Characteristics of structure and performance of NSK bearings

　　1 angular contact thrust ball bearings, NSK bearings
　　Thrust angular contact ball bearings contact angles of 60 ° angular contact thrust ball bearings are commonly used in General for double direction angular contact thrust ball bearings, mainly for precision machine tool spindles, general use with double row cylindrical roller bearings, can accommodate bidirectional axial loads, with high accuracy, good rigidity, low temperature rise, high speed, easy for setting or teardown, and other advantages.
　　2 deep groove ball bearings, NSK bearings
　　Structure of deep groove ball bearings on each ring has a cross section in the order of the Equatorial circumference of the ball one-third continuous Groove Raceway. Deep groove ball bearings are mainly used to accommodate radial loads, can accommodate some axial loads. When the radial clearance of bearings increases, has the nature of angular contact ball bearings, which can bear the alternating axial loads in both directions. Compared with other types of bearing of the same size, the friction coefficient of bearings of small, extreme high speed, high precision, is preferred by the user selection of bearing type. Deep groove ball bearing structure is simple, easy to use, is the production of bulk's largest, the most widely used class of NSK bearings.
　　3 thrust tapered roller bearings, NSK bearings
　　Because of thrust tapered roller bearings in rolling to the cone roller, rolling bus in structure and washer Raceway bus sinks intersect at a point on the axis of the bearing, thus rolling surface forming, speed limit higher than pure rolling cylindrical roller thrust bearings. Features: tapered roller thrust bearing may withstand the unidirectional axial loading. Code of thrust tapered roller bearing for 90,000.
　　4, double row tapered roller bearings NSK bearing structures, performance characteristics
　　Structure of double row tapered roller bearing range, a great deal of 35,000, have a dual Raceway in the outer ring and two rings, one intermediate ring between the two inner rings, change the thickness of the spacer of adjust clearance. These bearings while withstanding radial load can be subjected to bidirectional axial loads, axial internal clearance in the bearing within the limited axial displacements of the shaft and housing. Structural characteristics of tapered roller bearings. Tapered roller bearing type codes for 30,000, tapered roller bearings are separable bearings. Tapered roller bearings are mainly used to accommodate radial loads in the radial and axial combined loading. Compare with angular contact ball bearings, bearing capacity, low limit speed. Tapered roller bearings can accommodate axial loads in one direction, to limit the axial displacement of the shaft or shell in one direction.
