LYS 209 2F Eccentric Lock Insert Bearing, Double-Side 2F Mud-Proof Labyrinth Seals

1. Product Overview

LYS 209 2F is large-size spherical outer insert bearing with bilateral 2F composite labyrinth seal and eccentric locking collar, interchangeable with YEL209-2F standard series. The eccentric collar clamps the whole shaft evenly to stop slipping under heavy vibration and impact loads. The 2F dual-layer seal combines metal flinger and rubber lip to block farm mud, crop straw and industrial dust. Pre-filled with heavy-duty high-temp grease and fitted with relubrication nipple, it matches large combine harvesters, rotary tillers, mine heavy conveyors and construction rotary equipment.

2. Key Advantages

• 2F dual labyrinth seal removes large mud debris via rotating metal flinger, reducing rubber lip wear vs standard 2RS seals
• Eccentric locking collar delivers full-circle shaft clamping, better anti-slip performance than double set screws under frequent forward-reverse rotation
• Spherical outer ring offers ±2.5° self-aligning ability to fix minor shaft installation deflection and avoid abnormal bearing stress
• Built-in grease nipple supports regular refilling to extend continuous heavy-load service life
• GCr15 bearing steel with full heat treatment provides stable heavy radial load capacity
• Standard 45×85×60.4mm dimensions fit all standard cast iron bearing housings for direct replacement

Helps reduce maintenance cost and improve machine performance
