LK211-2F Taper Bore Spherical Insert Ball Bearing Double 2F Contact Seal 55x100mm Conveyor Farm Machinery

The LK211-2F taper bore spherical insert ball bearing is designed for heavy-duty transmission equipment, featuring 1:12 tapered inner bore matched with H2311 adapter sleeve. Double-sided reinforced 2F multi-lip NBR seals deliver superior anti-dust and anti-mud performance, with built-in grease fitting for regular relubriion maintenance.
It is widely installed on large agricultural harvesters and heavy conveyors operating in dusty, muddy working sites with alternating heavy loads.

• High heavy radial & axial load bearing capacity for large farm machinery and heavy conveying equipment
• 1:12 taper bore cooperates with H2311 sleeve to generate even clamping force for firm shaft locking
• Spherical outer ring self-aligns automatically to compensate shaft deflection and housing assembly misalignment
• Dual 2F reinforced labyrinth multi-lip seal effectively blocks heavy dust, crop residues and splashing muddy water
• High rigidity stamped steel cage maintains stable structure under long-term continuous heavy vibration
• Grease nipple design supports on-site refueling to greatly extend bearing service life
• Custom options available: C3 internal clearance, open seal version, heavy mud reinforced sealing structure
