NTN tapered roller bearings are built to take radial and axial forces acting in a single direction. The tapered raceways and rollers create linear contact, which spreads the load across a wider area. This makes them a common choice for gearboxes, reducers, wheel hubs and other industrial equipment where forces come from more than one angle. MR Industrial Accessories LLC supplies these bearings as part of its bearing product line.
The part number on these bearings packs a lot of information. Take 4T-332/322DE: the 4T- prefix points to a tapered roller series, while 332 and 322DE are the cone and cup references. In 4T-331133DE and 4T-332072DE, the DE suffix marks a design variant, which can relate to contact angle or tolerance class. If you need help decoding a specific code, our technical team can walk you through it.
You will find these bearings in automotive, metallurgical, food processing and mining operations. They show up in gearboxes, drive shafts, conveyor rollers and earthmoving machinery. Because they tolerate combined loads, they suit equipment that sees variable forces and tough working conditions.
Choosing the right bearing starts with the radial and axial loads, the rotation speed and the operating environment. Proper mounting calls for accurate alignment and the right lubrication. In dirty or wet areas, consider seals or deflectors to keep contaminants out. Internal clearance matters too: set it wrong and you risk overheating or early wear. Stick to the manufacturer's mounting and lubrication guidelines.
NTN tapered roller bearings can be replaced with equivalents from other well-known brands when dimensions and load capacity line up. Check tolerances and internal design carefully, since small differences can change performance. If you have a part number from another brand, we can help you find the matching NTN reference.

Frequently asked questions
- What does the DE suffix mean in the designation?
- The DE suffix indicates a design variant within the series, which may refer to a specific contact angle or particular tolerances. To interpret the code correctly, consult us with the full reference.
- How can I tell if a bearing from another brand is compatible?
- Compatibility is determined by comparing main dimensions, load capacity and tolerances. If you send us the original brand part number, we will indicate the NTN equivalent.
- What lubrication do you recommend for these bearings?
- Lubrication depends on speed, temperature and environment. For standard applications, lithium grease is usually used; under extreme conditions, oil or special greases. Follow the manufacturer's instructions.
