Product Description

What this part is

RHP 22218HLW33C3 double-row spherical roller bearing. Series: 22200. Bore: 90 mm. Outside Diameter: 160 mm. Overall Width: 40 mm. Bore Type: Straight. Number Of Rows: 2. Rolling Elements: Spherical Rollers. Bearing Material: Chrome bearing steel. Closure Type: Open. Internal Clearance: C3. Precision Rating: Normal.

Decoding the designation

W33: an annular lubrication groove machined into the outer ring outside diameter with three radial feed holes running inward to the rolling elements. C3: internal radial clearance greater than normal. Cage Type: Machined. Cage Material: Brass.

What these specs mean in practice

Dynamic Load Rating: 339 kN / 76,209 lbf. Static Load Rating: 406 kN / 91,271 lbf. Limiting Speed: 3,400 rpm on oil and 2,600 rpm on grease. Two rows of barrel rollers run on a common spherical raceway in the outer ring, so the bearing carries very high radial load, takes thrust in both directions, and accommodates shaft misalignment and housing deflection without concentrating stress at the roller ends. A machined brass cage is dimensionally stable at elevated temperature and tolerates shock loading and marginal lubrication better than a pressed cage. C3 clearance leaves room for thermal growth of the shaft in service. Max Temp: 200°C. Min Temp: -30°C.

Lubrication

Lubricant: grease or oil. The W33 groove distributes lubricant circumferentially around the outer ring and its three radial holes carry it inward to both roller rows. The same passages serve a grease gun, an automatic single-point lubricator, a centralised grease system, or circulating-oil and oil-mist feed.

Bore form and mounting

Bore Type: Straight. The bearing mounts directly on a cylindrical shaft seat at an interference fit. The designation carries no K, so this is the parallel-bore execution of the 22218.

Quantity and configuration

Unit Quantity: 1 Pc. Item Weight: 7.50 lbs.

Interchange guidance

Cross-Reference 1: SKF 22218 CC/W33. Cross-Reference 2: FAG 22218-E1-C3. Cross-Reference 3: Timken 22218EMW33C3. Each is a 90 x 160 x 40 mm straight-bore, W33-grooved double-row spherical roller. A 22218K carries a 1:12 tapered bore for an adapter sleeve on the same envelope and is a related size rather than a direct substitution.
