Description
NTN K81120T2 belongs to cylindrical roller thrust bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for K81120T2 and any equivalents.
When you need a bearing that takes heavy thrust in a single direction, the NTN cylindrical roller thrust bearing is built for that job. Its cylindrical rollers give it high axial stiffness and load capacity, so it fits machinery where axial forces dominate. You will find it in industrial equipment, transmission systems and other setups that demand precision and reliable performance.
The part number tells you a lot. The 811 or 812 series identifies the cylindrical roller thrust type, and the T2 suffix means a high-strength polyamide cage. So K81100T2 is an 811 series bearing with a T2 cage. The numbers after the letters set the size and load capacity. Once you know this scheme, you can read a code quickly when you need to request a quote.
These bearings show up in metallurgy, cement, mining and materials handling. They are common in presses, extruders, cranes and lifting systems that have to take considerable axial thrust. You will also find them in gearboxes and machine tool spindles. Because they handle unidirectional loads, they suit applications where precision and durability matter.
Selecting the right one means looking at the axial load, rotation speed and the environment. Sealing and lubrication are critical: in dirty conditions, add extra protection. Mounting must be aligned precisely to avoid parasitic stresses. The T2 cage resists temperature and chemicals well, but check that it is compatible with your lubricant.
For equivalences, NTN cylindrical roller thrust bearings can be interchanged with other brands that use the same dimensional designation. Still, verify tolerances and cage type, since these can differ between manufacturers. To be safe, consult a specialist and provide the complete code of the original part.

Frequently asked questions
- What does the T2 suffix mean in an NTN thrust bearing?
- The T2 suffix indicates a high-strength polyamide cage. This cage guides the rollers and reduces friction between them, and it handles moderate temperatures well.
- How do I choose between the 811 and 812 series?
- It depends on the axial load and the space available. For the same bore diameter, the 812 series usually has a higher load capacity than the 811. We can advise based on your application and housing dimensions.
- What should I consider for mounting?
- Make sure the raceways are correctly aligned and avoid impacts that could damage the rollers. Use adequate lubrication, and add sealing if the environment is contaminated. Follow the manufacturer's recommendations.
