SNR 21308V double-row spherical roller bearing, ISO 213 series, 40 x 90 x 23 mm. Bore: 40 mm. Outside Diameter: 90 mm. Overall Width: 23 mm. Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Series: 213. Part Number: 21308V. Base Number: 21308. Design Units: Metric.
Dynamic Load Rating: 97.7 kN. Static Load Rating: 86.7 kN. Fatigue Load Limit: 10.6 kN. Reference Speed: 6400 rpm. Limiting Speed: 9300 rpm. Precision Class: P0, ABEC 1. Internal Clearance: CN. Operating Temperature Range: –40 °C to +200 °C. Item Weight: 0.715 kg (1.6 lb).
Cage Material: Steel. Cage Type: Pressed. Both roller rows run on a single sphered outer raceway, so the inner ring, roller and cage assembly swivels inside the outer ring. Permissible Misalignment: 0.5° at normal load. Contact Angle: not applicable to a spherical roller bearing.
Two rows of spherical rollers carry high radial load and take thrust in both directions. CN internal clearance is the standard radial clearance group and suits an interference fit on a straight shaft seat. Maximum Operating Temperature: 200 °C. The self-aligning geometry absorbs shaft deflection and housing misalignment without concentrating load at the roller ends.
Inner Ring Outside Diameter (d2): 53.5 mm. Outer Ring Inside Diameter (D1): 75.4 mm. Minimum Bearing Fillet Radius (rs min): 1.5 mm. Maximum Abutment Fillet Radius (ra max): 1.5 mm. Minimum Shaft Shoulder Diameter (da min): 49 mm. Maximum Housing Shoulder Diameter (Da max): 81 mm. Calculation Factors: e 0.26, Y0 2.5, Y1 2.55, Y2 3.8.
Unit Quantity: 1 Pc. Single bearing with a straight bore, mounted directly on the shaft seat.
GTIN: 3413520079154. Manufacturer Part Number: 21308V. Also written 21308-V, 21308.V and 21308 V, and marked on cartons as 21308-CJ. Same-envelope equivalents in the ISO 213 series: SKF 21308 E, FAG 21308-E1, NTN 21308V.
