Single row cylindrical roller thrust bearing, single directionSingle row cylindrical roller thrust bearings are designed to accommodate heavy axial loads and peak loads in one direction, but not radial loads. They provide a high degree of stiffness and require little axial space. They are mainly used in applications where thrust ball bearings do not have sufficient load carrying capacity. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
- High axial load carrying capacity
- High stiffness
- Long service life
- Require little axial space
- Separable design
