Timken Tapered Roller Bearings Guide
Product Description
The Timken EE141250D / 142551 / 142550XD four-row tapered roller bearing features a TQO configuration consisting of two double cones without face slots, four rows of tapered rollers and cages, two single cups, one double cup, one cone spacer, and two cup spacers. This design provides high radial and axial load capacity, excellent structural rigidity, and reliable stability under heavy combined loads. The robust four-row arrangement helps distribute rolling forces evenly, while the cone and cup spacers maintain proper axial spacing and support stable bearing operation.
The Timken EE141250D / 142551 / 142550XD bearing is engineered 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 EE141250D / 142551 / 142550XD bearings.
