Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.
Separable design
The shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.
Low friction
The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.
Long service life
Depending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles.
Enhanced operational reliability
The surface finish on the contact surfaces on the rollers and raceways supports the formation of a hydrodynamic lubricant film.
Here are examples of applications in which tapered roller thrust bearings might be used:
- Material handling
- Industrial transmissions
- Machine tools
- Trucks, trailers and buses
Single row cylindrical roller bearings are available in many designs, series and sizes.
Double row cylindrical roller bearings are available in several designs with a cylindrical or tapered bore.
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses.

Single row angular contact ball bearings can accommodate axial loads in one direction only.
The design of the double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.
Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions.

Single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The assortment of matched single row tapered roller bearings is based on popular sizes of single row tapered roller bearings.
Double row tapered roller bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.

Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads.
Needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers.

Pillow block bearing units consist of an insert bearing mounted in a housing, which can be bolted to a support surface.
Flanged bearing units consist of an insert bearing mounted in a housing, which can be bolted to a machine wall or frame.
The take-up bearing unit assortment comprises of insert bearing series and designs, with the main differences between the take-up units being the housing design, the locking method onto the shaft, the sealing solution, and the options for end covers and back seals.
