LES 206 2F Spherical Outer Insert Ball Bearing, Dual-Side 2F Flinger-Labyrinth Composite Seals

1. Product Overview

LES 206 2F is a medium-size metric insert ball bearing with spherical outer ring and dual-sided 2F multi-layer labyrinth sealing assembly. Equipped with double M6 set screws on extended dual-side inner ring, it delivers stable shaft locking for forward and reverse rotation. The exclusive 2F structure combines metal anti-dust flinger and NBR rubber lip seal to block crop debris, mud and industrial dust; factory pre-filled with long-life grease and reserved relubrication ports, perfectly matched to medium-duty agricultural machinery, belt conveyors and outdoor processing equipment exposed to particle pollution.

2. Key Advantages

• 2F double composite labyrinth seal first intercepts coarse impurities via metal flinger, drastically reducing rubber lip abrasion vs standard single-lip 2RS seals
• Spherical outer ring provides ±2.5° self-aligning capacity to compensate minor shaft deflection and housing assembly offset
• Dual M6 set screws evenly fasten inner ring onto shaft, preventing slipping under frequent forward-reverse rotation cycles
• Built-in grease nipple supports supplementary lubrication to extend continuous running service life
• GCr15 bearing steel with standardized heat treatment maintains stable medium radial load capacity
• Standard 30×62×38.1mm dimensions fully interchangeable with UC206 series for all standard cast iron bearing housings

Helps reduce maintenance cost and improve machine performance
