DKFL 22213 KMB W33 Spherical Roller Bearing
The spherical roller bearing, also known as the Spherical Roller Bearing (SRB), is one of the most robust rolling bearings in the industry, specifically designed to handle extremely heavy radial loads and simultaneous axial loads. Its unique structure, featuring barrel-shaped rollers and a spherical outer raceway, allows it to compensate for shaft and housing misalignment to a significant degree.

Decoding the Designation: What Does 22213 KMB W33 Mean?
Understanding each section of this standardized code ensures precise specification for maintenance and engineering applications:
- 222: Identifies the standard double-row spherical roller bearing ISO dimensional series.
- 13: Bore code calculation ($13 \times 5 = 65\text{ mm}$ nominal bore diameter).
- K: Indicates a 1:12 tapered bore designed for mounting with an adapter sleeve (H-series).
- MB: Solid machined brass cage guided on the inner ring, offering superior tensile strength, shock resistance, and fatigue endurance over standard pressed-steel cages.
- W33: Specifies an annular lubrication groove and three oil discharge ports on the outer ring for targeted lubricant flow straight to the rolling elements.
Key Advantages of the DKFL 22213 Bearing with Brass Cage (MB)
- Superior Dynamic Self-Alignment: Compensates for shaft deflections or angular misalignments up to 1.5°–2° without edge loading.
- Vibration and Shock Resistance: The robust machined brass cage resists structural deformation and fatigue during sudden load surges and vibrating duties.
- Straightforward Clearance Adjustment via H313 Sleeve: The tapered bore enables precise adjustment of Radial Internal Clearance (RIC) using feeler gauges and controlled locknut torque.
- Optimized Relubrication Regime: The standard W33 feature allows fresh grease to reach critical contact zones directly without needing bearing disassembly.
Common Industrial Applications of 22213 KMB W33
Due to its standardized envelope dimensions and high dynamic load capacity, this model is deployed across a broad range of heavy machinery:
- Split plummer block housings: SN 513 / SNL 513 / SNG 513
- Conveyor drive drums and return idler assemblies in cement, mining, and steel plants
- Vibrating screens and feeders in aggregate processing and quarry lines
- Industrial blowers and heavy-duty ventilation fans operating at medium-to-high speeds
- Industrial gear drives, crushers, and material pulverizing machinery
