Product Description

What this part is

RHP 22213EJW33C3 double-row spherical roller bearing, straight bore, open, with the W33 lubrication groove in the outer ring. Series: 222. Bore: 65 mm. Outside Diameter: 120 mm. Width: 31 mm. Bore Type: Straight. Rolling Elements: Spherical Roller. Number Of Rows: 2. Internal Clearance: C3.

Decoding the designation

22213 — the ISO 22213 size, 65 x 120 x 31 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: 221,000 N (221 kN). Static Load Rating: 230,000 N (230 kN). Limiting Speed: 4,300 r/min on grease, 5,300 r/min on oil bath. Internal Clearance: C3. Cage Material: Steel. Cage Type: Pressed. Chamfer r min: 1.5 mm. Mass: 1.51 kg. Calculation factors e 0.24, Y2 4.2, Y3 2.8, Y0 2.7.

Two rows of barrel rollers run on a single spherical raceway in the outer ring, so the inner ring, rollers and cage can 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. The static rating sitting above the dynamic rating is normal for this type. C3 clearance leaves room for the interference fit and the temperature difference across the rings.

Mounting data

Shaft abutment diameter da: 74 mm minimum, 80 mm maximum. Housing abutment diameter Da: 107 mm minimum, 111 mm maximum. Shaft or housing fillet radius ra: 1.5 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.
