Zhejiang Waxing Electromechanical Co., Ltd is one of the most professional manufacturers and suppliers of nu220ecm single row cylindrical roller bearing in China. Welcome to buy high quality customized bearings made in China here from our factory. For price consultation, contact us.
NU220ECM is a single row cylindrical roller bearing with the core advantages of high radial load capacity, allowing axial movement, low friction, and long service life. It is specifically designed for the non positioning support end of heavy-duty high-speed rotating machinery.
Main benefits
1. Extremely high radial load capacity: The cylindrical roller line contact structure has a radial load capacity far exceeding that of deep groove ball bearings under the same size
2. Adaptation to thermal expansion: The NU type structure allows the shaft to float axially in both directions relative to the bearing seat, avoiding thermal expansion jamming and making it suitable as a floating end
3. Low friction and high efficiency: EC optimizes the contact between the roller profile and the edge, reduces edge stress, lowers heat generation, and extends lifespan
4. Easy disassembly and assembly: The inner ring and roller cage components can be separated for easy interference fit installation and maintenance
5. High speed stability: The brass retainer has high strength, good thermal conductivity, suitable for medium to high speed working conditions, and strong impact resistance
Typical usage scenarios
-Industrial machinery: large motors, reducers, rolling mills, paper making machinery, plastic extruders, rubber granulators
-Machine tool equipment: radial drilling machine, lathe spindle non positioning end, grinder drive shaft
-Special equipment: welding equipment, mesh belt furnace, flash drying machine, cleaning machinery, fatigue testing machine
-Industry sectors: Metallurgy, Cement, Chemical, Woodworking Machinery, Agricultural Machinery, and Laboratory Mixing Equipment
