LSV 205 2F Vertical Plummer Block Bearing Unit, Double 2F Flinger-Rubber Anti-Mud Composite Seals

1. Product Overview

LSV 205 2F integrated vertical plummer block bearing unit, matched with YAR205-2F extended inner ring insert bearing. It adopts bilateral 2F composite sealing system: centrifugal metal flinger + inner NBR rubber contact lip seal, two symmetric M6 set screws lock the extended inner ring. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly misalignment. Double-layer 2F sealing effectively blocks thick farm mud, crop straw residues, industrial dust and water splashes. Built-in grease nipple supports periodic relubrication, widely used on grain harvesters, rotary tillers, grain sorting lines, light belt conveyors, food processing and textile machinery.

2. Key Advantages

• Dual 2F two-stage anti-contamination seal: Metal flinger throws away large mud/debris by centrifugal force; inner rubber lip seals fine dust and moisture, far better durability than single 2S rubber seals in muddy farm scenarios.
• 120° symmetric double set screws evenly clamp the extended inner ring, stable anti-slip performance under continuous medium vibration and forward-reverse rotation.
• Integrated vertical cast iron housing with high structural rigidity, compact vertical mounting layout, simple installation and disassembly.
• Spherical outer ring ±2.5° self-aligning design eliminates extra internal stress caused by shaft deflection and assembly offset.
• Reserved grease fitting allows regular supplementary lubrication to extend continuous heavy-load service life.
• GCr15 bearing steel with full quenching & tempering heat treatment, stable radial load bearing capacity.
• Standard 25mm bore & 52mm outer dimension, fully interchangeable with ordinary single-seal LSV205 bearing units for direct upgrade.
