LKV209-2F Taper Bore Bearing + H2309 Sleeve, Double 2F Anti-Mud Composite Seals

LKV 209 2F tapered bore spherical insert bearing matched with H2309 withdrawal sleeve, equipped with KM9 locknut and MB9 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 farm mud, crop waste, industrial dust and water splashes efficiently. Side grease nipple supports regular relubrication, widely applied to agricultural harvesters, rotary tillers, grain sorting lines, mining conveyors, feed processing and medium construction transmission equipment.

• Dual 2F anti-contamination seal: Metal flinger throws large mud/debris away via centrifugal force; inner rubber lip isolates fine dust and moisture, outperforming single 2S rubber seals in muddy farm/mining environments.
• H2309 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under 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.
• 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 high radial load capacity.
• Standard 45mm taper bore size, fully interchangeable with single-seal LKV209+H2309 sets for direct heavy-duty upgrade.

• Grain harvesters, rotary tillers, grain drying & sorting lines
• Mining sand conveyors, mineral transport rollers
• Feed processing machinery, packaging production lines
• Medium construction auxiliary transmission assemblies

Perfect for sites with heavy mud, dust and constant vibration
