Decoding NTN 22222EAD1
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 22Bore
- Bore 110 mm (22 × 5).
- EAD1Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22222 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 22222EAD1 measures 110 mm across the bore and 200 mm across the outside diameter; its width is 53 mm (110 x 200 x 53 mm).

NTN spherical roller bearings are built for applications that combine heavy radial loads with axial forces in either direction, and where shaft-to-housing alignment is not always precise. The two rows of rollers running on a spherical outer raceway let the bearing adjust to angular misalignment, so mounting tolerances can be less strict. You will find them in industrial drives, mining equipment and other heavy machinery where shaft deflection is a normal condition.
Reading the part number helps you pick the right variant. Take *22208EAD1: the asterisk means the base number changes with size, 222 is the medium-section spherical roller series, and 08 is the bore diameter code. The EAD1 suffix covers internal design details such as cage type and surface treatment. In *22308EAD1, the 223 series is wider and suited to higher load capacities. Understanding these codes makes selection faster and more accurate.
Typical uses include gearboxes, conveyors, mills, screens and crushing equipment in cement, mining, steel and aggregate processing, where loads are heavy and alignment is often less than ideal. The self-aligning design works well on long shafts that deflect and in mountings where supports cannot be perfectly aligned.
When selecting a bearing, consider radial and axial load, rotation speed and the working environment. Sealing matters: in dusty or humid conditions, choose variants with seals or flingers. Lubrication must match temperature and speed; high-viscosity grease is often used. During mounting, check initial alignment and avoid impacts that could damage rollers or raceway. Cage type and internal clearance also influence performance.
For equivalents, NTN spherical roller bearings can be interchanged with other brands that follow the same international nomenclature for series and suffixes. Always verify dimensions and tolerances before substituting one bearing for another, because small internal design differences can affect performance. If you are unsure, send us the original part number and we will help you choose.

Frequently asked questions
- NTN 22222EAD1 bearing: what are its dimensions?
- NTN 22222EAD1 measures 110 mm across the bore and 200 mm across the outside diameter; its width is 53 mm (110 x 200 x 53 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22222.
- What does the EAD1 suffix mean on an NTN bearing?
- EAD1 indicates specific internal design characteristics, including cage type, surface treatment of components and internal clearance. These variants are optimized for high loads and demanding lubrication conditions.
- How do I choose between the 222 and 223 series?
- The 222 series has a medium section, while the 223 is wider and offers higher load capacity. The choice depends on available space and on the radial and axial loads the bearing must withstand in your application.
- Does this bearing allow misalignment?
- Yes, spherical roller bearings compensate for angular misalignment between shaft and housing thanks to their spherical outer raceway and two rows of rollers. This simplifies mounting and reduces precision requirements.
