SNR22214VB33J30Double-Row Spherical Roller Bearing – Straight Bore, 70 mm ID x 125 mm OD x 31 mm Width, Open, C3 Internal Clearance, W33 Lubrication Groove

Product Description

What this part is: SNR 22214VB33J30 double-row spherical roller bearing. Manufacturer Part Number: 22214.V.B33.J30. Bearing Type: Spherical Roller Bearing. Series: 22200. Number Of Rows: 2. Rolling Elements: Spherical Roller. Bore: 70 mm. Outside Diameter: 125 mm. Overall Width: 31 mm. Bore Type: Straight. Item Weight: 1.58 kg (3.48 lb). Decoding the designation: V is the SNR conventional design generation: symmetrical rollers and no central rib on the inner ring, which opens the space between the two roller rows to lubricant flow. B33 is an annular groove machined into the outer ring outside diameter with three radial feed holes, the SNR form of the W33 lubrication feature. J30 is C3 internal clearance, greater than normal. Searchable forms of the part number: 22214VB33J30, 22214-V-B33-J30, 22214 V W33 C3, 22214VW33C3, 22214J, 22214CJ, 22214CCJ. What these specs mean in practice: Dynamic Load Rating: 211 kN (47,434 lbf). Static Load Rating: 228 kN (51,256 lbf). Limiting Speed: 4,300 rpm. Internal Clearance: C3. Precision Class: P0, ABEC 1. Cage Material: Pressed Steel. Cage Type: Pressed. Bearing Material: Chrome bearing steel. Closure Type: Open. Operating Temperature Range: -30 to +200 °C. Maximum Permissible Misalignment: 1.5°. Two rows of spherical rollers run on a common sphered outer raceway, so the bearing carries heavy radial load together with thrust in either axial direction, and the inner ring and roller set swivel inside the outer ring to absorb shaft deflection under load and angular error between two housings. On a double-row spherical roller the static rating sits above the dynamic rating, because the load is shared across two rows of long rollers in simultaneous contact. C3 clearance leaves working room for an interference fit on the shaft and for the temperature difference between inner and outer ring under heavy load. Lubrication feature: Lubricant: grease or oil. The W33 groove distributes lubricant circumferentially around the outer ring and its three radial holes carry it inward to the rolling elements, so the bearing takes fresh lubricant in service from a grease gun, a single-point lubricator, a centralised grease line or a circulating-oil supply. With no central rib between the roller rows, lubricant passes freely from one row to the other. The rings are dimensionally stabilised for running temperatures to +200 °C. Quantity and configuration: Unit Quantity: 1 Pc. One complete double-row spherical roller bearing, straight bore, open on both faces, mounting directly on a cylindrical shaft seat. Interchange guidance: Same-envelope 70 x 125 x 31 mm spherical rollers at C3 clearance: SKF 22214 E/C3, FAG 22214-E1-C3, NTN 22214C3, NSK 22214EAE4C3, Koyo 22214RHRC3. The current high-capacity E-generation executions share these boundary dimensions and carry higher load ratings than the conventional V design. Design Units: Metric.
