RHP22209EJW33C3Spherical Roller Bearing – Double Row, Straight Bore, 45 mm ID, 85 mm OD, 23 mm Width, W33 Lubrication Groove, C3 Internal Clearance

Product Description

What this part is: RHP 22209EJW33C3 double-row spherical roller bearing, straight bore, open, with the W33 lubrication groove in the outer ring. Series: 222. Bore: 45 mm. Outside Diameter: 85 mm. Width: 23 mm. Bore Type: Straight. Rolling Elements: Spherical Roller. Number Of Rows: 2. Internal Clearance: C3. Decoding the designation: 22209 — the ISO 22209 size, 45 x 85 x 23 mm, dimension series 22. E — increased capacity design. J — pressed cage. W33 — annular lubrication groove around the outer ring outside diameter with three radial feed holes into the rolling elements. C3 — radial internal clearance one band wider than CN. What these specs mean in practice: Dynamic Load Rating: 118,000 N (118 kN). Static Load Rating: 111,000 N (111 kN). Limiting Speed: 6,000 r/min on grease, 7,500 r/min on oil bath. Internal Clearance: C3. Cage Material: Steel. Cage Type: Pressed. Chamfer r min: 1.1 mm. Mass: 0.55 kg. Calculation factors e 0.26, Y2 3.9, Y3 2.7, Y0 2.6. Two rows of barrel rollers run on a single spherical raceway in the outer ring, so the inner ring, rollers and cage swivel inside the outer ring. That accommodates shaft deflection and housing misalignment without edge-loading the rollers, which is what makes this the standard bearing for conveyor pulleys, fans, crushers and long unsupported shafts. Thrust is carried in both directions. C3 clearance leaves room for the interference fit and the temperature difference across the rings. Mounting data: Shaft abutment diameter da: 52 mm minimum, 55 mm maximum. Housing abutment diameter Da: 75 mm minimum, 78 mm maximum. Shaft or housing fillet radius ra: 1 mm maximum. The W33 groove and its three radial holes take lubricant from the housing lubrication port and distribute it circumferentially around the outer ring before feeding it inward to the rollers. Lubricant: grease or oil. Quantity and configuration: Unit Quantity: 1 Pc. Straight bore, mounted directly on the shaft seat. Interchange guidance: Cross-references: Timken 22209EJW33C3, NSK 22209EAE4C3. SKF 22209 E/W33 and FAG 22209-E1-XL-W33 as written carry normal (CN) clearance, not C3. Searchable variants of the designation: 22209EJW33C3, 22209-E-J-W33-C3, 22209 EJ W33 C3, 22209E, 22209EJW33. A 22209K is the tapered-bore form of the same size and mounts on an H309 adapter sleeve instead of directly on the shaft.
