It measures 316mm across, 28mm thick, and 52mm tall, with a 6 x 108mm wheel bolt pattern. It's the straightforward, corrosion-resistant replacement for restoring solid everyday braking, sold as a single rotor.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the Hella 355118892, a vented one-piece disc brake rotor built from zinc-coated gray cast iron. It measures 316 millimeters across the outside diameter, runs 28 millimeters thick through the friction band, and stands 52 millimeters tall from the mounting face to the hat. The wheel bolt pattern is 6 x 108 millimeters. It's sold as a single rotor, so if you're doing a full axle you'll want two.\u003c\/p\u003e\n\u003cp\u003eLet's talk about why the vented design matters. A vented rotor has cooling vanes cast between the two friction faces, and those vanes pump air through the core every time the wheel spins. That airflow pulls heat out of the rotor after hard or repeated stops, which keeps the pad and rotor closer to their happy operating range. When a rotor overheats, braking gets soft and inconsistent. The vented core is what keeps that from happening on grades, towing days, and stop-and-go traffic.\u003c\/p\u003e\n\u003cp\u003eThe one-piece design means the hat and the friction ring are cast as a single unit. Nothing to assemble, nothing to torque together. You slide it on, seat it against the hub, and you're most of the way home. It's the straightforward setup most drivers want when they're doing a brake job in the driveway on a weekend.\u003c\/p\u003e\n\u003cp\u003eGray cast iron is the material almost every quality rotor uses, and for good reason. It handles heat well, it wears predictably, and it gives the pad a consistent surface to bite into. Hella finishes this one with a zinc coating, which is the part worth calling out. Bare cast iron flash-rusts the moment it sees moisture. You've seen it, that orange film on a rotor that sat in the rain overnight. The zinc coating fights that on the hat, the vanes, and the edges where surface rust looks ugly and can spread. The friction faces wear clean after the first few stops as the pads bed in, so you get corrosion protection where you want it and a clean braking surface where you need it.\u003c\/p\u003e\n\u003cp\u003eFitment comes down to two things: the 6 x 108 millimeter bolt pattern and the rotor's dimensions. The 316 millimeter diameter, 28 millimeter thickness, and 52 millimeter height all need to match what came off your vehicle. Before you order, we always tell folks to pull the old rotor and measure, or cross-check the 355118892 part number against your vehicle's application. A rotor that's a hair off on diameter or hat height won't clear the caliper or seat right, and that's a headache you can avoid with five minutes and a caliper.\u003c\/p\u003e\n\u003cp\u003eA few honest install notes from doing a lot of these. Replace rotors as an axle pair whenever you can. Braking is balanced side to side, and a fresh rotor paired with a worn one on the other corner pulls unevenly. Fit new pads at the same time so both surfaces bed in together. And take ten minutes to bed the brakes in after the install, a series of moderate stops from moderate speed, so the pad material transfers evenly across the friction face. Do that and this rotor will run quiet and true.\u003c\/p\u003e\n\u003cp\u003eHella has been making vehicle components for decades, and this rotor is built to that same fit-and-forget standard. It's machined to spec so runout stays low out of the box, which matters more than people think. Excess runout is what causes that pulsing you feel through the pedal a few thousand miles down the road. Start with a true rotor and a clean, rust-free hub mating surface, and you sidestep most of the comebacks that make a brake job feel like it didn't take.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone replacing a worn, warped, or rusted-through rotor on a vehicle running the 6 x 108 pattern and these dimensions. It's a direct-replacement style rotor, not a drilled or slotted performance piece, so it's the sensible choice for daily driving, hauling, and normal road use. If you're chasing track-day parts, that's a different animal. For getting your brakes back to solid, predictable, everyday stopping power, this is exactly the kind of part you want.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e316mm outside diameter delivers a large swept area for confident everyday stopping power\u003c\/li\u003e\n  \u003cli\u003e28mm nominal thickness with a vented core pumps air through the rotor to shed heat and resist brake fade\u003c\/li\u003e\n  \u003cli\u003eOne-piece design casts the hat and friction ring as a single unit for a simple bolt-on install\u003c\/li\u003e\n  \u003cli\u003e6 x 108 millimeter wheel bolt pattern for direct fitment on matching vehicles\u003c\/li\u003e\n  \u003cli\u003eZinc coating over gray cast iron fights surface rust on the hat, vanes, and edges\u003c\/li\u003e\n  \u003cli\u003eGray cast iron friction surface wears predictably and gives the pad a consistent bite\u003c\/li\u003e\n  \u003cli\u003e52mm overall height from mounting face to hat, matched to OE-style dimensions\u003c\/li\u003e\n  \u003cli\u003eSold as a single rotor, so order two for a full axle\u003c\/li\u003e\n  \u003cli\u003eDirect-replacement style built for daily driving and hauling, not a drilled or slotted performance rotor\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat are the dimensions of the Hella 355118892 rotor?\u003c\/summary\u003e\n    \u003cp\u003eIt's 316 millimeters in outside diameter, 28 millimeters in nominal thickness, and 52 millimeters in overall height.
