LKU207-2F Taper Bore Insert Bearing + H2307 Adapter Sleeve, Double 2F Anti-Mud Composite Seals

LKU 207 2F tapered bore spherical insert bearing matched with H2307 withdrawal sleeve, equipped with KM7 locknut and MB7 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 heavy mud, crop residues, industrial dust and water splashes efficiently. Side grease nipple supports regular relubrication, widely applied to medium-heavy agricultural machines, grain sorting lines, heavy belt conveyors, feed processing and 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.
• H2307 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under medium-heavy 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-heavy radial load capacity.
• Standard 35mm taper bore size, fully interchangeable with single-seal LKU207+H2307 sets for direct heavy-duty sealing upgrade.

Q1: What benefits does H2307 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.

Q2: Where to use LKU207-2F + H2307 bearing assembly?

Fit medium-heavy agricultural machines, transport and grain processing equipment working in muddy, dusty environments with daily medium-heavy vibration.

Q3: Can I replace standard single-seal LKU207+H2307 directly?

Yes, all mounting and dimension parameters are identical for direct upgrade to heavy-duty mud-resistant version.
