LYU 204 2F Vertical V-Type Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Seals

1. Product Overview

LYU 204 2F integrated vertical V-base grey cast iron bearing unit matched with YEL204-2F 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 light mud, crop dust, fine powder and water splashes. Side grease nipple allows regular relubrication, widely applied to mini rotary tillers, lawn equipment, small grain sorting machines, light conveyors and miniature textile machinery.

2. Key Advantages

• Dual 2F anti-pollution seal: Metal flinger throws away thick mud by centrifugal force; inner rubber lip isolates tiny dust and moisture, much better than single 2S rubber seals in muddy working sites.
• Eccentric lock collar provides uniform circumferential clamping, anti-slip under light 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 light-medium radial load capacity.
• Standard 20mm bore & 47mm outer size, fully interchangeable with single-seal LYU204 unit for direct heavy-duty sealing upgrade.

Reduce maintenance frequency and improve long-term stable running of mini equipment
