Single Row Tapered Roller Bearings (Model: 30330) 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 150mm, outer diameter of 320mm, and width of 65mm (total width 72mm), they offer a dynamic radial load capacity of 815kN and static radial load capacity of 1050kN. Suitable for medium industrial equipment (e.g., gearboxes, conveyors), these bearings are widely used in automotive axles, industrial gearboxes, and heavy machinery applications. Equipped with a Standard cage, the bearing supports grease or oil lubrication 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.
