NSK MFJT-1212 belongs to needle roller 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 MFJT-1212 and any equivalents.
When axial loads need to be handled in a space too short for a conventional thrust bearing, the NSK MFJT series is a common answer. Each unit combines a washer with a needle cage. MR Industrial Accessories supplies this series and can quote it from the part number you provide.
The MFJT code itself tells you the size. Take MFJT-812: the first pair of digits, 8, is the shaft diameter in millimeters, and the second pair, 12, is the outside diameter of the washer. The same logic applies across the line: MFJT-1012 gives shaft 10 mm and outside 12 mm; MFJT-1212 gives 12 mm and 12 mm; MFJT-1414 gives 14 mm and 14 mm; MFJT-1514 gives 15 mm and 14 mm; MFJT-1614 gives 16 mm and 14 mm; MFJT-1618 gives 16 mm and 18 mm; and MFJT-1814 gives 18 mm and 14 mm.
These bearings turn up in automotive, metalworking, textile and food processing equipment, usually where axial forces are present but radial room is scarce. Gearboxes, pumps, compressors, machine tools and lifting equipment are typical examples. The low section height is what makes them usable where a taller thrust bearing will not fit.
Selection comes down to four things: the axial load, the speed, the lubrication method and the space available. The washer and shaft contact surfaces should be ground and hard enough to resist wear, and the shaft and housing need to be aligned so the load is shared evenly. Grease or oil both work, as long as a lubricant film is maintained.
Interchange is possible between brands when bore, outside diameter, height and load capacity line up. If you are working from another manufacturer's code, send it over and we will identify the matching NSK reference.

Frequently asked questions
- How do I read an NSK MFJT part number?
- The letters identify the thrust needle roller unit, made up of a washer and a needle cage. The four digits that follow give the dimensions: the first two are the shaft diameter in millimeters and the last two are the washer outside diameter.
- What should I check before choosing a thrust needle roller bearing?
- Look at the axial load, the operating speed, the lubrication available and the mounting height. Make sure the contact surfaces are ground and properly aligned. If you are unsure, send us your equipment details and we will help you select.
- Can an NSK bearing replace one from another brand?
- Often yes, provided the bore, outside diameter, height and load capacity match. Send us the original part number and we will tell you the NSK equivalent.
