Ball Bearing, 1/2"X1-3/8"X7/16"

KML Ball Bearing, 1/2"X1-3/8"X7/16"

The 1621-2RS KML Ball Bearing is a precision deep-groove ball bearing designed for smooth rotation, durability, and long service life in mechanical equipment. Built with double rubber seals (2RS), this bearing helps keep premium Mobil Polyrex EM grease inside while preventing contaminants from entering, extending bearing life and maintaining consistent performance. Manufactured to ABEC-3 precision standards with grade-10 balls and finely honed raceways, it delivers reliable operation with reduced noise and vibration—because when machinery spins smoothly, everything else tends to run better too.
