Decoding NTN 22207EMKW33
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- EMKW33Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22207 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 22207EMKW33 measures 35 mm across the bore and 72 mm across the outside diameter; its width is 23 mm (35 x 72 x 23 mm).

When shafts deflect or alignment between housing and shaft is less than perfect, an NTN spherical roller bearing keeps the assembly running. This self-aligning design uses two rows of rollers and a spherical outer raceway, so it carries heavy radial loads along with axial loads in either direction. Cylindrical or tapered bores are available, along with different cage and sealing options.
Reading the code helps you order the right variant. Take 22205EMKW33: the 22205 block gives the size, E stands for higher-capacity rollers, M for a machined brass cage, K for a tapered bore, and W33 for the lubrication groove and holes in the outer ring. A leading asterisk marks a special execution. Suffix changes point to other cages, seals or shields, so check each character against your application.
These bearings show up in mining, cement, steel, pulp and paper, and food processing equipment. Typical examples include conveyor belts, mills, mixers, centrifugal pumps and industrial fans. Because they tolerate small angles between shaft and housing, they suit long shafts and assemblies where thermal growth or load deflection causes misalignment. They also handle vibration and moderate impact.
Selection starts with radial and axial load, speed, and the surrounding environment. Contaminated conditions call for sealed or shielded versions. A tapered bore (K) mounts on an adapter sleeve and lets you set internal clearance. Grease or oil lubrication must match speed and temperature. During mounting, align the bearing correctly from the start and avoid impacts that could dent rollers or raceways.
NTN spherical roller bearings interchange with other brands that use the same dimensional nomenclature, such as SKF, FAG, NSK or Timken. Tolerances and internal clearance can differ between manufacturers, so verify them. When replacing a bearing, compare suffixes to preserve sealing, cage and lubrication characteristics. MR Industrial Accessories can help you find the correct equivalent from the original code.

Frequently asked questions
- NTN 22207EMKW33 bearing: what are its dimensions?
- NTN 22207EMKW33 measures 35 mm across the bore and 72 mm across the outside diameter; its width is 23 mm (35 x 72 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22207.
- What does the K suffix mean on an NTN spherical roller bearing?
- K indicates a tapered bore with a 1:12 taper. It allows mounting on an adapter sleeve or a tapered shaft, which simplifies setting internal clearance and securing the bearing. This option is common where mounting precision matters.
- How do I decide between a brass cage and a steel cage?
- The machined brass cage (M) is stronger and suits high-speed or high-load running. A stamped steel cage is lighter and more economical for normal conditions. Base the choice on speed, load and the working environment.
- What advantages does a spherical roller bearing offer over a deep groove ball bearing?
- A spherical roller bearing carries higher radial and axial loads and permits angular misalignment between shaft and housing. A deep groove ball bearing does not tolerate misalignment and has lower load capacity. For long shafts or assemblies with deflection, the spherical roller bearing is the better fit.
