Decoding NTN 32212U3EC
- 322Series
- Tapered roller bearings, 322 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- U3ECSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 32212U3EC measures 60 mm across the bore and 110 mm across the outside diameter; its total width is 29.75 mm (60 x 110 x 29.75 mm).

NTN tapered roller bearings are engineered to manage combined radial and axial loads through the angled positioning of their rollers and raceway geometry. They suit gearboxes, wheel hubs, spindles, and power transmission equipment where high load capacity and rigidity are required. MR Industrial Accessories LLC supplies this line to customers throughout the United States and Latin America.
The part number system follows NTN nomenclature. Basic numbers such as 32212, 32213, 32214, 32216, or 32217 denote the size and dimensional series. The U3 suffix covers contact angle and manufacturing precision. EC indicates an internal design with a stamped steel cage and guided rollers. Reading these codes correctly helps you match the bearing to the application.
Typical uses include gearboxes and reducers, wheel hubs on industrial vehicles, road machinery, mining equipment, mills, and conveyors. The combination of radial and axial load capacity makes these bearings a common choice where precision and durability matter.
Selection depends on the radial and axial loads, operating speed, and environmental conditions. Proper mounting requires careful alignment and adequate lubrication, since tapered rollers are sensitive to installation errors. Sealing and internal clearance also affect performance and service life.
NTN tapered roller bearings can be interchanged with those from other recognized brands when dimensions and tolerances match. For replacements, verify the complete code and technical specifications. Our team can help with code equivalence and selecting the right option for your equipment.
