The SKF WS series covers cylindrical roller thrust bearing shaft washers. These components handle pure axial loads and are common where thrust capacity is needed in a tight axial envelope, such as gearboxes, machine tool spindles and lifting equipment. MR Industrial Accessories LLC supplies this series to customers across the United States and Latin America.
Reading the code is straightforward. WS marks the shaft washer of a cylindrical roller thrust bearing. The digits that follow, as in WS 81102, WS 81104 or WS 81120, give the size and dimensional series. These washers pair with bearings of the 811 series across a range of shaft diameters. Any suffix that appears may point to a variant in surface treatment or tolerances.
Typical industries include metallurgy, cement, mining and machine tools. You will find these washers in speed reducers, rotary tables, presses and material handling equipment. Their role is to carry high axial loads where axial space is limited and rigidity matters, for example in milling or drilling spindles.
Selection depends on the axial load, the rotation speed and the operating environment. Mounting must align the shaft washer and the housing washer precisely, because these bearings do not compensate for misalignment. Grease or oil lubrication both work; correct lubrication supports service life. Sealing choices follow the contamination level, and dirty environments call for extra protection.
For interchangeability, SKF WS series washers can be replaced by products from other manufacturers that follow the same standardized dimensions. Check the complete code and tolerances, since small differences can affect performance. In critical applications, confirm the replacement with a specialist before installing it.

Frequently asked questions
- What does WS mean in a thrust bearing designation?
- 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. They are common in the metallurgical, cement and mining industries.
- How should a cylindrical roller thrust bearing be mounted?
- Mounting requires precise alignment between the shaft washer and the housing washer, since they do not compensate for misalignment. Lubricate properly and consider sealing if contamination is present. Follow the manufacturer's instructions and consult a specialist if in doubt.
