| Common Misspellings | 22217 EAKE4C3; 22217EAK E4 C3; 22217EAKE4G3; NSK 22217 EAK; 22217 EA KE4C3 |
| Application Types | Conveyor pulleys and head shafts; fans and blowers; crushers and screens; mill shafts; gearbox output shafts; any heavily loaded position with shaft deflection or misalignment |
| Bore Shaft Size | 85 mm TAPERED bore, 1:12 taper. Requires an adapter sleeve or a matching tapered shaft seat - the plain shaft diameter is smaller than 85 mm. |
| Locking Method | Adapter sleeve with nut and lockwasher, or a machined tapered shaft seat. Adapter sleeve NOT included. |

| Manufacturer Status | NSK, current range (NSKHPS spherical roller family) |
| Additional Attributes | NSK publishes identical load ratings and limiting speeds for the tapered-bore K version and the cylindrical-bore version - the suffix changes how the bearing mounts, not what it carries. Static rating exceeding dynamic rating is normal and correct for roller bearings and is not a data error. Chamfer r minimum 2.0 mm. The E4 heat-stabilisation code is not glossed letter by letter in NSK's literature; NSK specifies dimensional stability to 200 C across the range. Adapter sleeve designation deliberately not stated - confirm it against the manufacturer's own bearing-to-sleeve mounting table and your shaft diameter. Drive-up on the sleeve must be measured, not judged. |

NSK 22217EAKE4C3 double-row spherical roller bearing. Series 22217, 85 mm bore, 150 mm outside diameter, 36 mm width. Bore Type: Tapered, 1:12. Internal Clearance: C3. Cage Material: Wear-resistant nitrided pressed steel, roller-guided by central cage flanges.
The K in this designation is a 1:12 tapered bore. The bearing mounts on a matching tapered shaft seat or on an adapter sleeve that clamps onto a plain cylindrical shaft with a nut and lockwasher. Drive-up on the sleeve sets the running clearance during assembly. The plain shaft diameter under an adapter sleeve is smaller than the 85 mm bore.
222 is the double-row spherical roller, 22-dimension series. 17 is the bore code for 85 mm. EA is NSK’s high-capacity internal design with a nitrided pressed-steel cage guided by central flanges. K is the 1:12 tapered bore. E4 is heat stabilization to 200°C. C3 is radial internal clearance greater than normal. W33 is an annular lubrication groove with holes in the outer ring.
C3 clearance is specified where the inner ring runs hotter than the outer ring, or where an interference or taper-driven fit absorbs clearance in service, both conditions that apply to a tapered-bore bearing on an adapter sleeve. Dynamic Load Rating: 310 kN. Static Load Rating: 325 kN. Limiting Speed: 3,400 rpm grease, 4,300 rpm oil. Chamfer r minimum: 2.0 mm. NSK publishes identical ratings and speeds for the tapered-bore and cylindrical-bore versions of this bearing.
The W33 groove and outer-ring holes carry lubricant from the housing feed port directly to the rollers.
Equivalent designations in this tapered-bore, C3, W33 envelope: SKF 22217 EK/C3, FAG 22217-E1-XL-K-C3, NTN 22217EAKD1. The straight-bore 22217EAE4 shares the same ratings but mounts differently and is not a substitute.
