Product Overview\u003c\/h2\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eTrailer hubs sit behind the wheels where you cannot see or feel them, and a hub that is running hot looks exactly like one that is running fine. The Grundig Trailer Hub Temperature Monitoring System puts a wireless sensor at each hub and a receiver in the cab, so the temperature of every axle you are towing is on one screen while you drive.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eA sensor mounts with screws at the hub, beside the brake, reads temperature on its own, and reports by radio to the receiver — no wiring runs out to the sensors. Readings refresh every 6 seconds, and the kit takes one to ten sensors, so a single-axle trailer and a ten-wheel rig use the same system.\u003c\/p\u003e\n\u003c!-- II. Why Trailer Hub Temperature Matters --\u003e\n\u003ch2 style=\"font-size: 20px; font-weight: bold; letter-spacing: -0.2px; border-bottom: 2px solid #e2e8f0; padding-bottom: 10px; margin: 28px 0 16px;\"\u003eII. Why Trailer Hub Temperature Matters\u003c\/h2\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eEvery hub on a loaded trailer carries a share of the trailer's weight — hundreds of pounds on a light single-axle trailer, and more than a thousand on a heavy axle. The bearings and races under that load are where friction turns into heat, and a bearing that is dry, worn, or short on grease makes heat faster than the hub can shed it.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eThe order of events is what makes temperature useful: the heat comes first. A bearing on its way out warms up and keeps warming over miles before anything locks up. A rising number on a gauge gives you time to pull over and look at the hub, rather than finding out at the side of the road with a hub, brakes, and a tow to sort out.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eIt also covers ground that tire pressure monitoring cannot. A TPMS knows about the tire — its pressure and, on some systems, its air temperature. It has no way to tell you that the hub or the bearing behind that tire is cooking. Hub temperature is the reading that sits between the two.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 12px; font-size: 15px;\"\u003eMeasuring it is the simple part. A sensor reads temperature on its own, and sends the number by radio at 433.92 MHz to the receiver in the cab, where every position shows on one screen and refreshes every 6 seconds. The method holds up because it tracks the failure itself: friction makes heat, heat can be measured, and the increase shows up before the damage does.\u003c\/p\u003e\n\u003c!-- III.
