Decoding NSK 22312EAKE4
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- EAKE4Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22312 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 22312EAKE4 measures 60 mm across the bore and 130 mm across the outside diameter; its width is 46 mm (60 x 130 x 46 mm).

NSK spherical roller bearings handle radial and axial loads in both directions and can accommodate angular misalignment between shaft and housing. Their two rows of rollers running on a spherical outer raceway let the bearing compensate for deflection, which simplifies assembly tolerances. Typical uses include industrial transmissions, mining, cement and material handling equipment. MR Industrial Accessories LLC supplies this line to customers across the United States, Canada, Mexico and South America.
The EAKE designation breaks down as follows: the leading number gives the size, EA refers to a roller and cage design built for higher load capacity, K means a tapered bore with 1:12 taper, and E covers internal execution variants. A trailing 4 marks an NSK-specific modification. Reading the code this way helps you order the right replacement the first time.
These bearings show up in conveyor belts, mills, crushers, vibrating screens, speed reducers and process equipment in cement, mining, steel and food plants, as well as in large agricultural machinery and industrial fans. Because they tolerate misalignment, they suit long shafts or shafts on structures that deflect under load, where a rigid bearing would demand costly precision alignment.
Selection depends on radial and axial load, rotation speed and lubrication type. A bearing with the K suffix mounts on an adapter sleeve or a tapered shaft; either way, check internal clearance after adjustment. Open, shielded and sealed versions are available, and sealed variants are the choice where dust or moisture is present. Follow the manufacturer's recommendation for grease or oil and renew it according to service hours.
When cross-referencing other brands, spherical roller bearings are identified by their numeric designation plus suffixes for taper, cage and execution. Suffixes are not always interchangeable between manufacturers, so verify main dimensions and internal clearance before substituting. If you provide another brand's part number, we can point you to the equivalent NSK reference. Dimensional interchange is usually possible, but load capacities and limiting speeds may differ.

Frequently asked questions
- NSK 22312EAKE4 bearing: what are its dimensions?
- NSK 22312EAKE4 measures 60 mm across the bore and 130 mm across the outside diameter; its width is 46 mm (60 x 130 x 46 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22312.
- What does the K suffix mean in a spherical roller bearing?
- K indicates a tapered bore with 1:12 taper. This lets the bearing be mounted on an adapter sleeve or directly on a tapered shaft, which makes it easier to adjust internal clearance and to disassemble. It is often chosen where manufacturing tolerances need to be compensated.
- How do I choose between an open and a sealed bearing?
- It depends on the working environment. Where dust, moisture or particles are present, a sealed bearing protects the lubricant and keeps contamination out. In clean environments with oil lubrication, an open bearing can be used. Permissible speed also matters, since seals generate more friction and limit rpm.
- Can I replace a bearing from another brand with an NSK one?
- Generally yes, if the main dimensions and execution type match. Suffixes may vary between manufacturers, so check taper, cage and internal clearance. Send us the original brand's part number and we will tell you the equivalent NSK reference and the technical differences to consider.
