Decoding NTN 33122UE1
- 331Series
- Tapered roller bearings, 331 series. Series differ in outside diameter and width even when the bore is the same.
- 22Bore
- Bore 110 mm (22 × 5).
- UE1Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
33122 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 33122UE1 measures 110 mm across the bore and 180 mm across the outside diameter; its total width is 56 mm (110 x 180 x 56 mm).

For shafts that carry radial and axial forces at the same time, NTN tapered roller bearings are a standard choice. The tapered cone and cup create a linear contact path that spreads the load across the rolling surfaces. Typical installations include gearboxes, wheel hubs, pumps, fans and conveying equipment in industries such as automotive, steel, cement and food processing.
Reading the part number helps you order the right piece. In a reference like 33122UE1, the digits define the size and capacity of the bearing, while the UE1 suffix marks a particular construction variant from NTN. When you send us the complete designation, we quote that exact reference.
Selection depends on several operating factors: the radial load, the axial load, the rotational speed and the environment around the bearing. Correct mounting calls for precise alignment and proper lubrication, with grease or oil chosen to suit the application. The sealing method should match the level of contamination present. Poor installation can shorten bearing life.
If you are replacing a part from another manufacturer, we can cross it to an NTN reference. Provide the original part number and we will identify the matching bearing. Interchangeability works when dimensions and load ratings align, but checking the technical data before installation is always recommended.

Frequently asked questions
- NTN 33122UE1 bearing: what are its dimensions?
- NTN 33122UE1 measures 110 mm across the bore and 180 mm across the outside diameter; its total width is 56 mm (110 x 180 x 56 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 33122.
- What does the UE1 suffix indicate on an NTN bearing?
- The UE1 suffix denotes a specific construction variant in the series. It may relate to cage design, tolerances or heat treatment. For the exact characteristics of your part number, ask us on WhatsApp.
- How can I find the equivalent of a bearing from another brand?
- Send us the complete part number of the original bearing on WhatsApp. We will provide the equivalent NTN reference and a quote. Interchangeability depends on matching dimensions and load capacity.
- Which lubrication is suitable for these bearings?
- The choice between grease and oil depends on speed, temperature and operating environment. For many industrial applications, a lithium grease works well. Contact us on WhatsApp for advice based on your equipment.
