Product Description

The U209 maintenance-free bearing is a robust sealed roller bearing designed for industrial applications requiring long-term reliability without lubrication. Featuring a 190mm outer diameter, this 190mm maintenance-free bearing integrates dual-lip sealing to prevent contamination and retain pre-packed grease, suitable for heavy-duty machinery in sectors like material handling, agriculture, and conveyor systems. The U209 sealed roller bearing operates within a temperature range of -30°C to +120°C and withstands radial loads up to 38kN, with a maximum rotational speed of 1800 RPM. Its maintenance-free design eliminates periodic regreasing, reducing downtime. Key advantages include corrosion resistance, extended service life, and vibration damping, though performance may degrade in extreme overload or high-temperature scenarios exceeding specifications. The sealed structure ensures compatibility with dusty or humid environments common in mining and food processing industries.
