NTN deep groove ball bearings
In the structure of each ring of deep groove ball bearings are a cross-section about the equatorial circumference of the ball one-third of the continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, and can withstand a certain amount of axial load. This bearing has the following characteristics:
When the radial bearing clearance increases, with the nature of the angular contact ball bearing can withstand both directions alternating axial load;
Compared with the same size as other types of bearings, deep groove ball bearing small coefficient of friction, high limiting speed, high precision, user selection of the preferred bearing type;
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, the most widely used class of NTN bearings.
NTN thrust angular contact ball bearings
This bearing contact angle of 60 °. The common thrust angular contact ball bearings is generally a two-way thrust angular contact ball bearings for precision machine tool spindle. This bearing has the following characteristics:
Generally used in conjunction with the double row cylindrical roller bearings can accommodate axial loads;
With high precision, good rigidity, low temperature, high speed, easy assembly and disassembly.
NTN thrust tapered roller bearings
A rolling thrust tapered roller bearings tapered roller, rolling on the structure of the bus and washer raceway bus intersect at a point of the bearing axis line, the rolling surface can be formed of pure rolling, the speed limit higher than the thrust cylindrical roller bearings.
This bearing has the following features: thrust tapered roller bearings can withstand a one-way axial load. The thrust tapered roller bearing type code 90000.
NTN double row tapered roller bearings
The range of double row tapered roller bearing structure, the maximum amount of 35000-type, one pair of roller outer and two inner, a spacer between the two inner change of the thickness of the spacer to adjust the clearance. This type of bearing can bear radial load bi-directional axial load, axial displacement of shaft and housing bearing axial clearance within the limit. This bearing has the following characteristics:
The tapered roller bearing type code 30000, tapered roller bearings for the separation of bearings;
Mainly used to bear radial load mainly radial and axial loads;
Angular contact ball bearings compared to the carrying capacity, low speed limits;
Able to withstand a direction of axial load, and to limit the axial displacement of the shaft or housing in one direction.
