Decoding NSK 22228CDE4
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 28Bore
- Bore 140 mm (28 × 5).
- CDE4Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22228 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 22228CDE4 measures 140 mm across the bore and 250 mm across the outside diameter; its width is 68 mm (140 x 250 x 68 mm).

NSK spherical roller bearings handle radial and axial loads in both directions. Their double-row design with a spherical outer raceway lets the inner ring and rollers self-align, so they tolerate angular misalignment between shaft and housing. You will find them in equipment where shaft deflection or mounting errors are a fact of life. MR Industrial Accessories LLC supplies these bearings and can help you match the right code to your application.
The part number tells you a lot. Take 22230CDE4: 222 is the dimension series, 30 is the bore in tens of millimeters, CDE covers the cage and roller design, and E4 indicates a treatment or lubrication groove. In 23024CDE4, 230 is a different section series. These codes let you find the exact reference in a catalog and order the correct replacement.
These bearings show up in mining, cement, steel, paper and aggregate processing, as well as gearboxes, conveyors, mills and road machinery. That is where loads are heavy and alignment is never perfect. The self-aligning feature helps reduce wear and extend service life in dusty, vibrating or shock-loaded environments.
Selection depends on radial and axial load, speed and lubrication type. Sealing matters: in contaminated areas, go with sealed or shielded variants. During mounting, check initial alignment and use the right tools to avoid damaging the rollers. Follow the manufacturer's lubrication spec and renew it according to your maintenance plan.
Cross-brand equivalences are common: an NSK code can be cross-referenced with other makers that use the same dimensional nomenclature. If you have a code from another brand or an unidentified part, send us the data and we will point you to a compatible alternative. MR Industrial Accessories LLC quotes the exact code or size you need.

Frequently asked questions
- NSK 22228CDE4 bearing: what are its dimensions?
- NSK 22228CDE4 measures 140 mm across the bore and 250 mm across the outside diameter; its width is 68 mm (140 x 250 x 68 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22228.
- What does the CDE4 suffix mean on these NSK bearings?
- CDE indicates a specific cage and roller design; E4 refers to a construction variant such as lubrication grooves. Suffixes can vary between series. Contact us on WhatsApp to interpret your exact code.
- How do I choose between the 222 and 230 series?
- The 222 series generally has a more robust section and higher load capacity, while the 230 is more slender. The choice depends on available space and loads. Send us your equipment dimensions and we will guide you.
- What should I consider for mounting?
- Check shaft and housing alignment, use suitable mounting tools and apply the recommended lubrication. Avoid direct blows on the rollers. If you need assistance, contact us.
