LK213-2F Taper Bore Spherical Insert Ball Bearing Double 2F Contact Seal 65x120mm Farm Heavy Conveyor Machinery
The LK213-2F taper bore spherical insert ball bearing is developed for heavy-duty industrial and agricultural transmission equipment, fitted with 1:12 tapered inner bore matched with H2313 adapter sleeve. Double-sided reinforced 2F multi-lip NBR contact seals provide excellent anti-dust and anti-mud performance, equipped with built-in grease fitting for periodic relubriion maintenance.
It is widely installed on large grain harvesters, heavy mine conveyors and construction machinery working in harsh dusty, muddy sites with continuous heavy alternating loads.
