LKV206-2F Taper Bore Insert Bearing + H2306 Adapter Sleeve, Double 2F Metal Flinger Anti-Mud Composite Seals

LKV 206 2F tapered bore spherical insert bearing assembled with H2306 withdrawal adapter sleeve. Equipped with bilateral 2F two-stage composite sealing: centrifugal metal flinger + inner NBR rubber contact lip seal, no set screw locking structure. Uniform circumferential clamping via H2306 sleeve avoids shaft surface scratches. Spherical outer ring provides ±2.5° self-alignment to eliminate shaft installation misalignment stress. Double-layer 2F seal effectively blocks thick farm mud, crop straw debris, industrial dust and water splashes. Built-in grease nipple supports periodic relubrication, widely applied to agricultural harvesters, rotary tillers, grain sorting lines, mining belt conveyors, feed processing and medium construction transmission equipment.

• Dual 2F flinger-rubber double barrier seal: Metal flinger throws away large mud/debris by centrifugal force; inner rubber lip seals fine dust and moisture, far superior anti-contamination performance than single 2S rubber seals in muddy farm/mining working conditions.
• H2306 taper adapter sleeve locking: Full-circle uniform compression force, no shaft scratch, excellent anti-slip stability under heavy continuous vibration and frequent forward-reverse rotation.
• Spherical outer ring ±2.5° self-aligning design compensates shaft deflection and assembly offset, prevents abnormal internal bearing stress.
• Reserved grease fitting enables regular supplementary lubrication to extend continuous heavy-load service cycle.
• GCr15 high carbon chromium bearing steel with full quenching & tempering heat treatment, stable radial load bearing capacity.
• Standard 30mm tapered bore dimension, fully interchangeable with ordinary single-seal LKV206+H2306 assembly for direct upgrade.

Lower maintenance frequency and improve equipment long-term running stability

• Grain combine harvesters, rotary tillers, grain drying & sorting production lines
