The 51 series single direction thrust ball bearing (model: 51104) is designed to handle axial loads in one direction. It features a one-piece solid brass cage and chrome steel (GCr15) construction with carbonitriding treatment for enhanced durability. The bearing has a bore diameter of 20mm, outer diameter of 35mm, and height of 10mm, providing dynamic load capacity of 15.1kN and static load capacity of 29kN. This bearing is ideal for applications such as machine tool spindles, automotive transmissions, and industrial pumps, particularly suited for light industrial machinery such as conveyors and small pumps. Compliant with ISO 9001 standards, it supports grease lubrication (with oil lubrication option for high-speed applications) and operates within a temperature range of -30°C to +120°C. During installation, a recommended torque of 30-60 N·m is advised for 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.
