Single Row Tapered Roller Bearings (Model: 329/630) are designed to handle combined radial and axial loads efficiently, with exceptional capacity for unidirectional axial forces. Constructed from high-quality chrome steel (GCr15) with precision grinding, these bearings ensure reliable performance under heavy loads and harsh environments. With a bore diameter of 630mm, outer diameter of 850mm, and width of 132mm (total width 132mm), they offer a dynamic radial load capacity of 3080kN and static radial load capacity of 7150kN. Suitable for large-scale industrial systems (e.g., rolling mills, marine propulsion), these bearings are widely used in automotive axles, industrial gearboxes, and heavy machinery applications. Equipped with a Standard cage, the bearing supports forced oil circulation and provides standard speed rating. Compliant with ISO 9001 standards, it operates within a temperature range of -30°C to +120°C and requires careful preload adjustment during installation to maximize service life. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
