LSU 205 2F Vertical V-Type Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Seals

1. Product Overview

LSU 205 2F integrated vertical V-shaped grey cast iron bearing unit, matched with YAR205-2F double set screw insert bearing with extended inner ring. Double-sided 2F composite seal adopts metal centrifugal flinger plus NBR rubber lip two-stage labyrinth barrier. Two symmetric M5 set screws lock inner ring for stable bidirectional forward & reverse rotation. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly deviation. Dual-layer sealing effectively blocks light mud, crop dust, fine powder and water splashes. Side grease nipple supports regular re-lubrication, widely used on mini rotary tillers, lawn equipment, small grain sorting machines, light belt conveyors and miniature textile machinery.

2. Key Advantages

• Dual 2F anti-pollution sealing structure: Metal flinger throws away heavy mud and large debris by centrifugal force; inner rubber lip isolates fine dust, moisture and splashing water, far superior to single 2S rubber seals in slightly muddy and dusty working conditions.
• Two symmetric M5 set screws distribute clamping force evenly, stable anti-slip under light 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 light-medium radial load bearing capacity.
• Standard 25mm bore and 52mm outer diameter, fully interchangeable with single-seal LSU205 units for direct heavy-duty sealing upgrade.

Lower maintenance frequency and ensure long-term stable operation of light-duty mini equipment

3. Applications

• Mini rotary tillers, lawn mowers, small grain drying & sorting equipment
• Light-duty belt conveyors, miniature packaging production lines
• Small textile looms, miniature food processing transmission assemblies

8. FAQ

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 small agricultural and light industrial machinery working in muddy sites.

Q2: What equipment is LSU 205 2F suitable for?

Small agricultural machines, light conveyors, miniature food and textile equipment requiring compact vertical V-base installation and bidirectional rotation.

Q3: Can LSU 205 2F directly replace ordinary single-seal LSU205?

Yes, all installation and dimension parameters are fully consistent for direct upgrade to heavy-duty mud-resistant version.
