Decoding NTN 23956EMD1
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- 56Bore
- Bore 280 mm (56 × 5).
- EMD1Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23956 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

NTN spherical roller bearings with the EMD1 suffix cover a wide range of series and sizes, from 22208EMD1 to 23148EMD1 and 24064EMD1. All share a common design: two rows of rollers running on a spherical raceway in the outer ring. Because dimensions vary with each part number, a replacement requires the complete designation.
The spherical raceway in the outer ring lets these bearings accommodate shaft misalignment and deflection. They handle high radial loads and axial loads in both directions. This makes them suitable for equipment subject to shocks, vibrations, or where perfect alignment is difficult to maintain.
The part number combines a five-digit number with the EMD1 suffix. The first digits indicate the series: 22, 23, and 24 are different series, and within each series the size changes. The EMD1 suffix is part of the designation and must match exactly; dimensions depend on the specific part number.
Typical applications include vibrating screens, mills, conveyor belts, industrial fans, and gearboxes. In such demanding environments, an incorrectly identified replacement can lead to unplanned downtime. Confirming the part number before ordering is recommended.
During mounting, follow the manufacturer's fits for shaft and housing. If the fit is tight, heat the inner ring in a controlled manner, avoiding direct flame. Check clearance and lubrication, as these bearings operate under high loads. Clean, careful mounting directly affects service life.

Frequently asked questions
- NTN 23956EMD1 bearing: what are its dimensions?
- NTN 23956EMD1 measures 280 mm across the bore and 380 mm across the outside diameter; its width is 75 mm (280 x 380 x 75 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23956.
- What advantage does a spherical roller bearing offer?
- Its spherical raceway compensates for shaft misalignment and supports high radial and axial loads in both directions. It is used in applications with shocks or vibrations.
- Is the EMD1 suffix mandatory when ordering?
- Yes. It is part of the full designation and must be provided to identify the correct bearing.
- How can I confirm the part number of a used bearing?
- Read the number engraved on the ring. If it is worn off, measure the bore, outside diameter, and width, and send us the dimensions with a photo.
