SNR21313VC3Spherical Roller Bearing – Straight Bore, 65 mm ID, 140 mm OD, 33 mm Width, Open, C3 Internal clearance

Product Description

What this part is: SNR 21313VC3 double-row spherical roller bearing, ISO 213 light series, 65 x 140 x 33 mm. Bore: 65 mm. Outside Diameter: 140 mm. Overall Width: 33 mm. Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Series: 213. Part Number: 21313VC3. Base Number: 21313. Design Units: Metric. Bearing Material: Bearing steel. Decoding the designation: Base Number: 21313, setting the 65 x 140 x 33 mm envelope. Design Generation: V, the SNR conventional design that precedes the Ultage range — symmetrical rollers and no central guide rib on the inner ring. Internal Clearance: C3, written J30 in the alternative SNR suffix form. Bore Type: Straight. Searchable variants of the number: 21313VC3, 21313VJ30, 21313.VC3, 21313-V-C3, 21313 V C3, 21313CJ C3. Ratings and running limits: Dynamic Load Rating: 224 kN. Static Load Rating: 215 kN. Fatigue Load Limit: 25.8 kN. Reference Speed: 4400 rpm. Limiting Speed: 5900 rpm. Precision Class: P0, ABEC 1. Operating Temperature Range: –40 °C to +200 °C. Item Weight: 2.41 kg (5.31 lb). Harmonization Code: 8482.30.00. Cage and internal design: Cage Type: Pressed. Cage Material: Steel. Permissible Misalignment: 0.5° at normal load. The two roller rows share one concave outer-ring raceway, so the inner ring and roller set swivel within the outer ring and absorb shaft deflection and housing misalignment while carrying heavy radial load with an axial component in either direction. What these specs mean in practice: C3 clearance is one step greater than normal. Greater clearance absorbs the running clearance lost to an interference fit on the shaft and to a temperature gradient across the bearing, so C3 suits a heavier press fit and a hotter inner ring. The 213 light section runs a slimmer outer ring than the 223 series on the same shaft, so it fits a smaller housing bore. Maximum Operating Temperature: 200 °C. Mounting dimensions: Inner Ring Outside Diameter (d2): 85.8 mm. Outer Ring Inside Diameter (D1): 119.7 mm. Minimum Bearing Fillet Radius (rs min): 2.1 mm. Maximum Abutment Fillet Radius (ra max): 2 mm. Minimum Shaft Shoulder Diameter (da min): 77 mm. Maximum Housing Shoulder Diameter (Da max): 128 mm. Calculation Factors: e 0.23, Y0 2.84, Y1 2.91, Y2 4.33. Quantity and configuration: Unit Quantity: 1 Pc. One complete bearing ships as a single assembled unit — outer ring, inner ring, two rows of spherical rollers and the pressed steel cages. Interchange guidance: GTIN: 3413520079390. Manufacturer Part Number: 21313VC3. On the same 65 x 140 x 33 mm envelope and the same C3 clearance class: SKF 21313 E/C3, FAG 21313-E1-C3, Timken 21313CJ-C3, NTN 21313VC3. Interchange holds on envelope and clearance class; the load ratings of the later E and Ultage executions differ from the conventional V design.
