UYU 209 2S Vertical Insert Bearing, Double 2S Rubber Seals, Eccentric Lock Collar

UYU 209 2S spherical outer ring insert bearing matched with vertical cast iron housings, fitted with double-sided 2S reinforced NBR rubber contact seals and eccentric locking collar on extended inner ring. Spherical outer ring provides ±2.5° self-alignment to compensate shaft assembly offset. Dual-layer rubber barrier effectively blocks heavy dust, mud splashes, crop residues and splashing water. Pre-filled high-temperature long-life grease, side grease nipple allows periodic re-lubrication. Widely applied to heavy rotary tillers, grain harvesters, heavy-duty belt conveyors, textile looms and large packaging equipment.

• Dual 2S double lip rubber seals form double anti-pollution barrier, reduce grease leakage and extend bearing service cycle
• Eccentric lock collar provides uniform circumferential clamping force, stable anti-slip under heavy continuous vibration, fits one-way constant rotation
• Spherical outer ring eliminates extra internal stress caused by shaft installation misalignment, lower running wear and noise
• Reserved side grease fitting supports regular supplementary lubrication for long-hour non-stop heavy load operation
• Whole set GCr15 fully quenched bearing steel, excellent wear resistance and heavy radial load capacity
• Standard 45×85mm unified dimension, fully interchangeable with single-seal UYU209 insert bearings for direct upgrade
