Decoding NSK 23156CAME4
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 56Bore
- Bore 280 mm (56 × 5).
- CAME4Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23156 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 23156CAME4 measures 280 mm across the bore and 460 mm across the outside diameter; its width is 146 mm (280 x 460 x 146 mm).

When shafts deflect or alignment is less than perfect, NSK spherical roller bearings keep equipment running. Their double-row design, with a spherical raceway in the outer ring, handles radial loads and axial loads in both directions while accommodating angular misalignment. Maintenance and purchasing teams specify them for conveyors, mills, pumps, fans and other heavy machinery. MR Industrial Accessories supplies the NSK brand and can help you confirm the right part number for your application.
The part number tells you more than size. In *21319CAME4 and *22228CAME4, the leading digits set the dimension series, while the CAME4 suffix points to a machined brass cage, center guide and special treatment. The same pattern appears in *22230CAME4 and *22232CAME4: base number for diameter and width, final letters for internal features such as cage type and clearance. Reading those suffixes correctly is how you avoid ordering a bearing that fits but does not match the original.
These bearings show up across cement, mining, steel, paper and food processing operations. You will find them in conveyor belts, ball mills, crushers, centrifugal pumps, industrial fans and paper machines. Misalignment capability matters most where vibration or shaft deflection is normal; in those conditions, a standard bearing can fail early. Pulp dryers and presses, as well as mining screens and mills, are common examples.
Selection starts with radial and axial load, speed and the environment. In dusty or humid areas, sealed or shielded variants are the practical choice. Lubrication also needs to match the duty: high-viscosity grease for elevated temperatures, or circulating oil in critical applications. During mounting, align the initial position and use a fit that still allows self-alignment; do not strike the rings. Keep internal clearance at the specified value so thermal expansion does not cause problems.
Cross-brand interchange is possible when dimensions and load capacity line up. An NSK bearing can be replaced by another brand with the same basic designation, but compare the suffixes because clearance, cage or heat treatment can differ. Send the complete part number, the size or a photo of the part via WhatsApp or email, and we will quote the exact replacement or suggest an equivalent.

Frequently asked questions
- NSK 23156CAME4 bearing: what are its dimensions?
- NSK 23156CAME4 measures 280 mm across the bore and 460 mm across the outside diameter; its width is 146 mm (280 x 460 x 146 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23156.
- What does CAME4 mean on an NSK spherical roller bearing?
- CAME4 identifies a design with a machined brass cage, center guide and special treatment. These letters affect lubrication and heat dissipation, so keep the suffix when ordering a replacement.
- How do I choose between a spherical roller bearing and a deep groove ball bearing?
- Spherical roller bearings handle misalignment and heavier loads, which suits flexible shafts or difficult mountings. Deep groove ball bearings are for moderate loads and precise alignment. If vibration or deflection is present, the spherical roller bearing is the better fit.
- Can I replace an NSK bearing with another brand?
- Yes, if dimensions and load capacity match. Check that the suffixes are equivalent, since they can change internal clearance or cage type. Send us the original part number and we will point out a compatible alternative.
