The SKF WS series cylindrical roller thrust bearing is a high-capacity component for pure axial loads. It is used in applications where significant thrust must be supported in a small space, such as gearboxes, machine tool spindles and lifting equipment. At MR Accesorios Industriales we supply this series with SKF quality, backed by more than 80 years of experience in the industrial sector.
The WS series designation is interpreted as follows: the letters WS identify the shaft washer of a cylindrical roller thrust bearing. The numbers that follow, as in WS 81102, WS 81104 or WS 81120, indicate the size and dimensional series. For example, WS 81102 corresponds to a washer for a bearing of the 811 series, with a shaft diameter of 15 mm. Suffixes, if they appear, may indicate variants in surface treatment or tolerances, but in this series they are not specified in the listing.
These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in speed reducers, rotary tables, presses and material handling equipment. Their ability to support high axial loads makes them suitable for applications where axial space is limited and high rigidity is required, such as in milling machine or drilling machine spindles.
To correctly select a cylindrical roller thrust bearing, it is essential to consider the axial load, the rotational speed and the environmental conditions. Mounting must ensure precise alignment between the shaft washer and the housing washer, since these bearings do not compensate for misalignment. Proper lubrication, whether with grease or oil, extends service life. Sealing will depend on the contamination present; in dirty environments additional protection is recommended.
Regarding equivalences and interchangeability, SKF bearings of the WS series can be replaced by products from other manufacturers that follow the same standardized dimensions. It is important to verify the complete part number and tolerances, since small differences can affect performance. Always consult a specialist before replacing a component, especially in critical applications.

Frequently Asked Questions
- What does the WS designation mean in a thrust bearing?
- WS identifies the shaft washer of a cylindrical roller thrust bearing. The numbers that follow indicate the dimensional series and size, as in WS 81102. This washer is combined with the housing washer and the roller assembly to form the complete bearing.
- Where are cylindrical roller thrust bearings used?
- They are used in applications with high axial loads and limited space, such as reducers, machine tool spindles, rotary tables and lifting equipment. In Argentina, they are common in the metallurgical, cement and mining industries.
- How is a cylindrical roller thrust bearing mounted?
- Mounting requires precise alignment between the shaft washer and the housing washer, since they do not compensate for misalignment. It must be properly lubricated and sealing considered if there is contamination. Follow the manufacturer's instructions and consult a specialist if in doubt.
