LK212-2F+H2312 Taper Bore Spherical Insert Bearing With H2312 Adapter Sleeve Double 2F Seal 55x110mm Conveyor Farm Machinery

The LK212-2F+H2312 complete assembly consists of LK212-2F tapered bore spherical insert bearing and matched H2312 adapter sleeve, designed for heavy-duty transmission equipment. It features 1:12 tapered inner bore, double-sided 2F reinforced NBR multi-lip contact seals and built-in grease nipple for regular relubrication.
It is widely applied in large agricultural harvesters and heavy-duty conveyors under dusty and muddy environment with alternating heavy load conditions.
