TIMKEN 22218KCJW33

Timken 22218KCJW33 Spherical Roller Bearing Description The Timken 22218KCJW33 is a high-performance spherical roller bearing designed for reliability in demanding industrial environments. It features two rows of rollers, a common sphered outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. This design allows the bearing to accommodate misalignment and handle heavy radial and axial loads. The tapered bore allows for mounting on a tapered journal or using an adapter sleeve. Specifications Manufacturer: Timken Part Number: 22218KCJW33 Type: Spherical Roller Bearing Bore Diameter: 90 mm Outer Diameter: 160 mm Width: 40 mm Bore Type: Tapered (1:12) Cage Material: Stamped Steel (CJ) Lubrication Feature: Annular groove and three holes in outer ring (W33) Dynamic Load Rating: 345 kN Static Load Rating: 410 kN Application Ideal for use in heavy machinery such as gearboxes, pumps, fans, conveyors, and mining and construction equipment where high loads and potential shaft misalignment are present. Country of Origin Manufactured by Timken, a global leader in bearings and power transmission products, typically in the USA or Europe. CO2 Impact Choosing a pre-owned but unused bearing like this one prevents the emission of approximately 7.5 kg of CO2 compared to manufacturing a new one. This is a sustainable choice for your operations. Availability This item is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. FAQ What is the significance of the ‘K’ and ‘W33’ suffixes in the part number 22218KCJW33? The ‘K’ indicates that the bearing has a tapered bore with a standard taper of 1:12. This allows for mounting on a tapered shaft or with an adapter sleeve for a cylindrical shaft. The ‘W33′ suffix signifies that the bearing has a lubrication groove and three lubrication holes in the outer ring to facilitate efficient relubrication. What is the proper mounting procedure for a tapered bore bearing like this one? Mounting a tapered bore bearing involves driving it up the tapered seat to achieve the correct internal clearance reduction. This is typically done using a hydraulic nut or by carefully measuring the axial drive-up distance. It is crucial to follow the manufacturer’s guidelines to avoid damaging the bearing or achieving incorrect preload. Can this bearing be used with oil or grease lubrication? Yes, the Timken 22218KCJW33 is suitable for both oil and grease lubrication. The choice depends on the application’s operating speed, temperature, and load conditions. The W33 feature makes it particularly easy to relubricate with grease while in service.
