{"product_id":"high-strength-overlay-plate-engine-bearing","title":"High-Strength Overlay Plate Engine Bearing","description":"The ACL RACE Series performance engine bearings are a premier choice in motorsports, recognized for their endurance and capability in demanding applications. This standard size rod bearing is engineered with a unique combination of design, metallurgy, and engineering for optimal performance and longevity. Features include a high-strength overlay plate with reduced thickness for superior fatigue resistance and hardened steel backs to improve bearing lining support and housing retention.\n\nAdditional benefits of this ACL bearing set include increased crush for enhanced retention within the housing and the elimination of flash plating on the back of the bearings. This design choice promotes better heat transfer and maximizes the grip between the bearings and their housing. The increased eccentricity is incorporated to compensate for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films, while tight, consistent wall tolerances help maintain precise clearances. Enlarged ID chamfers on bearing edges are included where necessary to accommodate large fillet radius on performance crankshafts.\n\nThis specific rod bearing set is designed for a direct fit in the 2012-2017 BMW F12\/F13 and 2012-2017 BMW F01\/F02 models. Its specifications include a shaft diameter of 2.1256 inches and a width of 0.591 inches, with a material designation of F781. It is part of the ACL RACE Series, known for its application in record-setting and championship-winning race engines across various motorsports disciplines.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686753169720,"sku":"5M1573H-STD+8B1578H-STD","price":227.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661162715.webp?v=1784876332","url":"https:\/\/store.motormia.co\/products\/high-strength-overlay-plate-engine-bearing","provider":"MOTORMIA","version":"1.0","type":"link"}
