LYU 208 2F Vertical V-Type Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Seals

LYU 208 2F integrated vertical V-base grey cast iron bearing unit matched with YEL208-2F eccentric lock insert bearing. Double-sided 2F composite seal adopts metal centrifugal flinger + NBR rubber lip two-stage protection. Eccentric locking collar fixes extended inner ring for stable one-way rotation. Spherical outer ring achieves ±2.5° self-alignment to offset shaft assembly deviation. Dual-layer seal effectively blocks thick mud, crop dust, fine powder and water splashes. Side grease nipple allows regular relubrication, widely applied to heavy rotary tillers, large grain sorting machines, heavy-duty conveyors, textile and packaging machinery.

• Dual 2F anti-pollution seal: Metal flinger throws away thick mud by centrifugal force; inner rubber lip blocks fine dust and moisture, much better than single 2S rubber seals in muddy working sites.
• Eccentric lock collar provides uniform circumferential clamping, anti-slip under heavy continuous vibration without scratching shaft surface.
• Rigid compact V cast iron housing, small vertical wall mounting footprint, easy installation and disassembly, save limited equipment space.
• ±2.5° self-aligning spherical outer ring eliminates extra stress caused by shaft deflection and assembly offset, reduce abnormal bearing wear and running noise.
• Reserved grease fitting supports periodic supplementary lubrication to extend service life and cut maintenance downtime.
• GCr15 fully heat-treated bearing steel owns stable heavy radial load capacity.
• Standard 40mm bore & 80mm outer size, fully interchangeable with single-seal LYU208 unit for direct heavy-duty sealing upgrade.
