Neutral - KNAEE542215SW/K542291D | Matched Tapered Roller Bearings | 546.10 × 736.60 × 165.10 mm

Details

Neutral KNAEE542215SW/K542291D is a matched tapered roller bearings with inner diameter 546.10 mm, outer diameter 736.60 mm and width 165.10 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is a non-adjustable, extra-heavy duty double-row tapered roller bearing. It features two single-inner races (cones) paired with a unified, single-block double outer cup. This design provides high structural integrity by layout out two rows of rollers in a back-to-back configuration, which broadens the effective distance between the bearing's internal pressure centers. The back-to-back (TDO) design maximizes stability against overturning/tilting moments, making the assembly resilient to structural deflection or moderate angular misalignment under multi-ton loading. Unlike standard single tapered bearings that accept thrust loads strictly from one side, the dual-opposed roller angle anchors shafts firmly against axial displacement in both directions. Material : Manufactured from premium case-carburized (case-hardened) high-carbon chrome alloy steel. Features are : Logarithmic Roller Profile, Reduced Friction Torque, Optimized Lubrication Circuit, Vibration & Noise Attenuation, Temperature Resilience & Operating Thresholds. Applications : Construction, Mining & Quarrying Machinery, Metallurgical Equipment & Rolling Mills, Machine Tool Spindles, Agriculture Equipment, Pulp, Paper, and Texturing Mills, Material Handling Equipment. SW=Slotted Windows / Lubrication Mod, D=Double Cup Design.
