1. Product Overview

LEU 210 2F integrated vertical V-shaped grey cast iron bearing unit, matched with YEL210-2F eccentric lock insert bearing with double extended inner ring. Bilateral 2F composite seal adopts centrifugal metal flinger + NBR rubber lip two-stage labyrinth barrier structure. Eccentric locking collar fastens extended inner ring for stable constant one-way rotation. Spherical outer ring provides ±2.5° self-alignment to offset shaft assembly misalignment. Dual-layer sealing effectively blocks thick mud, crop residues, industrial dust and splashing water. Side grease nipple supports periodic re-lubrication, widely used on heavy rotary tillers, large grain harvesters, heavy-duty belt conveyors, packaging and textile machinery.

2. Key Advantages

• Dual 2F anti-contamination sealing system: Metal flinger throws large mud and debris away by centrifugal force; inner rubber lip isolates fine dust, moisture and water mist, far superior to single 2S rubber seals in muddy and dusty harsh working conditions.
• Eccentric lock collar delivers uniform circumferential clamping force, stable anti-slip under heavy continuous vibration, no scratches on shaft surface, suitable for constant single-direction rotation.
• High-rigidity integrated V cast iron housing, compact vertical wall mounting layout, small footprint, easy installation and disassembly, saves equipment installation space.
• ±2.5° self-aligning spherical outer ring eliminates extra internal stress caused by shaft deflection and assembly offset, reduces abnormal bearing wear and running noise.
• Reserved side grease fitting enables periodic supplementary lubrication, extends service life and cuts maintenance downtime.
• Fully heat-treated GCr15 bearing steel with stable heavy radial load capacity.
• Standard 50mm bore & 90mm outer dimension, fully interchangeable with single-seal LEU210 units for direct heavy-duty sealing upgrade.

Lower maintenance frequency and guarantee long-term stable operation of heavy-duty equipment

3. Applications
