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

1. Product Overview

LSS 206 2F is a medium metric insert ball bearing with spherical outer ring and dual-sided 2F multi-stage labyrinth sealing system. It features dual M6 set screws on extended double-side inner ring to lock shafts stably under forward and reverse rotation cycles. The exclusive 2F sealing assembly combines metal anti-impurity flinger and NBR rubber lip, which intercepts crop dust, mud and workshop abrasive particles effectively. Pre-filled with long-service grease and reserved relubrication ports, this bearing fits medium-duty agricultural rotary machines, industrial belt conveyors and outdoor processing equipment exposed to severe particle pollution.

2. Key Advantages

• 2F multi-layer composite labyrinth seal blocks coarse debris by metal flinger first, greatly reducing rubber lip wear compared with single-lip 2RS sealed bearings
• Spherical outer ring offers ±2.5° self-aligning capacity to offset minor shaft deflection and housing assembly offset errors
• Dual symmetric M6 set screws evenly fasten inner ring to shaft, eliminating slipping risk under frequent forward-reverse operation
• Built-in grease nipple supports supplementary lubrication to extend continuous running service cycle
• GCr15 bearing steel undergoes standardized quenching and tempering for 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
