LKU206-2F Taper Bore Insert Bearing + H2306 Adapter Sleeve, Double 2F Anti-Mud Composite Seals

LKU 206 2F tapered bore spherical insert bearing matched with H2306 withdrawal sleeve, equipped with KM6 locknut and MB6 lock washer. Double-sided 2F composite seals adopt centrifugal metal flinger + NBR rubber lip two-stage barrier. The 1:12 taper sleeve delivers uniform full-circle clamping without scratching shaft surfaces. Spherical outer ring provides ±2.5° self-alignment to offset shaft assembly misalignment. Dual-layer sealing blocks mud, crop residues, industrial dust and water splashes efficiently. Side grease nipple supports regular relubrication, widely applied to medium agricultural machines, grain sorting lines, belt conveyors, feed processing and light-medium construction transmission equipment.

• Dual 2F anti-contamination seal: Metal flinger throws mud and debris away via centrifugal force; inner rubber lip isolates fine dust and moisture, outperforming single 2S rubber seals in muddy, dusty working environments.
• H2306 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under medium vibration and frequent forward-reverse rotation.
• ±2.5° self-aligning spherical outer ring eliminates extra internal stress caused by shaft deflection and assembly offset, reducing abnormal bearing wear and running noise.
• Side grease fitting enables periodic supplementary lubrication to extend heavy-load service cycle and cut maintenance downtime.
• GCr15 fully heat-treated bearing steel with stable medium radial load capacity.
• Standard 30mm taper bore size, fully interchangeable with single-seal LKU206+H2306 sets for direct heavy-duty sealing upgrade.

1. Q1: What benefits does H2306 sleeve locking have over set screw locking?
   Taper sleeve provides uniform full-circle clamping force, no shaft scratches, stronger anti-slip effect under vibration and impact loads.

2. Q2: Where to use LKU206-2F + H2306 bearing assembly?
   Fit medium agricultural machines, transport and grain processing equipment working in muddy, dusty environments with daily medium vibration.

3. Q3: Can I replace standard single-seal LKU206+H2306 directly?
   Yes, all mounting and dimension parameters are identical for direct upgrade to heavy-duty mud-resistant version.
