Double row tapered roller bearings from NTN handle radial and axial loads in both directions, providing high load capacity and rigidity. They suit gearboxes, machine tool spindles and mining equipment, where precision and durability matter. We quote these bearings by part number or dimensions to match your application.
The part numbering for this series pairs a base number with the UTG suffix. In the 3230 UTG range you will find designations such as 323036UTG, 323038UTG and 323040UTG. The leading digits point to the size, while the trailing letters denote execution details. UTG marks a particular variant in NTN's double row tapered roller family, typically chosen for specific mounting needs or controlled internal clearance. Always check the manufacturer's tables to read each code correctly.
These bearings appear in metallurgy, cement, mining and machine tool operations. Typical installations include speed reducers, main spindles, rolling mill rolls and earthmoving equipment. Their design supports combined loads and maintains rigidity, making them a fit for mountings that demand precision and durability under tough conditions.
Selection depends on load magnitude and direction, rotation speed and the surrounding environment. Sealing plays a key role in keeping lubricant in and contaminants out; in dirty settings, add extra protection. Set internal clearance to match the mounting, follow the manufacturer's lubrication instructions, and ensure correct shaft alignment to avoid added stresses and extend service life.
When sourcing replacements, cross-brand equivalences exist, but confirm dimensions and load ratings. NTN's tapered roller range is broad, and we can help you find a compatible option. If you have a code from another maker, we can identify the NTN equivalent or a suitable alternative from another manufacturer.

Frequently asked questions
- What does the UTG suffix indicate?
- UTG denotes a specific variant within NTN's double row tapered roller line. It often relates to execution features such as cage type, internal clearance or heat treatment. Contact us for precise details.
- How do I decide between double row and single row?
- It comes down to the loads and rigidity required. Double row bearings take axial loads in both directions and offer higher load capacity, while single row types are used when loads are mainly radial or act in one direction. Assess your application.
- Can I replace a bearing from another brand with an NTN one?
- Often you can find an NTN equivalent that matches dimensions and capacities. Verify the technical specifications. Give us the original part code and we will help you identify the right option.
