Neutral - KNA48680DGWSH/K48620-K48620D | Four Row Tapered Roller Bearing | 139.70 × 200.02 × 157.16 mm

Details

Neutral KNA48680DGWSH/K48620-K48620D is a four row tapered roller bearing with inner diameter 139.70 mm, outer diameter 200.02 mm and width 157.16 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is a heavy-duty, non-adjustable design four-row imperial tapered roller bearing predominantly utilized for the roller necks of metal rolling mills and extremely heavy industrial axles.The multi-row tapered design allows the bearing to manage immense simultaneous radial and axial loads. It is built for equipment that experiences severe thrust forces alongside heavy downward weight. By spreading the load across multiple rows of rollers, it minimizes structural deflection and prevents stress concentration on the machine shaft. Material : The bearing is manufactured from high-purity, case-hardened (carburised) alloy steel to provide a wear-resistant outer shell and a shock-absorbing inner core. Features are : Integrated Lubrication Grooves & Holes, Reduced Friction, Logarithmic Roller Profiling, Super-Finished Raceways, Vibration and Noise Dampening, Thermal Stabilization, Extended Service Lifecycle. Applications : Mining & Extraction Machinery, Renewable Energy & Power Generation, Aerospace & Defense Equipment, Paper Mill Press Sections, Construction Equipment, Oilfield & Drilling Equipment, Industrial Gearboxes & Power Transmission, Cement and Aggregate Processing. D=Double Cone Inner Ring, GW=Groove and Window/Holes, SH=Spiral (Helical) Anti-Creep Groove, D=Double Cup Design.
