Single Row Tapered Roller Bearings 30664

Single Row Tapered Roller Bearings (Model: 30664) 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 320mm, outer diameter of 620mm, and width of 125mm (total width 141mm), they offer a dynamic radial load capacity of 2780kN and static radial load capacity of 4600kN. Suitable for heavy machinery (e.g., mining equipment, construction machinery), 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.
