30232 DF Tapered Roller Bearing, 160x290x52.73mm

INTRODUCTION:

Taper roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

Taper roller bearing are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.

Taper roller bearing are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

Taper roller bearing mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring’s raceway. The bigger the contact angle is, the greater the capacity will be.

Taper roller bearing the angle between the outer raceway generatrix and line, the bearing can bearing heavy load and other Tappered Roller Bearings, it mainly bears joint load based on one way axial load,but not only radial load.

Taper roller bearings have tapered inner and outer ring raceways, The tapered roller is in the middle of the two raceways. This kind of bearings is usually separatable, namely the retainer, inner ring and outer ring can be installed apart. They can withstand immense radial direction load and certain axial load. They are designed in different sizes and styles to meet all kinds of functions.

Notes on the use of tapered roller bearings

1. For tapered roller bearings, if the bearing load is too small during operation, or the ratio of the axial load to the radial load of the paired duplex bearings exceeds the e value, the distance between the rollers and the raceways of the row that does not bear the axial load There will be slippage between them, which will cause minor scratches. This tendency is especially true for large tapered roller bearings, where the rollers and cage are heavy.

       If the above load conditions are expected, please contact NSK when selecting bearings.

2. When selecting HR series bearings, please confirm the installation-related dimensions such as Da, Db, Sa, and Sb.

limit speed

       Although the limit speed of the bearing is written in the bearing dimension table, the limit speed needs to be corrected according to the load conditions. In addition, the improvement of the lubrication method can also increase the limit speed

  Tapered roller bearings are mainly suitable for bearing combined radial and axial loads mainly based on radial loads, while tapered roller bearings with large taper angles can be used to bear combined radial and axial loads mainly based on axial loads. 

  This type of bearing is a separable bearing, the inner ring (including tapered rollers and cage) and the outer ring can be installed separately, the radial clearance and axial clearance of the bearing can be adjusted during installation and use, and can also be pre-set. Interference installation.

DF single row tapered roller bearing 30000 type

    This kind of bearing can limit the axial displacement of the shaft or housing in one direction and bear the axial load in one direction. Under the action of radial load, additional axial force will be generated. Therefore, generally in the two bearings of the shaft, the end faces of the outer ring and inner ring of the bearing with the same name are installed opposite each other. If used alone, the applied axial force must be greater than that of the additional shaft. Xiangli. 313 series tapered roller bearings have a large contact angle (27°-30°) and can withstand large axial loads. The contact angle of other series bearings is between 10°-18°.

    The ISO355 tapered roller bearing size series code is given in the single row tapered roller bearing size table, which is only for reference when bearings are interchanged.

    The size of the axial clearance of the tapered roller bearing has a great influence on whether the bearing can work well. When the axial clearance is too small, the temperature rises; when the axial clearance is too large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation.
