SNR22216EAKB33J30Double-Row Spherical Roller Bearing, 80 x 140 x 33 mm, 1:12 Tapered Bore, ULTAGE High-Capacity Design, W33 Lubrication, C3 Clearance, 200 C Rated

Product Description

What this part is:

SNR 22216 EA.K.B33.J30 double-row spherical roller bearing: 80 mm tapered bore (1:12), 140 mm outside diameter, 33 mm width, C3 internal clearance. NTN-SNR ULTAGE high-capacity design with a lubrication groove and three holes through the outer ring. Unit Quantity: 1 Pc. Complete non-separable bearing: inner ring with the 1:12 tapered bore, two rows of symmetrical rollers, two window-type drawn steel cages, and outer ring with the lubrication groove and three holes.

Decoding the designation:

222 — double-row spherical roller bearing, ISO dimension series 22.

16 — bore code, 16 x 5 = 80 mm bore.

EA — NTN-SNR ULTAGE increased-capacity design: symmetrical rollers, no central inner-ring rib, steel stabilised for use to +200 °C. The A specifies two window-type drawn steel cages centred on the ground surface of the inner ring, each roller guided by a four-tang pocket.

K — tapered bore, taper 1:12.

B33 — SNR code for a lubrication groove and holes in the outer ring, equivalent to the industry W33 code.

J30 — SNR clearance and precision code. The first digit is the ISO radial internal clearance class, 3 = C3, greater than normal. The second digit is the ISO precision class, 0 = normal class.

Specifications:

Bore Diameter: 80 mm. Outside Diameter: 140 mm. Width: 33 mm. Bore Type: Tapered 1:12. Number Of Rows: 2. Internal Clearance: C3. Cage Material: Drawn steel. Cage Type: Two window-type cages. Precision: ISO normal class (P0).

Dynamic Load Rating Cr: 277 kN. Static Load Rating C0r: 286 kN. Fatigue Load Limit Cu: 33.7 kN. Reference Speed, grease: 4,300 rpm. Limiting Speed, oil: 5,800 rpm. Maximum Operating Temperature: 200 °C.

The spherical outer raceway lets the inner-ring assembly swivel, so the bearing self-aligns to shaft deflection or housing misalignment and carries radial load plus axial load in both directions.

Dimensions and mounting:

Chamfer rs min: 2 mm. Fillet ra max: 2 mm. Shaft abutment da min: 91 mm. Housing abutment Da max: 129 mm. Inner ring shoulder d2: 94.9 mm. Outer ring shoulder D1: 126.7 mm. Outer ring lubrication groove width: 7.87 mm. Lubrication hole diameter: 3.5 mm, three holes. Axial load factors: e 0.22, Y1 3.14, Y2 4.67, Y0 3.07.

Bore Type: Tapered 1:12. The bearing mounts on an H316 adapter sleeve, which makes the shaft seat under the sleeve 70 mm, or on a machined 1:12 tapered shaft seat. Matching accessories: H316 adapter sleeve (70 mm shaft), AH316 withdrawal sleeve, KM16 locknut, MB16 lockwasher.

Compatibility and replacement:

Cross-Reference 1: NTN 22216EAKW33C3, the same ULTAGE design under the NTN name. Cross-Reference 2: FAG 22216-E1-K-C3. Cross-Reference 3: SKF 22216 EK/C3W33. Cross-Reference 4: Koyo 22216RHKW33C3. Cross-Reference 5: NSK 22216CDKE4C3, pressed steel cage. Cross-Reference 6: Timken 22216KEJW33C3, stamped steel cage. All are tapered-bore, relubricatable 22216 bearings with C3 clearance. 22216E is the E-design base number for the 80 x 140 x 33 mm envelope. 53516 is the GOST designation.
