  This tapered thrust bearing with cage is a split design, so the two washers and the roller and cage thrust assemblies can be easily mounted separately. The all-bolt screw bearings are held together by special locating parts. For ease of handling, the washers have threaded holes for lifting the bolts. See the following description.

   

  

   

  1. Small one-way tapered thrust bearings are used almost exclusively in the steering knuckle bearing configuration of commercial vehicles.

  This tapered thrust bearing has a full roller and is held in place by a thin steel plate cover. Most of these bearings are equipped with wear-resistant, oil-resistant nitrile butadiene rubber (NBR) friction seals. These bearings are lubricated for life with a multi-purpose grease and require no maintenance. Available in a variety of designs, the only difference is the design of the bearing housing collar and housing.

   

  The larger tapered spring bearing washers are manufactured differently; some tapered thrust bearing washers have the same coaxial and housing collar, while others have a different design of tapered thrust bearing washers.

  The same size and coaxial bearing seat gasket has tapered raceways and locating retaining edges. This design of tapered thrust bearing is usually used in applications that require large axial loads, such as drilling equipment turntables or crane hooks. This tapered thrust bearing has a cage positioned by two washers.

   

  Other designs of tapered thrust bearing shaft washers have tapered raceways and locating retainers, while the tapered thrust bearing housing ring is flat (flat). Thus, tapered thrust bearings of this design can accept a slight eccentricity of the shaft relative to the housing bore without adversely affecting the bearing performance. In addition to several sizes with full rollers, this tapered thrust bearing has a cage concentric with the rollers.

   

  2. Two-way tapered thrust bearing

  Bidirectional tapered thrust bearings are mainly used in multi-row cylindrical roller bearings for rolling mills. This kind of tapered thrust bearing with flat shaft washer is therefore more popular.

   

  

   

  Two-way tapered thrust bearing

  Tapered thrust bearings are able to withstand slight eccentricity of the shaft relative to the housing bore as well as slight variations in radial internal clearance used in radial tapered thrust bearings. The spacer sleeve is set between the two bearing housing races. The size of the spacer sleeve allows the rolling bearing housing cap screws to be fully tightened and the bearing does not require special spring adjustment.

  Shaft and housing collar Bidirectional tapered roller thrust bearings with tapered raceways. Bearings with flat housing rings generally have a high axial load carrying capacity and can be radially positioned to a certain extent on the shaft. If the bearing capacity of tapered thrust bearings is not sufficient in view of the required service life, double row tapered roller bearings with a larger contact angle design can be used, see "Double row tapered roller bearings".

  As two-way thrust tapered roller bearings usually loose fit in the rolling journal and rolling bearing seat, so most tapered thrust bearing seat ring has one or two positioning groove.

   

  3. Screw fixing tapered bearings - thrust tapered roller bearings

  This type of tapered thrust bearing must be able to withstand extreme axial loads and allow angular displacement of the threaded shaft relative to the support. Therefore, these bearings are usually full roller types with large diameters and extra long rollers. In order to withstand the centering offset of the rolling bearing housing without affecting the bearing performance, tapered thrust bearings have a spherical seat ring. The seat ring can be a seat ring or bearing seat ring.

  The necessary centering offset occurs in bearings with a spherical collar on a roller set between the spherical collar and the corresponding concave spherical threaded shaft or pressure retainer. We can also provide the above-mentioned pressure stops.

  When the bearing housing ring is spherical, the centering offset is absorbed by the roller group between the bearing housing ring and the pressure retainer. This type of bearing pressure retainer is usually equipped with a tapered thrust bearing.
