Yesterday’s engine bearings’ load capacity no longer works for today’s sport compact race engines. Tomorrow’s engines will be even more powerful.\u003cbr\u003e\u003cbr\u003eKing bearings meet these demands with higher performance benchmarks, advanced materials and unique geometrical features.\u003cbr\u003eKing Racing’s SV, GPC, XP, and XPC series of rod and main bearings were developed to meet these challenges through technologically advanced geometrical features and a unique metal structures. Together, they drive the industry to a higher level of durability, performance and expectation.\u003c\/p\u003e \u003cp\u003epMax Black is a unique tri-metal structure the has been developed to meet the ongoing demand for bearings with increased load capacity. As engines evolve and gain more power, engine bearings have to be able to handle the extra loading.\u003c\/p\u003e \u003cp\u003epMax Black consists of three layers that come together to form the strongest tri-metal bearing in the industry with load capacity exceeding the competition by as much as 24%. King Racing’s new hardening technology modifies the overlay molecular structure and creates a fatigue resisting shield.\u003c\/p\u003e \u003cp\u003eThe intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMax Black intermediate layer, we increased the tin content to 4.5%, making it 22% harder (115 HV), with a load carrying capacity of 17,000 psi.\u003c\/p\u003e \u003cp\u003eThe overlay of a typical high performance bearing consists of a leaded alloy that contains 2-3% copper. It achieves a hardness level of 11 – 14 HV, and a maximum load capacity of 8,000-8,500 psi. King’s pMaxBlack overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process.\u003c\/p\u003e \u003cp\u003eThe pMaxBlack overlay contains 5% copper. It is further strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue-resistant shield. The outcome is a significant 29% increase in overlay hardness (18.1HV) and overall 24% increase in load capacity (10,200 psi).\u003c\/p\u003e \u003cp\u003eSecureBond – Maximum tri-metal structural integrity\u003c\/p\u003e \u003cp\u003eHigh loads and high RPM’s create critical stresses that travel through the multi-layer construction of a tri-metal race bearing. SecureBond is a micro-etch surface preparation process that strengthens the tri-metal structural integrity. SecureBond reduces the likelihood of catastrophic failure due to delamination of one layer from the other under extreme load conditions or metal–to-metal contact.\u003c\/p\u003e \u003ch4\u003e \u003c\/h4\u003e\u003cbr\u003e\u003cbr\u003eCheck your bearing size using our fitment calculator \u003ca href=\"http:\/\/kingracebearings.com\/catalog\/\"\u003ehere\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ciframe src=\"\/\/www.youtube.com\/embed\/_pSQhdgFum8\" width=\"560\" height=\"314\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ciframe src=\"\/\/www.youtube.com\/embed\/WNeARnFSiRQ\" width=\"560\" height=\"314\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"King Engine Bearings","offers":[{"title":"Default Title","offer_id":52027671609636,"sku":"BJDV_MB637XP","price":342.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0671\/6801\/0532\/files\/ShowProductImage_719d1d77-1586-4800-affa-d11af6c7e500.jpg?v=1771540515","url":"https:\/\/autohousesupply.com\/products\/king-engine-bearings-main-bearing-setmb-637xp","provider":"AutoHouseSupply","version":"1.0","type":"link"}
