- 34Bore
- 170 mm bore: 34 × 5.
- CDE4Suffix
- NSK suffix: it defines the variant (sealing, cage, internal clearance or other features).
22234 is the standard (ISO) basic designation: it defines the type, the series and the bore.

NSK spherical roller bearings are double-row self-aligning components designed to support high radial loads and axial loads in both directions. Their spherical outer raceway allows the inner ring and rollers to self-align, compensating for angular misalignment between shaft and housing. They are used in applications where shaft deflection or mounting errors require tolerance. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the correct code for your equipment.
The series designation combines numbers and letters that identify the size and variants. For example, in 22230CDE4, the 222 indicates the dimension series, 30 the bore diameter (in tens of millimeters), CDE the cage and roller design, and E4 the treatment or lubrication groove. In 23024CDE4, the 230 corresponds to another section series. These codes allow you to locate the exact reference in the catalog and request the appropriate replacement.
In Argentine industry, these bearings are used in mining, cement, steel, paper and aggregate processing equipment. They also appear in gearboxes, conveyors, mills and road machinery, where loads are high and alignment conditions are never perfect. Their self-aligning capability reduces wear and extends service life in environments with dust, vibration or shock.
To select correctly, take into account the radial and axial load, the rotational speed and the type of lubrication. Sealing is key: in contaminated environments, choose variants with seals or protective plates. During mounting, verify the initial alignment and use suitable tools to avoid damaging the rollers. Lubrication must be as specified by the manufacturer and renewed according to the maintenance plan.
Equivalences between brands are common: an NSK code can be cross-referenced with references from other firms that follow the same dimensional nomenclature. If you have the code from another brand or an unidentified part, send us the data and we will indicate the compatible alternative. At MR Accesorios Industriales we quote the exact code or size you need.
To proceed with your inquiry, send us the complete code or the main dimensions via WhatsApp: bore, outer diameter and width. With that data, we will quote promptly and advise you on the best option for your application.

- The NSK 22234CDE4 bearing has a 170 mm bore, a 310 mm outside diameter and a 86 mm width (170 x 310 x 86 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 22234.
- What does the designation CDE4 mean in these NSK bearings?
- The letters CDE indicate a specific cage and roller design, while E4 refers to a construction variant, such as lubrication grooves. These suffixes can change between series. To interpret your exact code, contact us on WhatsApp.
- How do I choose between the 222 and 230 series?
- The 222 series usually 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?
- Verify 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.
