LSS 205 2F Spherical Outer Insert Ball Bearing with Dual 2F Composite Labyrinth Dust-Proof Seals

1. Product Overview

LSS 205 2F is a standard metric small-size insert ball bearing fitted with spherical outer ring and double-sided 2F composite labyrinth sealing system. Its extended dual-side inner ring adopts two M6 set screws to lock firmly on 25mm transmission shafts, while spherical outer surface delivers ±2.5° self-aligning capacity to compensate slight installation deflection. The exclusive 2F seal combines metal flinger labyrinth and rubber contact lip to block fine dust, crop debris and splashing water, factory pre-filled with long-life grease, widely used for small agricultural harvesters, light belt conveyors and mini food processing equipment.

2. Key Advantages

• 2F double composite labyrinth seal firstly blocks large debris via metal flinger, reducing rubber lip abrasion for long service life
• Spherical outer ring self-aligns automatically to offset minor shaft misalignment without extra mechanical stress
• Dual M6 set screws evenly lock inner ring onto shaft, avoiding slipping under continuous forward/reverse rotation
• Built-in relubrication grease nipple allows supplementary grease filling to extend running cycle
• GCr15 high carbon chromium bearing steel undergoes complete heat treatment for stable radial load capacity
• Standard 25×52×34.1mm dimensions fully interchangeable with UC205 series for all standard bearing housings

Helps reduce maintenance cost and improve machine performance
