QLC™ Coated Engine Bearings: Built for Bearing Excellence Under Extreme Pressure

At Rocketman Race Coatings, our QLC™-coated engine bearings—available for rods, mains, and more—transform standard components into self-lubricating powerhouses through a permanent, 0.5-1 micron chemical bond. Unlike surface-applied coatings that fail under heat, QLC™ integrates at the molecular level for lifelong performance. Here's how these features shine specifically for engine bearings in high-stakes racing:     

Ultra-Slick Surface That Enhances Under Load – The "Slicker" Effect for Bearing Supremacy     

QLC™ starts incredibly slick and becomes even slicker when pressure mounts, ideal for the intense sliding and rolling in engine bearings during high-G launches or sustained RPMs. This dynamic friction reduction cuts drag in rod and main bearings, minimizing energy loss and boosting oil flow for cooler operation and faster ETs. In NHRA drag applications or tractor pulling, QLC™-coated bearings ensure smoother crankshaft rotation, preventing binding under extreme mechanical stress.

Superior Oil Retention – Oleophilic Design for Instant Startup Protection and Extended Bearing Life

Unlike traditional materials that let oil wash away, QLC™ holds oil within the bearing surface itself, providing immediate lubrication from cold starts to redline. This oleophilic property eliminates oil starvation and micro-welding in critical areas like rod bearings during high-load shifts or main bearings under boost. For pullers and drag racers facing sudden torque spikes, this means drastically reduced wear, lower blow-by, and superior heat dissipation. An example is Lemke Motorsports—multiple-time Pro Pulling League champions who've leveraged similar tech for their $50,000 win at Farley, IA, this year—our bearings deliver race-proven reliability, keeping your engine protected lap after lap or pass after pass.

Much slicker than Moly with No Cracking, Peeling, or Ablation – Unrivaled Bearing Durability

QLC™ achieves a coefficient of friction much lower than Moly coatings, without the cracking, peeling, or ablation that plague others under thermal cycling in engines. Imbedded as an ultra-thin layer, it withstands the punishing environment of bearings in supercharged or turbocharged setups, lasting 2-10 times longer than competitors. While other coatings might delaminate in extreme racing events, QLC™'s permanent bond resists failure, ensuring your coated bearings—like those in high-horsepower pulling & drag engines—maintain integrity through national records and hard-fought wins.

Self-Lubricating Molecular Bond – A Permanent Thin-Film Lubricant for Bearing Innovation

QLC™ acts as its own lubricant, chemically interacting with the bearing substrate at the molecular level to form a seamless, thin film via high-pressure Force Altered Technology. This isn't a temporary spray—it's a transformed surface that sheds heat, reduces radiant temperatures, and enhances stability in oil galleys and bearing shells. For everything from mini-sprint mains to full-drag rod bearings, this nano-coating helps prevent scoring and galling. Refined through years of motorsports testing, QLC™ bearings from Rocketman Race Coatings your only choice.
