Cylindrical Roller Bearings

Cylindrical roller bearings (CRBs) are used in countless industrial applications, such as reduction gears for robots or rail machineries, gear motors for fixed machineries, gearboxes for mobile equipments and speed multipliers for wind turbines. Designed to support high radial loads, they can also withstand axial loads if they feature shoulders on their inner and outer rings.

Two categories are available:  

• With a cage: high accelerations, high rotation speeds and high radial loads
• Without a cage: the maximum quantity of rollers is used, and the supported loads are higher than CRBs with cages, however the rotation speed will be moderate

Focus on our range of cylindrical roller bearings:

Bearing types: 

• Row: NU, NJ, NUP, N, NF, NH, NJV, NFV
• Rows: NNU, NN, SL
• Rows: 4R

Dimensions: bore diameter from 20mm to 1250 mm for the standard range and beyond for tailor-made range

Why choose an NTN cylindrical roller bearing 

• Premium brands: our cylindrical roller bearings are defined according the ultimate design rules and offer best-in class quality level.
• Standard or tailor-made ranges: with just over 1,500 product references, our standard CRB range fulfils all your needs, while the bearings under ULTAGE label provide the highest level of performance and reliability. Our tailor-made range will meet all your specific needs. 
• Optimized cages made of polyamide, steel or brass: depending on their properties (mechanical resistance, elasticity, high temperature resistance, speed ability), the cages improve the performance of cylindrical roller bearings.
