It runs 330mm across with a 22mm nominal thickness, a 67mm hub bore, and a 7 x 112mm bolt pattern. Sold as a single rotor, it's a straight replacement that sheds heat and shrugs off surface rust.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Hella 355113232 is a vented, one-piece disc brake rotor cast from zinc-coated gray cast iron. It measures 330mm across the outside diameter with a 22mm nominal thickness, a 67mm hub bore, and a 7 x 112mm wheel bolt pattern. It ships as a single rotor, so it's a straight replacement for the axle position it's spec'd to fit.\u003c\/p\u003e\n\u003cp\u003eHere's what the vented part buys you. A vented rotor has internal cooling vanes cast between the two friction faces, and those vanes pull air through the rotor as the wheel spins. That airflow carries heat away from the braking surface. Heat is what kills brake performance. When a rotor soaks up more of it than it can shed, you get fade, that soft pedal feeling on a long downhill or after a few hard stops in a row. At 330mm across with 22mm of thickness to work with, this rotor has real mass and swept area to move that heat out.\u003c\/p\u003e\n\u003cp\u003eThe one-piece design means the hat, the center section that bolts to the hub, and the friction ring are cast as a single unit. There's no separate hardware between the two sections, and it bolts up the way the factory rotor did. Gray cast iron is the standard material for daily-driver rotors because it takes repeated heat cycling well and machines cleanly. The zinc coating is the part worth calling out. Bare cast iron flash-rusts almost overnight, especially on the hat and the outer edges the pad never touches. The zinc plating keeps that surface rust off, so the rotor stays clean behind an open wheel and the non-swept areas don't turn orange after the first rain.\u003c\/p\u003e\n\u003cp\u003eFitment comes down to a few numbers. The 7 x 112mm bolt pattern, the 67mm hub bore, and the 330mm diameter all have to match what your vehicle and caliper expect. The 62.80mm height sets how deep the hat sits, which is what positions the friction ring in the caliper, so that figure matters as much as the diameter. Check the part number on your current rotor or measure the old one before you order. The 330mm diameter especially has to clear the inside of your wheel and line up with the caliper bracket, so this isn't a part you want to guess at. If you're not sure, cross-reference 355113232 against your application first.\u003c\/p\u003e\n\u003cp\u003eOne habit worth keeping is replacing rotors in axle sets. This SKU is a single rotor, so if you're doing both corners, order two. Braking is balanced side to side, and a fresh rotor paired with a worn one on the same axle can make the car pull under braking. New rotors also want a proper bed-in. Fit new pads at the same time, then run a series of moderate stops from moderate speed to lay an even layer of pad material across the friction face before you lean on the brakes hard. Skip that step and you can end up with uneven deposits and a pulsing pedal down the road.\u003c\/p\u003e\n\u003cp\u003eRotors don't last forever. This one starts at 22mm nominal thickness, and once wear or machining takes it below the discard spec for your application, it gets replaced rather than resurfaced. If you've got vibration through the pedal, a deeply scored surface, or a lip at the outer edge you can catch a fingernail on, it's time. A rotor that's still within spec can sometimes be turned on a lathe, but a fresh one runs truer and lasts longer than a machined one, which is why a lot of shops just replace them. The Hella 355113232 gives you a direct replacement with the corrosion protection already built in. Grab the matching pads and hardware while you're in there and you'll do the job once.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eVented design with internal cooling vanes cast between the friction faces for better heat dissipation and less brake fade under repeated hard stops\u003c\/li\u003e\n  \u003cli\u003e330mm outside diameter delivers a large swept area for strong, consistent braking\u003c\/li\u003e\n  \u003cli\u003e22mm nominal thickness gives usable material and a defined minimum-thickness service life\u003c\/li\u003e\n  \u003cli\u003e7 x 112mm wheel bolt pattern for a direct fit to the matching axle application\u003c\/li\u003e\n  \u003cli\u003e67mm hub bore centers the rotor accurately on the hub for smooth, vibration-free rotation\u003c\/li\u003e\n  \u003cli\u003eOne-piece cast design bolts up like the factory rotor with no separate hat hardware\u003c\/li\u003e\n  \u003cli\u003eZinc-coated gray cast iron resists surface rust on the hat and non-swept edges\u003c\/li\u003e\n  \u003cli\u003e62.80mm overall height matched to the original rotor's hat depth\u003c\/li\u003e\n  \u003cli\u003eSold as a single rotor, so order two to replace a full axle set\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 355113232 rotor?\u003c\/summary\u003e\n    \u003cp\u003eIt runs 330mm across the outside diameter, 22mm nominal thickness, 62.80mm overall height, and a 67mm hub bore.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is the wheel bolt pattern?\u003c\/summary\u003e\n    \u003cp\u003e7 x 112mm.
