UEF207 2S Square 4-Bolt Flange Bearing Unit, Double 2S Reinforced Rubber Dustproof Seals

1. Product Overview

UEF 207 2S four-bolt square cast iron flange bearing unit, matched with UE207-2S double set screw insert bearing. Equipped with double-sided 2S thickened NBR double lip rubber contact seals and two symmetric M10 set screws on inner ring. Spherical outer ring provides ±2.5° self-alignment to compensate shaft installation offset. Dual-layer rubber barrier effectively blocks dust, light mud splashes, water vapor and debris. Pre-filled long-life high temperature grease, side grease nipple supports periodic re-lubrication. Widely used on heavy agricultural machinery, heavy-duty belt conveyors, packaging equipment, textile heavy transmission rollers.

2. Key Advantages

• Dual 2S double lip rubber seals form dual anti-pollution barrier, reduce grease leakage and extend bearing service cycle
• Two symmetric M10 set screws evenly lock inner ring, stable anti-slip under continuous heavy vibration, fit forward & reverse rotation
• HT200 cast iron square four-bolt flange housing, high structural rigidity, flat mounting structure, easy installation and disassembly
• Spherical outer ring automatically corrects shaft misalignment, eliminates extra internal stress, lowers operation wear and noise
• Side grease fitting supports regular supplementary lubrication for long-hour continuous running
• GCr15 fully heat-treated bearing steel, stable heavy radial load capacity, compact layout size
• Standard 35×72mm metric dimension, fully interchangeable with single-seal UEF207 bearing units for sealing upgrade

Lower maintenance frequency and stable operation of heavy-duty machinery
