LKF213-2F 4-Bolt Flange Bearing With H2313 Sleeve, Double 2F Mud-Proof Seals

1. Product Overview

LKF213-2F+H2313 complete square flange bearing assembly consists of F213 four-bolt cast iron housing, UK213-2F tapered bore insert bearing and full H2313 adapter kit (KM13 lock nut + MB13 lock washer). Double-sided 2F composite seals adopt metal flinger + NBR double-lip rubber two-stage barrier to block mud, crop residues, coarse dust and cooling water splashes. 1:12 taper bore matched with H2313 sleeve fits smooth 60mm solid shafts without stepped machining, delivering uniform full-circle clamping force for stable bidirectional rotation. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly deflection. Side grease nipple supports periodic re-lubrication. Widely applied to large grain harvesters, heavy belt conveyors, grain sorting lines and feed processing equipment.

2. Key Advantages

• Dual 2F anti-fouling sealing system: Outer metal flinger throws mud clumps via centrifugal rotation; inner rubber lip isolates fine dust and water mist, far superior anti-mud performance than single-layer 2S rubber seals for muddy field environments.
• H2313 taper sleeve locking structure: Uniform full-shaft clamping without shaft scratches, reliable anti-loosening under long heavy vibration and frequent forward/reverse rotation.
• HT200 grey cast iron square flange housing, high integral rigidity, thick wall anti-impact, quick bolt mounting and easy disassembly for routine maintenance.
• ±2.5° self-aligning spherical outer ring eliminates assembly offset stress, reduces abnormal bearing friction, wear and running noise.
• Reserved side grease fitting for regular supplementary lubrication, extends bearing service life and cuts equipment downtime.
• GCr15 fully heat-treated bearing steel, high dynamic & static load capacity, excellent wear and impact resistance for continuous heavy-duty operation.
• Standard unified metric dimensions, fully interchangeable with single-seal LKF213+H2313 for direct heavy mud-proof sealing upgrade.

Lower maintenance cost and ensure stable transmission operation of heavy agricultural & industrial machinery

3. Applications
