NTN 4T series tapered roller bearings are designed with tapered raceways to handle combined radial and axial loads in one direction. The rollers, guided by the cone and cup, provide progressive linear contact, making them suitable for shafts with high axial demand. They are commonly found in reducers, wheel hubs, transmission cases and heavy-duty movement equipment. MR Industrial Accessories supplies these bearings to customers across the United States and in several Latin American countries.

The part number of a 4T series bearing is structured in blocks. The prefix 4T denotes the NTN tapered roller line. The basic number indicates the size and the cone-cup ratio. Suffixes show design variants. For example, in 4T-32008X3CD, the numeric block 32008 is the dimension series, the X means a modified cone or cup execution, and CD refers to the angle and machining of the assembly. When requesting a quote, provide the complete code as it appears on the part or drawing.

These bearings are used in speed reducers, gear cases, wheel hubs, rear axles, road machinery and lifting equipment. They also appear in milling lines, aggregate conveying, presses, process pumps and general industrial transmissions. Because they are separable, the cone and cup are mounted independently, which simplifies replacement where access is limited and the shaft is already in place.

Selection depends on the simultaneous radial and axial load, rotation speed and lubrication type. Proper mounting requires careful alignment and controlled axial adjustment: too much clearance causes noise and wear, while too little raises temperature. Before start-up, check seal condition, housing cleanliness and lubrication. On equipment subject to vibration, verify the cone seating on the shaft.

Interchange between brands is based on dimensions and code. A tapered bearing from another manufacturer can be replaced if bore diameter, outer diameter, width and contact angle match. The series number alone is not sufficient; the complete designation must be compared because suffixes affect machining and mounting. If you have the part in hand or a code from another brand, send us the data and we will identify the compatible alternative.

To request a quote for an NTN tapered roller bearing, contact us via WhatsApp with the exact code or dimensions. Our team will respond promptly and assist with selection to ensure the correct replacement. We also handle interchange inquiries when you have an unidentified part or a code from another brand.
