Product Description
Four Row Tapered Roller Bearings (Model: 3806/1260) are engineered for applications requiring maximum radial and axial load capacity in both directions. Constructed from premium-grade chrome steel (GCr15) with advanced heat treatment and precision grinding, these bearings deliver superior hardness, fatigue resistance, and dimensional stability. With a bore diameter of 1260mm, outer diameter of 1640mm, and width of 1000mm (total width 1000mm), they offer a dynamic radial load capacity of 38300kN and static radial load capacity of 141000kN. This four-row configuration provides exceptional radial and axial load capacity in both directions,
making it ideal for applications with complex load profiles. The symmetrical design ensures
uniform load distribution across all rows of rollers, minimizing stress concentrations and
extending service life under extreme loads. Suitable for specialized heavy machinery (e.g., large-scale mining equipment, steelmaking machinery), these bearings are critical components in steel rolling mills, heavy mining equipment, and large-scale industrial machinery. Equipped with a Pressed steel cage, the bearing requires forced oil circulation with temperature monitoring to maintain optimal performance. It offers low to moderate speed due to extreme load capacity and operates within a temperature range of -20°C to +100°C. Compliant with ISO 9001 , installation requires meticulous alignment and preload adjustment. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
