LK215-2F Taper Bore Spherical Insert Ball Bearing Double 2F Contact Seal 75x130mm Heavy Farm Mining Conveyor Machinery

The LK215-2F taper bore spherical insert ball bearing is designed for ultra-heavy load agricultural and mining transmission equipment, equipped with 1:12 tapered inner bore matched with H2315 adapter sleeve. Double-sided reinforced 2F multi-lip NBR contact seals deliver outstanding dust, mud and sewage isolation performance, with built-in grease fitting for regular relubrication maintenance.

It is widely installed on large combine harvesters, mine heavy transport conveyors and concrete mixing equipment running in severe dusty, muddy working environments with continuous heavy impact loads.

• Superior ultra-heavy radial & axial load capacity for large farm machinery and mining heavy conveying equipment
• 1:12 taper bore cooperates with H2315 sleeve to produce even clamping force for rigid shaft locking
• Spherical outer ring self-aligns automatically to absorb shaft deflection and housing assembly misalignment
• Dual 2F reinforced multi-lip sealing structure effectively blocks mineral dust, crop residues, mud and splashing wastewater
• Thickened high-rigidity steel cage maintains stable structure under long-term continuous heavy vibration and impact shocks
• Grease nipple design allows convenient on-site refueling to extend overall bearing service life significantly
• Custom options available: C3 internal clearance, open seal version, extra heavy mud resistant reinforced sealing

This bearing is widely used in:

• Ultra-heavy load mine, quarry and grain bulk transport conveyor roller support assemblies
• Large agricultural tractors, large combine harvesters, heavy soil tillage equipment and farm transmission shafts
