LSU 207 2F Vertical V-Type Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Seals

LSU 207 2F integrated vertical V-shaped grey cast iron bearing unit, matched with YAR207-2F double set screw insert bearing with extended inner ring. Bilateral 2F composite seal adopts centrifugal metal flinger plus NBR rubber lip two-stage labyrinth barrier structure. Two symmetric M7 set screws lock inner ring evenly to support stable bidirectional forward & reverse rotation. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly deviation. Dual-layer sealing effectively blocks thick mud, crop residues, industrial dust and splashing water. Side grease nipple supports regular re-lubrication, widely used on medium-heavy rotary tillers, grain sorting equipment, heavy-duty belt conveyors, packaging and textile machinery.

• Dual 2F anti-pollution sealing structure: 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.
• Two symmetric M7 set screws distribute clamping force evenly, stable anti-slip under medium-heavy continuous vibration, no shaft surface scratches, suitable for frequent forward-reverse operation.
• High-rigidity integrated V cast iron housing, compact vertical wall mounting layout, small occupation space, easy installation and disassembly.
• ±2.5° self-aligning spherical outer ring eliminates extra internal stress caused by shaft deflection and assembly offset, reduces abnormal wear and running noise of bearing.
• Reserved side grease fitting supports periodic supplementary lubrication, extends service life and cuts maintenance downtime.
• Fully heat-treated GCr15 bearing steel with stable medium-heavy radial load bearing capacity.
• Standard 35mm bore and 72mm outer diameter, fully interchangeable with single-seal LSU207 units for direct heavy-duty sealing upgrade.

1. Q1: What advantages does 2F double seal have over single 2S rubber seal?
   2F adopts two-stage composite protection: outer metal flinger first blocks thick mud and crop waste, inner rubber lip isolates tiny dust and water mist, specially developed for agricultural machinery working in muddy sites.
2. Q2: What equipment is LSU 207 2F suitable for?
   Medium-heavy agricultural machines, heavy conveyors, food and textile equipment requiring vertical V-base installation and bidirectional rotation.
3. Q3: Can LSU 207 2F directly replace ordinary single-seal LSU207?
   Yes, all installation and dimension parameters are fully consistent for direct upgrade to heavy-duty mud-resistant version.
