor Farm Machinery
The LK212-2F taper bore spherical insert ball bearing is designed for heavy-duty transmission equipment, adopting 1:12 tapered inner bore matched with adapter sleeve H2312, equipped with double-sided 2F reinforced NBR multi-lip contact seal for excellent dust and mud resistance. Built-in grease fitting supports regular relubriion maintenance.
It is widely installed on large agricultural harvesters and heavy conveyors running in dusty muddy sites with alternating heavy loads.
