PRODUCT DETAILS :

Spherical roller bearings


Spherical roller bearings has high load capacity, are capable of taking high radial loads and axial loads in one direction, suitable to work in conditions with heavy loads and vibration loads, but no pure axial loads can be sustained. The axial displacement of shaft and housing are limited within the range of axial clearance, and has good aligning ability to compensate for coaxial errors that occurred during operation. The limiting speed is low.

Applications:Has a widely applications in papermaking machinery, speed reducer, railway vehicles, printing machinery, woodworking machinery, various types of industrial reducer.

Spherical roller bearings

Has the general features of spherical roller bearings, can adjust bearing radial clearance inching.




Single row tapered roller bearings composition

Single row tapered roller bearings, including the bearing outer ring, as well as bearing inner ring locking ring and cage. There is a corresponding annular stress groove in the middle of the outer wall of the bearing outer ring. There should be a plurality of annular locking grooves on the outer wall of the outer ring. The shape and size of the locking ring are adapted to the shape and size of the annular locking groove. Single row tapered roller bearing ring locking groove equipped with a locking ring. An annular cage guide groove is arranged on the annular surface of the inner wall of the outer ring and the corresponding position of the stress groove. Single row tapered roller bearing the utility model has the advantages of convenient assembly, large load carrying capacity, high ultimate speed, high reliability and long service life.



Single row tapered roller bearings structure

1. Single row tapered roller bearings outer ring without ribs N0000 type and the inner ring without ribs NU0000 type, these tapered roller bearings can withstand greater radial load, high speed limit, does not constrain the axial displacement of the shaft or housing, can not bear the axial load.

2. Single row tapered roller bearings, inner and outer ring are tapered roller NJ0000 type, NF0000 type bearings can be bound shaft or housing in one direction of axial displacement, and can accept a smaller one-way axial load. NU0000 + HJ0000 type, NJ0000 + HJ0000 type, NUP0000 type bearings, the axial clearance of the axial direction of the shaft in the area of the axial clearance of the bearings can be constrained, and can accept smaller two-way axial load.



N, NU type

Single row tapered roller bearing N-type outer wall without ribs, both sides of the inner wall ribs. It is possible to allow axial displacement of the shaft relative to the housing in both axial directions. NU-type bearing on both sides of the outer wall with ribs, the inner wall without ribs. It is also possible to allow axial displacement of the shaft relative to the housing in both axial directions. Therefore, this type of structure is suitable for use as a traveling-end bearing.

NJ, NF type

NJ single row tapered roller bearings on both sides of the outer ring ribs, the inner ring has a single side. Can withstand a certain amount of one-way axial load. Single row tapered roller bearings NF-type outer ring has a single side, the inner ring on both sides of the wall. Can also withstand a certain amount of one way axial load. Therefore, this type of structure is suitable for use as a one way axial locating bearing.



NUP, NFP type

Single row tapered roller bearings NUP-type are ribs on both sides of the outer ring, the inner ring with a (fixed) single rib, and the other side of the separable flat ring. Can withstand a certain amount of two-way axial load.

Single row tapered roller bearing NFP-type outer ring with (fixed) single rib, and the other side of the separable flat ring, the inner ring on both sides of the rib. Can also withstand a certain amount of two-way axial load. This type of structural bearings can limit the shaft relative to the bearing seat in both axial displacement. Therefore, suitable for use as a fixed end bearing.

NH (NJ + HJ) type

Single row tapered roller bearings NH type are NJ type bearings and HJ-type ramp rings after the combination of the structure. As the inner ring of the NUP type bearing is short and the flat retaining ring is not fixed, the use is inconvenient. However, the NH type bearing can utilize the width of the entire inner ring of the NJ type bearing to maintain a closer cooperation with the shaft. And NH-type bearings in the installation and removal more convenient.

Single row tapered roller bearings NH type can limit the shaft relative to the bearing seat in both axial displacement. Therefore, suitable for use as a fixed end bearing.



Tapered roller bearing radial clearance adjustment method:

Tapered Roller Bearing selection fast and easy automation type selection can provide, fixed load load on the composite radial load from the local ring raceway fixed ring exposed and sent to the appropriate shaft or bearing local. The characteristic of this load is that the radial load vector is relatively static and the ring is synthesized. Bear the load ring, you can use relatively loose.

Rotational load is a full complement tapered roller bearing ring acting on a radial load on a rotating drum in the circumferential direction. The various parts of the rotation, such as the rotating load, are caused by the radial load rotation of the combined vector phase loop . In the case of a rotating load ring which fits closely, under special circumstances, the load, if elected, is light or heavy at low rotational speeds, but only occasionally in rings, the bearing is made of hard material and the surface roughness is high, the rotating load bearing ring can also be used more loosely.

Third load swing load or non-directional load, load ring radial load synthesis direction is uncertain, which is characterized by the radial load ring synthesis ring raceway role in a certain area within the impact load, vibration, load, the direction of swing, the roller to bear a certain area, or the role of bearing load, the load value often changes. To bear the weight swing, outer ring and weeks, bearings, holes should be used in close cooperation.



Commonly used to adjust the radial clearance of full complement tapered roller bearings as follows:

1, the cylindrical and oval shaped bearing pad backlash, manual grinding or bearing surface can be adjusted after the shaving method.

2, on the cylindrical and oval bushings of the top clearance, can be used to study manual scraping or the situation allowed when the bearing surface adjustment methods.

3, the multi-wedge fixed bearing, in principle, does not allow repair and adjust the bearing pad and gap, the gap should be replaced when inappropriate new tile.

4, on the multi-wedge tilt bearing, does not allow the repair scratch tile, the gap should be replaced due to improper tile. For tile with adjustable thickness, adjust the tile weight by adding a stainless steel pad under the tile adjustment tile or by reducing the thickness of the tile. Pay attention to the multi-wedge tilting pad, the same thickness error between tiles should be less than 0.01mm.
