The 53 series single direction thrust ball bearings with a sphered housing washer (Model: 53318) are engineered to handle axial loads in one direction efficiently. Featuring a U318, these bearings provide self-aligning capabilities to compensate for angular misalignment in mounting surfaces, ensuring uniform load distribution and extended service life. Manufactured from ISO 9001-certified chrome steel (GCr15) with carbonitriding treatment, they offer exceptional wear resistance and fatigue strength. With a bore diameter of 90mm, outer diameter of 155mm, and height of 59mm, these bearings deliver a dynamic load capacity of 182kN and static load capacity of 440kN. Ideal for heavy-duty machinery (e.g., rolling mills, mining equipment), they are particularly suited for applications requiring self-aligning capabilities under axial loads. Compliant with ISO 9001 standards, these bearings support grease lubrication (oil lubrication available for high-speed operations) and operate within a temperature range of -30°C to +120°C. During installation, a recommended torque of 80-150 N·m is advised for housing washer bolts to ensure optimal performance. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
