Sliding bearings: In the engine block, these play a prominent role. The main task in a bearing's life: to generate and support load transmitting oil films under even the most extreme conditions. An engine will only keep running smoothly if the lubrication is right. If not, you risk damage to connecting rod bearings or crankshaft bearings. Or worse: damage to the crankshaft. That's why you can confidently choose ACL, one of our quality bearing brands. ACL is an Australian company (Tasmania) that has been researching 'precision engine bearings' and 'performance engine bearings' for 70 years.
ACL is first and foremost a well-known supplier of parts to the automotive industry. What certainly counts: ACL's years of experience in all fast sports, such as the Australian V8 SupercarTM Championship, drag racing, speedway, drifting and rallying.
Gradually, the rest of the world discovered: there are engineers and product developers at ACL who really know their stuff. For more than 20 years, for instance, ACL has seen Wilmink as an important partner for Europe (with a clear understanding of the business), with brands such as ACL Duraglide and ACL Race Series in its range. To give you an idea: in the ACL Race Series alone, you can choose from 250 different engine types, the American muscle cars and race cars, but also the Japanese, Korean and European applications.
At ACL, they are constantly working to improve the operation and service life of bearings. A bearing consists of ultra-thin layers in different thicknesses with different tasks. Together these act to maximise bearing toughness. Among others are crafted alloys of; copper, nickel, aluminium, lead and tin. How exactly, that is the secret of ACL. They put it this way: "If you place demands on your engine, demand the best."
Among other things, ACL uses its partner company Calico's unique coating. This is a unique 'dry film' coating thanks to the finishing layer of minimal thickness (less than a tenth of a millimetre). It moderates interaction between shaft and bearing improving system durability under extreme conditions.
At ACL, they think of everything. Including the sometimes tedious task that a race team's maintenance team has to face. Where everything has to be right, because every second counts. For those places that are difficult to reach with standard measuring instruments, there is the Flexigauge, a thin plastic strip made with extreme precision, with which you can properly check the clearance control. Available in four sizes, it allows you to check all variants of clearance in engine blocks.
Thanks to proven performance, it has become a popular engine in the performance world: the Chevrolet LS V8 engine. Firstly, because it is a block that is easy to tune. Moreover, the Chevrolet LS is compact, exceptionally powerful, reliable, relatively affordable and parts are always readily available.
