Product Details:

We provide NTN Cylindrical Roller Bearings are available with us in varied sizes and designs. Our professionalism and ethical standards have set a benchmark in the industry. These bearings are of high capacity and widely appreciated as multi-row bearing. High speed and quick accelerations are the prime factors of our NTN Cylindrical Roller Bearings owing to which these are widely demanded in the market. We are leading supplier, wholesaler, and importer of bearings in India and thus make sure to fulfill the client requirement within committed time frame.

Ideal for heavy radial load at moderate speed
High load bearing capacity
High speed capability
Rugged construction

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
