Description
NSK FNTA-1730 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 FNTA-1730 and any equivalents.
The NSK FNTA series needle thrust bearing handles axial loads within a very small height. It is a caged needle assembly that runs directly between two raceway surfaces, so it suits spots where thrust ball or roller bearings will not fit. Common uses include gearboxes, clutches and steering mechanisms.
The part number tells you the size. FNTA-1024 is for a 10 mm shaft with a 24 mm outside diameter, FNTA-1226 for a 12 mm shaft and 26 mm outside diameter, and FNTA-2035 for a 20 mm shaft and 35 mm outside diameter. The first digits give the shaft diameter and the last digits the outside diameter, so you can identify a size without a catalog.
Because there are no washers in the assembly, the shaft and housing faces act as the raceways. They must be ground, hardened and within the right roughness for the bearing to work as intended. Lubrication should be generous, using oil or grease suited to the operating conditions. During mounting, keep the shaft and housing aligned and center the needle cage without interference to avoid eccentric loads.
These bearings are found in automotive, metalworking and agricultural machinery, including manual transmissions, clutch systems, hydraulic pumps and lifting equipment. They are also used at low speeds with moderate to high axial loads, as long as the contact surfaces meet the hardness and finish requirements.
If you are replacing another brand, compare shaft, outside and height dimensions and check the load capacity, since similar designations can differ between makers. MR Industrial Accessories LLC supplies the NSK FNTA series to customers across the United States and in several Latin American countries. Send the part number or your dimensions by WhatsApp or email and the team will quote promptly, suggest equivalents and help with selection, lubrication and mounting.

Frequently asked questions
- What does the designation FNTA-1226 mean?
- FNTA identifies the series. The first two digits, 12, are the shaft diameter in millimeters; the last two, 26, are the outside diameter. So an FNTA-1226 fits a 12 mm shaft and a 26 mm housing bore.
- Does this bearing include raceway washers?
- No. The FNTA bearing is a cage with needles and no washers. The shaft and housing surfaces serve as the raceways and must be ground and hardened. If you need washers, ask by WhatsApp or email and we will point you to the right option.
- How do I request a quote for an FNTA bearing?
- Send the full part number, such as FNTA-1629, or the shaft and outside dimensions you need via WhatsApp or email. We will quote promptly and can advise on lubrication and mounting.
