1. Product Overview

LSS 208 2F is a standard metric insert ball bearing built with spherical outer ring and dual-sided 2F composite labyrinth sealing system. Its extended double-side inner ring matches standard bearing housings, while the spherical outer surface delivers self-aligning capacity to compensate slight shaft installation deflection. The exclusive 2F seal combines metal flinger labyrinth and rubber contact lip to block coarse dust, mud and splashing water, factory pre-filled with long-service grease, widely applied on farm equipment, belt conveyors and light processing machinery exposed to harsh particle pollution.

2. Key Advantages

• Dual-layer 2F labyrinth composite seal resists coarse dust, mud and moisture far better than ordinary 2RS single lip seals
• Spherical outer ring realizes ±2~3° self-alignment, offsets minor shaft misalignment and housing assembly errors
• Extended two-side inner ring enables stable shaft locking via set screw or eccentric collar accessories
• Relubrication port reserved for supplementary grease filling to extend service cycle under continuous operation
• GCr15 bearing steel with precision heat treatment offers stable radial load capacity for medium heavy-duty rotation
• Universal ISO 40mm bore dimension fits all standard UCP, UCF, UCFL series bearing housings for direct replacement

Helps reduce maintenance cost and improve machine performance
