Decoding NTN 22206EMW33
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- EMW33Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For equipment where shaft deflection or imperfect mounting is a fact of life, an NTN spherical roller bearing is a practical choice. Its two rows of rollers run in a self-aligning housing, so the bearing handles heavy radial loads plus axial loads in either direction. MR Industrial Accessories supplies this NTN line to maintenance and purchasing teams across the United States and Latin America, and can help you match the right execution to your application.
The part number tells you what you are getting. Take 22205EMW33: 222 is the medium-width spherical roller series, 05 is the bore size, E indicates a higher-capacity design, M is a machined brass cage, and W33 means the outer ring has a lubrication groove and holes. The same pattern appears in 22206EMW33 and 22207EMW33, only the size changes. Reading those suffixes correctly is the fastest way to avoid ordering the wrong variant.
You will find these bearings in cement, mining, steel, paper and material handling operations. Conveyors, mills, crushers, screens, industrial fans, cranes and process equipment all rely on them where loads are heavy and alignment is not perfect. The self-aligning design takes up shaft deflection and mounting error, which helps the whole assembly last longer.
Selection comes down to radial and axial load, speed, lubrication method and the environment. Choose the M brass cage for high temperatures and moderate speeds; W33 makes relubrication easier. When mounting, set the initial alignment and use a fit that lets the outer ring oscillate. Use the lubricant specified for the bearing and renew it on the service interval.
NTN spherical roller bearings interchange with other brands that share the same dimensional nomenclature, such as SKF, FAG or NSK. To replace a part safely, compare bore, outer diameter and width, then check the load conditions. MR Industrial Accessories helps you identify the correct equivalent so the replacement is reliable.

Frequently asked questions
- NTN 22206EMW33 bearing: what are its dimensions?
- NTN 22206EMW33 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 20 mm (30 x 62 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22206.
- What does the W33 suffix mean on an NTN bearing?
- W33 means the outer ring has a lubrication groove and three lubrication holes. That makes relubrication easier, particularly under high loads or moderate speeds.
- How do I check if a spherical roller bearing fits my equipment?
- Compare the bore, outer diameter and width, then review the load and speed conditions. If you have the original code, we can quote the NTN equivalent. Send it on WhatsApp or by email and we will advise.
- What is the advantage of a machined brass cage?
- A machined brass cage withstands temperature and dynamic stress better than stamped steel cages. It suits demanding applications with high loads or moderate speeds where durability matters.
