LES 210 2F Double Set Screw Insert Bearing, Bilateral 2F Mud-Proof Labyrinth Seals

1. Product Overview

LES 210 2F is large spherical outer insert bearing with dual-sided 2F composite labyrinth seals and symmetric double set screws. The two-stage 2F seal consists of metal flinger and rubber lip to block mud, crop straw and industrial dust. Spherical outer ring offers self-aligning performance to compensate slight shaft misalignment. Pre-filled with high temperature heavy-duty grease and equipped with relubrication nipple, widely applied on grain harvesters, rotary tillers, outdoor heavy conveyors and construction rotary equipment.

2. Key Advantages

• 2F composite labyrinth seal intercepts large impurities via rotating metal flinger, effectively reducing rubber lip abrasion compared with ordinary 2RS seals
• Dual symmetric set screws evenly lock inner ring onto shaft, stable anti-slip under medium vibration and frequent forward-reverse rotation
• Spherical outer ring provides ±2.5° self-aligning ability to avoid abnormal bearing stress caused by assembly deflection
• Reserved grease nipple supports regular supplementary lubrication to extend continuous operation service life
• GCr15 bearing steel with full heat treatment ensures stable heavy radial load capacity
• Standard 50×90×51.6mm dimensions fit all standard cast iron bearing housings for direct replacement

Helps reduce maintenance cost and improve machine performance
