RHP22218EJW33CNSpherical Roller Bearing – Straight Bore, 90 mm ID, 160 mm OD, 40 mm Width, Open, W33 Lubrication Groove, CN Normal Internal Clearance.

Product Description

What this part is: RHP 22218EJW33CN 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: CN. Precision Class: P0. Precision Rating: Normal. Decoding the designation: E: reinforced high-capacity internal design, giving larger rollers and a higher load rating than the base execution on the same envelope. J: pressed cage. W33: an annular lubrication groove machined into the outer ring outside diameter with three radial feed holes running inward to the rolling elements. CN: normal internal radial clearance. Cage Type: Pressed, window type. Cage Material: Pressed steel. 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. Normal clearance suits a straight-bore mounting with a standard interference fit on the shaft. 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 E. Cross-Reference 2: FAG 22218-E1. Cross-Reference 3: Timken 22218EJW33. Cross-Reference 4: NSK 22218EAE4. Each is a 90 x 160 x 40 mm straight-bore, W33-grooved, high-capacity double-row spherical roller at normal clearance. 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.
