Features of Single-row cylindrical roller bearings NTN N series (contains model NJ311ET2X)

Cylindrical roller bearings can accommodate heavy radial loads due to the line contact formed between their rolling elements and raceways. These bearings are also suitable for high speed applications since the rollers are guided by either inner or outer ring ribs. Cylindrical roller bearings are separable, allowing them to be easily installed and disassembled even when interference fits are required.
Application: pumps/ air compressors/ industrial rolling machines/ precision machining machines
