LSU 210 2F Vertical V-Type Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Seals

1. Product Overview

LSU 210 2F integrated vertical V-shaped grey cast iron bearing unit, matched with YAR210-2F double set screw insert bearing with bilateral extended inner ring. Double-sided 2F composite seal adopts centrifugal metal flinger + NBR rubber lip two-stage labyrinth barrier structure. Two symmetric M10 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 heavy rotary tillers, large grain harvesters, heavy-duty belt conveyors, packaging and textile machinery.

2. Key Advantages

• 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 M10 set screws distribute clamping force evenly, stable anti-slip under 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 heavy radial load bearing capacity.
• Standard 50mm bore and 90mm outer diameter, fully interchangeable with single-seal LSU210 units for direct heavy-duty sealing upgrade.

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

3. Applications
