SNR 21306V double-row spherical roller bearing. Series: 21300. Base Number: 21306. Bore: 30 mm. Outside Diameter: 72 mm. Overall Width: 19 mm. Bore Type: Straight. Closure Type: Open. Number Of Rows: 2. Rolling Elements: Spherical Roller. Cage Material: Pressed steel. Cage Type: Pressed. Internal Clearance: CN. Precision Rating: ABEC 1 / P0. Bearing Material: Chrome steel. Item Weight: 0.394 kg (0.87 lb). Searchable variants of the number: 21306V, 21306.V, 21306-V, 21306 V.
Series: 21300 — the light double-row spherical roller series. V: internal design modification. The designation carries no K, so the bore is straight and the inner ring seats directly on a cylindrical shaft. Internal Clearance: CN — the normal radial clearance class.
Dynamic Load Rating (C): 64.6 kN (14,523 lbf). Static Load Rating (C0): 52.1 kN (11,713 lbf). Fatigue Limit Load (Cu): 6.1 kN (1,371 lbf). Reference Speed (N ref): 7,800 r/min. Limiting Speed (N lim): 12,000 r/min. Operating Temperature Range: −40 °C to 200 °C.
e: 0.28. Y0: 2.39. Y1: 2.45. Y2: 3.64. Inner Ring Outside Diameter (d2): 40.8 mm. Outer Ring Inside Diameter (D1): 59.7 mm. Minimum Chamfer Radius (rs): 1.1 mm. Maximum Shaft And Housing Fillet Radius (ra): 1 mm. Minimum Inner Ring Abutment Diameter (da): 37 mm. Maximum Outer Ring Abutment Diameter (Da): 65 mm.
Two rows of barrel rollers run on a common spherical raceway in the outer ring, so the inner ring and roller set swivel inside the outer ring. Permissible Misalignment: 0.5° at normal load, which absorbs shaft deflection and housing bore misalignment. The double-row arrangement takes axial load in both directions alongside the radial load. The fatigue limit load of 6.1 kN is the figure that governs continuous service life.
Unit Quantity: 1 Pc. Single bearing, open on both faces, straight bore.
Same-envelope equivalents: SKF 21306 E, FAG 21306-E1, NSK 21306EAE4. Load ratings and cage execution differ between makers. The NSK 21306EAE4 carries a W33 lubrication groove and three radial feed holes in the outer ring.
