NTN bearing have deep groove ball bearings, thrust angle contact ball bearings, thrust tapered roller bearings, double row circular cone roller bearings, they have their respective structure and performance characteristics.

NTN deep groove ball bearing

On the structure of deep groove ball bearings with each of the contractor are cross section for the ball about a third of the perimeter of the continuous groove type groove. Deep groove ball bearings are used to bear radial load, also can withstand the axial load. This bearing has the following features:

When bearing radial clearance increases, has the nature of the angle contact ball bearing and can withstand two alternating direction of the axial load;

And the same size as the other types, deep groove ball bearing small friction coefficient, extreme high speed, high precision, when the user is the preferred bearing type selection;

Deep groove ball bearing structure is simple, easy to use, is the production batch is the largest, most extensive application of a class of NTN bearing.

NTN thrust angle contact ball bearing

This bearing contact Angle for 60 ° commonly. Commonly used thrust Angle contact ball bearing general for two-way thrust Angle contact ball bearing, mainly used for precision machine tool spindle. This bearing has the following features:

General and double row cylindrical roller bearing used together, it can be subject to bi-directional load;

With high precision, good rigidity, low temperature, high speed, installation convenience etc.

NTN thrust taper roller bearings

The thrust of the tapered roller bearings rolling body for tapered roller, on the structure of the bus and gasket rolling rolling way are in the HuiJiao bus bearing a point axis line, rolling surface can form pure rolling, limit rotational speed higher than cylindrical roller thrust bearing.

This bearing has the following characteristics: thrust taper roller bearings can withstand one-way axial load. Thrust tapered roller bearing type code 90000 type.

NTN double row circular cone roller bearings

Double row circular cone roller bearings structure is various, the maximum amount of 35000 type, have a double groove outer ring and two inner circle, two inner circle a circle between isolation, change the circle of the thickness can be adjusted clearance. This type of bearings in bear radial load at the same time it can be subject to bi-directional load, can be in bearing axial clearance range limit axis and the shell of the axial displacement. This bearing has the following characteristics of:

Tapered roller bearing type code 30000, tapered roller bearings for separating type bearings;

Mainly used for bear in radial direction load primarily radial and axial combined load;

Compared with Angle contact ball bearing, carrying capacity, low limit speed;

 
To withstand a direction of the axial load, can limit shaft or housing a direction of the axial displacement.
