Pay attention to the scope of each NTN cylindrical roller thrust reference. This family combines rolling elements with surfaces receiving axial force, but a component code does not imply that a complete bearing is being requested. That distinction matters when replacing parts while other elements remain in the machine.

The catalog records WS81100, WS81101, GS81100 and GS81101 in this line. Preserve the initial letters; reducing the designation to its numeric series removes information needed to distinguish the part. Placement in the same category does not establish equivalence.
When an exploded drawing identifies separate components, maintain that separation in the enquiry. Match each inscription to its drawing position. Do not assume rollers, a cage or other parts are included merely because the page uses the bearing family name.
Begin by identifying how thrust reaches the assembly and which surfaces transfer it to the machine structure. Show the component sequence, shaft orientation and elements controlling axial position. Axial refers to load direction relative to the shaft rather than the physical orientation of the machine.
Keep parts from similar positions separately labelled. Mixing them can conceal which marking belongs to each seat. Contact marks and measurements document what was found, but are insufficient alone to reconstruct an unconfirmed arrangement.
Send MR the complete NTN references and quantity for each component. Include an exploded drawing or an ordered photograph, marking requested and retained parts. If a complete support assembly is required, state that explicitly so its composition can be checked before a partial list is treated as a complete enquiry.
Do not assume so. Identify the part and check the requested components against the equipment drawing.
No. Initial letters belong to the designation and distinguish catalog records.
Provide a drawing or ordered photographs showing the parts you have, and leave unidentified items explicitly unresolved.

The NTN cylindrical roller thrust bearing is a component designed to support 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.
The NTN GS811 series cylindrical roller thrust bearing is a component designed to withstand high axial loads in one direction. It consists of a shaft washer, a housing washer and a set of cylindrical rollers guided by a cage. It is used in applications where the main load is axial and high load capacity and rigidity are required, such as gearboxes, pumps, compressors and industrial equipment. MR Accesorios Industriales sells this series with personalized technical support.
The NTN cylindrical roller thrust bearing is a component designed to withstand high axial loads in one direction. Its design with cylindrical rollers and washers allows linear contact that provides high load capacity and axial rigidity. It is used in applications where the main load is axial and reliable performance is required, such as gearboxes, machine tools and lifting equipment. MR Accesorios Industriales sells this line.
