Decoding NSK 22236CDKE4
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 36Bore
- Bore 180 mm (36 × 5).
- CDKE4Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22236 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 22236CDKE4 measures 180 mm across the bore and 320 mm across the outside diameter; its width is 86 mm (180 x 320 x 86 mm).

NSK spherical roller bearings are self-aligning units that use two rows of rollers running on a spherical outer raceway. They handle heavy radial loads plus axial loads in either direction, and they accommodate angular misalignment between shaft and housing. That makes them a practical choice for conveyors, mills, pumps, fans and other process equipment where shaft deflection or mounting inaccuracies are part of normal operation.
The CDKE4 suffix appears in this series alongside the basic size number. The basic number sets the size, while CDKE4 identifies a version with a stamped steel cage, a tapered bore and tolerances specific to the series. To read a code, separate the basic number from the suffix: 22230CDKE4 and 23024CDKE4 are two sizes in the same family. When the marking on the part is visible, send it exactly as stamped.
These bearings show up in equipment with long shafts or shafts that flex: belt conveyors, mills, mixers, centrifugal pumps, industrial fans and continuous process machinery. They also suit installations where the housing is not perfectly rigid or where support alignment is not exact. Because they are self-aligning, they absorb small mounting errors and misalignment without giving up load capacity.
Selection depends on radial and axial load, rotation speed and mounting style. The tapered bore allows mounting with an adapter sleeve or directly on a tapered shaft, which helps when adjusting internal clearance. Grease or oil lubrication can be used depending on the application; in dusty or humid conditions, consider additional seals or protection. Initial alignment and mounting clearance are critical—too much or too little clearance shortens service life. Follow the manufacturer's instructions for mounting and lubrication.
Spherical roller bearings are made to dimension and tolerance standards that allow interchangeability between brands. If the code you have belongs to another brand, we can identify the equivalent in the NSK line. If the part has no identification, main dimensions or a photo can guide us to the right replacement. Interchangeability is not always direct: check suffixes and special executions before replacing.

Frequently asked questions
- NSK 22236CDKE4 bearing: what are its dimensions?
- NSK 22236CDKE4 measures 180 mm across the bore and 320 mm across the outside diameter; its width is 86 mm (180 x 320 x 86 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22236.
- What does the CDKE4 suffix indicate on an NSK bearing?
- CDKE4 indicates a version with a stamped steel cage, a tapered bore and tolerances specific to the series. Combine the basic number (for example, 22230) with the suffix to read the full code. If unsure, send the marking exactly as it appears on the part and we will quote it.
- How can I check if a spherical roller bearing fits my equipment?
- Verify the main dimensions (bore, outer diameter and width), the bore type (cylindrical or tapered) and the execution suffix. If the code is from another brand, we can identify the NSK equivalent. Send the details via WhatsApp or email and we will advise.
- Which lubricant should I use in a spherical roller bearing?
- The choice depends on speed, temperature and environment. Grease or oil are both possible. In dusty or humid conditions, evaluate additional seals or protection. Follow the manufacturer's recommendations for lubricant type and relubrication interval. If you need guidance, ask us.
