UEU 210 2S Vertical Insert Bearing, Double 2S Reinforced Rubber Seals, Dual M10 Set Screw Lock

UEU 210 2S spherical outer ring vertical insert bearing, matched with standard vertical cast iron housings. Equipped with double-sided 2S reinforced NBR rubber contact seals and two symmetric M10 set screws on extended inner ring. Spherical outer ring delivers ±2.5° self-alignment to compensate shaft installation misalignment. Dual-layer rubber barrier effectively blocks heavy dust, mud splashes, crop residues and splash water. Pre-filled high-temperature long-life grease, side grease nipple supports periodic re-lubrication. Widely used on heavy farm rotary tillers, large grain harvesters, mining heavy conveyors, textile and heavy packaging machinery.
