Specifically identified for usage within the Mack 64AX42 drivetrain architecture, this replacement part restores the original geometry necessary to handle increased radial loads experienced on the rear axles of commercial fleets. Proper installation of this bearing cup ensures that the rolling elements remain correctly supported, preventing unwanted clearance variations that lead to lubrication breakdown and accelerated component fatigue. Mechanics rely on the exact specifications associated with Timken products to secure the correct hardness rating and metallurgy when repairing differential carriers subject to constant torque fluctuations. Utilizing this branded bearing cup eliminates uncertainty regarding fitment dimensions, allowing operators to maintain consistent performance standards across their vehicle inventory without compromising efficiency or engineering reliability.\u003c\/p\u003e\u003c\/div\u003e","brand":"Mack","offers":[{"title":"New Surplus No Box","offer_id":46252995412202,"sku":null,"price":98.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-043.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/timken-72487-bearing-cup","provider":"GTG Hardware","version":"1.0","type":"link"}
