Decoding SKF 232/670-2CS5K/CNHGEN
- 232Series
- Spherical roller bearings, 232 series. Series differ in outside diameter and width even when the bore is the same.
- /670Bore
- Bore: 670 mm.
- 2CS5K/CNHGENSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
232/670 is the standard ISO basic designation, which sets the bearing type, series and bore.

The SKF 232/670-2CS5K/CNHGEN is a double-row spherical roller bearing that self-aligns to handle both radial and axial loads while compensating for angular misalignment between shaft and housing. This makes it a practical choice for equipment where mounting errors or shaft deflection are present, and where a rigid bearing would wear out early.
The bearing's part number breaks down into distinct segments. The 232 series identifies the basic design. The bore diameter is 670 mm. The 2CS5 suffix denotes a double contact seal, built with a specific material and geometry to keep lubricant in and contaminants out. The K indicates a tapered bore, which allows mounting on a tapered shaft or with an adapter sleeve. Finally, CNHGEN is an SKF internal code that bundles requirements for internal clearance, heat treatment, and special tolerances for demanding conditions.
Typical industries using this type of bearing include cement, mining, steel, paper, and wind power. You will find them in ball mills, crushers, vibrating screens, rotary kilns, large centrifugal pumps, and industrial fans. They also appear in earthmoving machinery and oilseed processing equipment. Their ability to accommodate combined loads and misalignment suits long shafts or shafts that deflect under load, where more rigid bearings would fail prematurely.
When selecting this bearing, consider radial and axial loads, operating speed, lubrication method, and the environment. The 2CS5 seal works well in dusty or humid conditions, but check that the operating temperature is compatible. For a tapered shaft, mounting with an adapter sleeve simplifies setting internal clearance; a cylindrical shaft requires a proper interference fit. Initial alignment is less critical than with rigid bearings, but stay within the permissible misalignment limits. Lubrication can be grease or oil, depending on the application and speed range.
Spherical roller bearings from different manufacturers use their own nomenclature. Suffixes for seals, taper, and internal clearance can vary, so direct interchangeability requires checking main dimensions, tolerances, and load capacity. Matching mounting dimensions alone is not enough; internal clearance and heat treatment also affect performance. Send us the complete code and we will help you identify the right option.

Frequently asked questions
- SKF 232/670-2CS5K/CNHGEN bearing: what are its dimensions?
- SKF 232/670-2CS5K/CNHGEN measures 670 mm across the bore and 1220 mm across the outside diameter; its width is 438 mm (670 x 1220 x 438 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 232/670.
- What does the CNHGEN suffix mean on this SKF bearing?
- CNHGEN is an SKF internal code that groups specifications for internal clearance, tolerances, and heat treatment for severe applications. It is not a public standard, so consult the manufacturer or a specialist to understand its exact effect on your equipment.
- Can this bearing handle misalignment between shaft and housing?
- Yes, spherical roller bearings are self-aligning and compensate for small angular misalignments. The permissible value depends on the series and size; generally it is greater than for rigid bearings, but always check the data sheet to avoid exceeding the limits.
- How do I choose between a sealed and an open bearing?
- The 2CS5 seal protects against dust and moisture, making it suitable for contaminated environments. If the bearing operates in an oil lubrication system or needs heat dissipation, an open version may be better. Evaluate your application conditions and consult us to decide.
