- 16Bore
- Bore 80 mm (16 × 5).
- U3EESuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
33216 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

NTN tapered roller bearings handle radial and axial forces at the same time. The angled rollers and raceways spread the load, which suits machinery where alignment and fit matter. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in several Latin American countries.
The series code tells you what you are holding. Take 33212U3EE: 332 is the series, U3 marks a special execution, and EE identifies the sealing or cage variant. The same pattern applies to 33213U3EE, 33214U3EE, 33215U3EE, 33216U3EE and 33217U3EE, where only the numeric block changes with size. If any of these suffixes are unclear for your application, send the reference over WhatsApp and we will go through it with you.
You will find these bearings in conveyors, gearboxes, transmission shafts and process equipment across food processing, metallurgy, mining and agriculture. Their tapered layout works well where axial clearance has to stay under control and running needs to remain smooth under demanding conditions.
When selecting a bearing, look at the radial and axial loads, the rotation speed and the environment. The EE seal keeps contamination out, while the U3 suffix can point to a specific internal clearance. During mounting, check shaft alignment, apply the right lubricant, and pay attention to axial retention and preload adjustment.
Interchange with other recognized brands is possible when the main dimensions and execution type match. Compare suffixes as well as the numeric code, because they define sealing or internal clearance. Our technical team can help you confirm a compatible part.
