UK211-2S Taper Bore Spherical Insert Ball Bearing Double 2S Contact Seal 55x100mm Conveyor Farm Machinery

The UK211-2S taper bore spherical insert ball bearing is designed for heavy-load transmission equipment, adopting 1:12 tapered inner bore matched with adapter sleeve H2311, equipped with double-sided 2S contact rubber seal for superior dustproof performance.
It is widely used in agricultural harvesting machinery and heavy conveyors where dusty environment and alternating heavy load exist.

• Stable heavy radial & axial load capacity for agricultural and heavy conveying applications
• 1:12 tapered bore + adapter sleeve locking design, uniform clamping force for precise shaft fixing
• Spherical outer ring self-aligning design to offset shaft installation deflection and housing misalignment
• Double-sided 2S multi-lip seal blocks dust, farm mud, crop residues and splash water effectively
• Stamped steel cage anti-deformation under long-time continuous heavy vibration
• Built-in grease fitting supports on-site relubrication to extend service life
• Custom design available (C3 clearance, open type, heavy mud-proof reinforced seal)
