1. Product Overview

UEU 204 2S spherical vertical insert bearing matches vertical cast iron housings, equipped with double-sided 2S reinforced rubber contact seals and two symmetric M4 set screws on 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.
