LSS 211 2F Double Set Screw Insert Bearing, Dual-Side 2F Mud-Proof Labyrinth

1. Product Overview

LSS 211 2F is heavy spherical outer insert bearing with standard short inner ring, dual symmetric set screws and bilateral 2F composite labyrinth seals. Two-stage 2F seal with rotating metal flinger and rubber lip blocks farm mud, straw waste and industrial dust. Spherical outer ring provides ±2.5° self-aligning performance to offset slight shaft deflection. Pre-filled with high-temperature heavy-duty grease and equipped with relubrication nipple, ideal for large harvesters, rotary tillers, outdoor heavy conveyors and construction rotary parts with narrow installation space.

2. Key Advantages

• 2F composite labyrinth seal intercepts large impurities via metal flinger first, effectively reducing rubber lip abrasion compared with ordinary 2RS seals
• 120° symmetric double set screws evenly lock inner ring to shaft, stable anti-slip under medium vibration and forward-reverse rotation
• Standard short inner ring saves axial space, perfect for equipment with limited mounting length
• Spherical outer ring automatically compensates assembly misalignment to avoid abnormal bearing stress
• Built-in grease port supports regular refilling to extend continuous running service life
• GCr15 bearing steel with full heat treatment delivers stable heavy radial load capacity
• Standard 55×100×55.6mm dimensions match all standard cast iron bearing housings for direct replacement

Helps reduce maintenance cost and improve machine performance
