LKV207-2F Taper Bore Spherical Insert Bearing + H2307 Adapter Sleeve, Double 2F Flinger-Rubber Anti-Mud Composite Seals

1. Product Overview

LKV 207 2F tapered bore spherical insert bearing assembled with H2307 withdrawal adapter sleeve, complete with KM7 locknut and MB7 lock washer. 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 H2307 sleeve avoids shaft surface scratches and point pressure damage. 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 side 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.

2. Key Advantages

• 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.
• H2307 1:12 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 and premature wear.
• Reserved grease fitting enables regular supplementary lubrication to extend continuous heavy-load service cycle and cut maintenance frequency.
• GCr15 high carbon chromium bearing steel with full quenching & tempering heat treatment, stable high radial load bearing capacity.
• Standard 35mm tapered bore dimension, fully interchangeable with ordinary single-seal LKV207+H2307 assembly for direct upgrade.

Improve equipment long-term running stability and reduce downtime cost
