UYU 204 2S Vertical Insert Bearing, Double 2S Rubber Seals, Eccentric Lock Collar

UYU 204 2S spherical vertical insert bearing fits vertical cast iron housings, equipped with double-sided 2S reinforced 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 rubber barrier seals block fine dust, mud splashes, water and crop debris effectively. Pre-filled long-life high-temperature grease with side grease nipple for periodic relubrication, widely applied to small agricultural equipment, mini conveyors, textile looms and light packaging machinery.
