Description
Cylindrical Roller Bearing
Cylindrical Roller Bearings have high radial load carrying capacity and are suitable for high speeds. The bearings are separable which facilitates mounting and dismounting. Manufactured to precision tolerance class for demanding applications. Robust steel cage construction ensures durability. Suitable for use in a wide range of industrial applications where reliability and performance are essential.
Key Features
- High radial load capacity
- High load carrying capacity
- Open design for flexibility
- Robust steel cage construction
- Wide temperature range operation
- Precision tolerance class

How to Read an NSK Bearing Number
Every NSK bearing part number is built from a prefix (optional — load rating or special feature), a basic number (bearing type, dimension series, and bore size), and one or more suffixes (seals, clearance, cage, grease, and other features). Multiply the last two digits of the basic number by 5 to get the bore diameter in millimeters. Special bore codes: 00 = 10mm, 01 = 12mm, 02 = 15mm, 03 = 17mm.
