63 Series Radial Ball Bearing Types

Single Row Radial Ball Bearing, Made of Chrome Steel, Pre-lubricated with grease

The suffix “2RS” signifies the bearing is sealed, with rubber, on both sides. The suffix “ZZ” signifies the bearing is shielded, with metal, on both sides. Generally speaking, shielded bearings are more practical in cleaner, high-speed applications, while the sealed bearings are more practical for applications of slower speeds and dirtier environments.


Common applications for radial ball bearings include food processing, food and beverage industry, photo processing, appliances, furniture industry, marine applications, chemical and electroplating industries, paint and dye, textile industries, automotive, motorcycles, pumps, fans, water treatment, pharmaceutical industry and many other industrial applications.
