NFB cylindrical roller bearing are available in many designs, series and sizes. The majority are single row bearings with a cage.
Highcapacity bearings, single and double row full complement bearings (without a cage) complete the europe standard assortment.
Bearings with a cage can accommodate heavy radial loads, fast accelerations and high speeds.
Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. NFB high capacity cylindrical roller bearings combine the high load carrying capacity of a
full complement bearing with the high speed capability of a bearing with a cage. There are N, NU, NJ, NF, NUP series for single row. For single row full complement, there are NCF, NJG, SL. For double rows.
there are NN, NNU, NNJ,NNF,NNUP,NNCL, NNCF,NNC,SL.
. The roller and roller race is line contact and large radial capacity which help to bear heavy loading and punching loading.
. Due to small friction, it suit for high speed operation machine. The limit speed is near to deep groove ball bearings.
. N, NU type of bearing is movable in axial direction which can accept a certain position change between the bearing and bearing shell because of heat swell expanding or installation tolerance.
.There is a high standard requirment for finishing bearing or bearing shell hole. After installing the bearing, require to control strictly
the axial center line, avoiding strength focusing on one part.
The outer race or inner race is able to separate which make it convenient to install and dismantle.
Application of cylindrical roller bearing
Large and medium electric motor and Locomotive vehicle and Machine tool spindle, Internal-combustion engine,
Generator, Gas turbine engine, Reduction box, Rolling mill, Vibration sieve and crane and transporting machinery.
