Description
NSK TRC-411 belongs to needle 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 TRC-411 and any equivalents.
When a shaft has to carry thrust but there is almost no room around it, the NSK TRC series needle thrust bearing is one of the options maintenance teams reach for. The assembly is built around a needle cage that runs between two raceway faces, usually thrust washers. Gearboxes, clutches and steering mechanisms are typical homes for it, because mounting height is tight there and the axial load still has to be handled.
Reading the code is the first step. The letters TRC stay fixed and the figures behind them point to a size within the series, as in TRC-411, TRC-613 or TRC-1427. Those figures are not a diameter you can measure with a caliper; they are an internal reference tied to the dimensions of the complete assembly. The reliable way to confirm a size is the manufacturer's table or the technical data sheet, and we quote against the exact code you send us.
You will run into these bearings in automotive work, machine tools, lifting equipment and power transmission drives. Gearboxes, pumps, compressors and clutch systems are common places to find them. Because the section is so low, they fit where a conventional thrust bearing simply will not go, and they take load in one direction while keeping the assembly rigid.
Selection comes down to three things: the axial load to be carried, the speed of rotation and the space available. Just as important are the surfaces the needles roll on, which need the right hardness and finish. Lubrication has to be adequate, otherwise wear sets in early. At assembly, check alignment and keep impacts away from the cage and the needles.
Needle thrust bearings built to the same dimension standard can be swapped between brands. If the code you have comes from another maker, we can cross it to the equivalent. The low profile is what sets the TRC series apart, but the critical dimensions should always be confirmed before a replacement goes in.
Send the code or the measurements you need on WhatsApp or by email and our team will come back with a quote. Where a direct match is not available, we can point you to a compatible alternative, and we are glad to help with assembly and lubrication questions for your application.

Frequently asked questions
- What does the TRC designation mean in needle thrust bearings?
- TRC identifies the NSK needle thrust bearing series, and the figures that follow, such as in TRC-411, point to the size of the assembly. They are not a direct diameter but a reference taken from the tables. Send us your code on WhatsApp and we will quote it.
- Where are TRC series needle thrust bearings used?
- They suit applications that combine axial load with very little radial room, including gearboxes, clutches, steering mechanisms and machine tools. Automotive work and industrial equipment are the sectors where they show up most often.
- How do I choose the right TRC needle thrust bearing?
- Look at the axial load, the rotation speed and the mounting space. The raceway surfaces must be suitable and lubrication must be correct. If anything is unclear, send your inquiry on WhatsApp and we will help you sort it out.
