87673373 Front Axle Kingpin Pinion Steering Thrust Bearing 25x62x22.5mm
Measuring exactly 25.00 mm inside diameter (ID), 62.00 mm outside diameter (OD), and 22.50 mm in width (W), this high-capacity structural bearing is engineered to isolate intense axial forces. Positioned primarily within heavy-duty four-wheel-drive (4WD) front axle steering kingpin housings or independent transmission pinion shaft clusters, it manages heavy directional shock loads, ensures low-friction wheel spindle rotation, and maintains structural alignment under massive front-end implement weight stresses. ?

Case IH / Case Construction Backhoes: 580 Super N / 580N / 590 Super N (Front axle spindle linkages). Type: Axial Thrust Roller / Angular Structural Bearing Assembly. Inside Diameter (ID): 25.00 mm. Outside Diameter (OD): 62.00 mm. Overall Width (W): 22.50 mm. Material Matrix: High-density chrome steel alloy (through-hardened and precision ground). Condition: 100% Brand new original CNH equipment premium drivetrain mechanical hardware. Through-hardened chrome steel construction eliminates internal roller flattening and race pitting under peak weights. Precision-ground rolling elements guarantee smooth rotational tracking and minimize operational friction heating. Instantly cures severe front-wheel steering wander, kingpin housing clunking, and erratic wheel hub vibration. Ultra-robust 22.50 mm width profile offers expansive contact surface areas to withstand immense lateral fields. Heavy industrial finish accommodates heavy-load lithium grease containment cycles within steering seals. Crushed or binding kingpin steering bearing swaps, full 4WD front hub rebuilds, and axle spindle overhauls. Loose front wheel play diagnostics, severe steering binding troubleshooting, and drive knuckle adjustments. Pre-season agricultural fleet readiness checks, heavy front loader tractor updates, and workshop service tasks. Please check your machine’s exact front axle or transmission assembly blueprint to confirm the specific dimensional parameters (25x62x22.5mm) required before concluding final placement. Thoroughly clean out all oxidized grease, caked grit, and old metal particles from the housing cavity before pressing in the new bearing. Apply a generous layer of premium heavy-duty extreme-pressure (EP) wheel bearing grease to the internal rollers during installation, and verify that the surrounding oil seals are intact to lock out field mud, dust, and moisture tracking loops.
