The NTN 811 series cylindrical roller thrust bearing is a component designed to withstand high axial loads in one direction. Its construction with cylindrical rollers and washers allows high load capacities and axial rigidity. It is used in applications where precision and durability are critical, such as gearboxes, machine tool spindles and lifting equipment. MR Accesorios Industriales sells this series with the technical backing of more than 80 years in the Argentine market.
The 811 series designation is interpreted by its base number: the first digits indicate the type of cylindrical roller thrust bearing and the following ones the size. The usual suffixes, such as WS, identify the shaft washer, which in these mountings is usually supplied separately. For example, WS81100 corresponds to the shaft washer for bearing 81100. Knowing this nomenclature makes it easier to select the correct component according to the available space and the load to be supported.
These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in presses, extruders, cranes and earthmoving equipment. Their ability to withstand pure axial loads makes them ideal for applications where axial space is limited and high rigidity is required. They are also found in gearboxes and milling machine spindles, where axial precision is essential for surface finish.
To select the right bearing, it is crucial to consider the axial load, the rotation speed and the environmental conditions. The mounting must ensure precise alignment between the shaft and the housing; any misalignment reduces service life. Lubrication can be grease or oil, depending on speed and temperature. In applications with contaminants, additional seals should be evaluated. The WS washer must be mounted with the correct fit to prevent slipping.
NTN cylindrical roller thrust bearings are interchangeable with those of other brands that follow the same dimension standard. When replacing a bearing, it is important to check the critical dimensions: shaft diameter, outer diameter and height. The NTN 811 series is usually equivalent to similar series from other manufacturers, but compatibility must always be confirmed. MR Accesorios Industriales can advise you on the correct equivalent according to the original part number.

Frequently Asked Questions
- What does the WS suffix mean in a thrust bearing?
- The WS suffix identifies the shaft washer in cylindrical roller thrust bearings. This washer is mounted on the shaft and forms the raceway. It is important to select the washer corresponding to the bearing number to ensure the correct fit.
- How do I choose between a ball thrust bearing and a cylindrical roller thrust bearing?
- Cylindrical roller thrust bearings withstand much higher axial loads than ball thrust bearings, but they do not accept such high speeds. If the load is high and the speed moderate, the roller bearing is the option. For light loads and high speeds, the ball bearing is preferable.
- What lubrication do you recommend for these bearings?
- Lubrication depends on the working speed and temperature. For low speeds and high loads, high-viscosity grease is used. At high speeds, oil with a circulation system. It is essential to keep the lubricant clean and follow the manufacturer's instructions for each application.
