★ **Product Features** Thrust tapered roller bearings are designed with a circular table-shaped roller, where the large end is a spherical surface. These rollers are precisely guided by the raceway rim (shaft ring and housing). The design ensures that the shaft ring and raceway, as well as the conical surfaces of the roller, intersect at a single point along the bearing's central axis. One-way thrust tapered roller bearings can only handle axial loads in one direction. Two-way versions can manage axial loads in both directions. In two-way bearings, the middle ring typically fits with the shaft using a clearance fit, which requires an additional bushing or positioning mechanism to prevent axial movement. Bearings with a cover are especially useful for preventing dirt ingress and ensuring the rollers stay in place. Since they don’t have a cage, these bearings can accommodate a larger number of rollers, offering high axial load capacity but lower speed limits. They are generally used for one-directional axial loading applications. ★ **Primary Applications** - **One-way bearings**: Used in conjunction with ribbed raceways, suitable for radial positioning. Commonly applied in crane hooks, oil rig swivels, and other high-axial-load environments. Full-loaded roller bearings are recommended for heavy-duty applications. - **Two-way bearings**: Often found in rolling mill roll necks, where bidirectional axial forces are present. ● **Product Classification** - One-way thrust tapered roller bearing - Two-way thrust tapered roller bearing with outer cover - Thrust tapered roller bearing ■ **Size Range** - Inner Diameter: 50mm ~ 670mm - Outer Diameter: 85mm ~ 900mm - Width: 22mm ~ 230mm ◆ **Performance Standards** ZWZ thrust tapered roller bearings meet GB307.4 performance requirements. ZWZ offers products in P0, P6, and P5 grades. ★ **Cage Design** ZWZ thrust tapered roller bearings typically use solid brass cages or other types of solid cages. When brass is used, no rear code is marked. Other cage materials will have specific rear codes. ■ **Load Calculations** - Equivalent dynamic load: P_a = F_a - Equivalent static load: P_0a = F_a
