LKU208-2F Taper Bore Insert Bearing + H2308 Adapter Sleeve, Double 2F Anti-Mud Composite Seals

LKU 208 2F tapered bore spherical insert bearing matched with H2308 withdrawal sleeve, equipped with KM8 locknut and MB8 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 heavy agricultural machines, grain sorting lines, heavy belt conveyors, feed processing and mining auxiliary 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 harsh working environments.
• H2308 taper sleeve locking design: Even circumferential compression, stable anti-slip performance under heavy vibration and frequent forward-reverse rotation, easy disassembly for maintenance.
• ±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 heavy radial load capacity, strong impact resistance.
• Standard 40mm taper bore size, fully interchangeable with single-seal LKU208+H2308 sets for direct heavy-duty sealing upgrade.
