SNR22206VB33J30Double-Row Spherical Roller Bearing – Straight Bore, 30 mm ID x 62 mm OD x 20 mm Width, Open, C3 Internal Clearance, W33 Lubrication Groove

Product Description

What this part is

SNR 22206VB33J30 double-row spherical roller bearing. Manufacturer Part Number: 22206.V.B33.J30. Bearing Type: Spherical Roller Bearing. Series: 22200. Number Of Rows: 2. Rolling Elements: Spherical Roller. Bore: 30 mm. Outside Diameter: 62 mm. Overall Width: 20 mm. Bore Type: Straight.

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: 22206VB33J30, 22206 V W33 C3, 22206.V.B33.J30, 22206VW33C3, 22206J, 22206CJ.

What these specs mean in practice

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. The sphered raceway lets the inner ring and roller set swivel inside the outer ring, taking up shaft deflection under load and angular error between two housings. 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. The rings are dimensionally stabilised for running temperatures to +200 °C.

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.

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 30 x 62 x 20 mm spherical rollers: SKF 22206 E, FAG 22206-E1, NTN 22206EAW33, Koyo 22206RHR, NSK 22206EAE4. Those are current high-capacity E-generation executions on the same boundary dimensions, so their load ratings differ from the conventional V design. Harmonization Code: 8482.30.00.
