These support the crankshaft in the block, and in a performance engine, they are responsible for ensuring oil reaches the entire crankshaft properly.\u003c\/p\u003e\u003cp\u003eInternally, they feature three layers on a high-strength steel backing: a copper-lead-tin lining, a thin nickel barrier, and a lead-tin-copper sliding layer that works against the crankshaft.\u003c\/p\u003e\u003cp\u003eThe upper bearings have a full 180° oil groove, while the lower bearings have a partial groove to avoid interrupting oil flow to the connecting rods; the end of the groove is tapered to prevent pressure spikes. ACL manufactures them with more \"crush\" (housing interference) than standard bearings to ensure they are held securely and dissipate heat better, along with increased eccentricity, which helps maintain the oil film when the housing deforms at high RPM.\u003c\/p\u003e\u003cp\u003eIn standard size, ACL specifies them for a crankshaft journal of 54.985 to 55.000 mm, and recommends an oil clearance of about 0.057 to 0.068 mm for that diameter. If the crankshaft has been ground, the measurement changes.\u003c\/p\u003e\u003cp\u003eThey do not have the silver tin flash plating of standard bearings, so their dark, brownish-black-bluish color is the factory finish and does not indicate any defect. ACL advises against polishing the bearing surface to adjust clearance; if more is needed, combine them with the HX version, which provides an additional 0.025 mm of clearance.\u003c\/p\u003e\u003cp\u003eIf the crankshaft has been ground or you are unsure of the required size, contact us with your engine code before ordering.\u003c\/p\u003e","brand":"ACL","offers":[{"title":"Default Title","offer_id":50813125329230,"sku":"ACL-5M8361H\/134","price":108.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/0d6ef245fbcfa5cf75ec412070eb9a3c.jpg?v=1735903940","url":"https:\/\/driftandgrip.com\/en\/products\/acl-trimetal-reinforced-main-bearings-toyota-3sge-3sgte","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
