Description
NTN 4T-323062FD belongs to tapered 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 4T-323062FD and any equivalents.
The NTN 4T-323062FD is a tapered roller bearing whose inner and outer rings carry tapered raceways, so radial and axial forces travel along the shaft axis. Because it handles thrust in a single direction, it normally works alongside a second bearing or inside a matched set, which is how gearboxes, transmission cases and continuously running process equipment keep their shafts located.
Reading the code takes a moment, but it tells you what you are holding. The 4T block at the front marks the NTN catalogue line for this unit type. What follows is the size and dimensional series, and the FD ending signals a particular internal design inside that family. So 4T-323062FD carries line, size and execution in one string. Should a code show up with no suffix, confirm which variant it is before you ask for a quote.
Typical duty is any shaft seeing combined load: gearbox and transmission housings, road and agricultural machinery drives, conveyor rollers, machine tool spindles, rolling mill stands, process pumps, mills and lifting gear. In nearly all of these the bearing is paired, since one tapered roller resists axial load in one direction only.
For selection, match the bore and width to the shaft and housing seats, then pick the suffix that fits the clearance and sealing the equipment calls for. Fit and alignment need to be controlled, because misalignment speeds up raceway wear. Use the lubricant specified for the operating temperature and speed, set the working clearance through the axial tightening of the assembly, and clean the seat before anything goes on.
Cross-referencing works by series number and standardized dimensions, not by brand name. A code from another maker, or a part with no markings, can be matched using bore, outer diameter, width and raceway angle. What matters for interchange is those dimensions plus a matching execution type.
Send the code or the size to MR Industrial Accessories by WhatsApp or email and the team will quote it. If you only have another brand's reference, they can point you to the equivalent and help you choose.

Frequently asked questions
- How can I tell which variant of an NTN tapered roller bearing I have?
- The string is built from a prefix, a size number and a suffix. The prefix points to the catalogue line, the suffix to the internal execution, as in 4T-323062FD. Send the full code through WhatsApp if anything is unclear and the exact variant will be quoted.
- Is it acceptable to run a tapered roller bearing on its own?
- Better not to. Axial load is taken in one direction only, so these bearings go in pairs or matched assemblies. Where the shaft is loaded both ways, add an opposing bearing or use a matched set.
- Which details do you need to quote an equivalent?
- The part code together with bore, outer diameter and width is enough to cross-reference. Without a number, send the measurements via WhatsApp and the compatible alternative will be identified.
