UC Insert Bearing Size Chart
UC Insert Bearings are reliable and versatile components designed for standard-duty applications in industrial and agricultural machinery. Featuring a wide inner ring and a secure set screw locking mechanism, these bearings ensure stability and easy installation. Crafted from durable 52100 high-carbon steel with precision Grade 16 balls, UC Insert Bearings provide smooth operation and long service life. Each bearing is pre-lubricated with Shell Alvania 2 grease and protected by a Buna Nitrile seal with a slinger to guard against contaminants. A stainless steel option is also available for enhanced corrosion resistance.
