Timken Tapered Roller Bearings Guide
Product Description
The Timken NP323192 / NP335700 / NP589146 four-row tapered roller bearing features a TQOW configuration consisting of two double cones, four rows of tapered rollers and cages, one cone spacer, two single cups, two cup spacers, and one double cup. This design provides high radial and axial load capacity, excellent rigidity, and reliable stability under heavy combined loads. Lubrication slots on the cone faces facilitate lubricant distribution, while the hardened cone spacer helps minimize face wear and supports long-term bearing performance.
The Timken NP323192 / NP335700 / NP589146 bearing is designed for rolling mill roll-neck applications, including work rolls, intermediate rolls, and backup rolls in flat product mills, as well as work rolls in long product mills. Its robust four-row construction supports heavy rolling loads, stable roll positioning, and consistent performance under demanding operating conditions. HSN provides replacement bearing solutions for United States steel mills, OEM equipment manufacturers, and industrial distributors seeking alternatives to Timken NP323192 / NP335700 / NP589146 bearings.
