This 6 Bolt on 5.5 inch bolt pattern brake drum hub is generally used on medium-duty land trailers like utility or cargo trailers in a drum brake system. This painted brake drum hub is compatible with 5,200 - 6,000 lb capacity axles with a #42 spindle, using a 1 1/4” (outer) x 1 3/4” (inner) bearing combination. This particular listing for this brake drum comes with bearings, seals, and a cotter key needed to install the drum hub onto a 6,000 lb axle.
The kit includes inner bearing #25580 with an inner diameter of 1 3/4", outer bearing #15123 with inner diameter of 1 1/4", one zinc-plated cotter key to secure the castle nut once it has been properly installed, and two #42 spindle seals with inner diameters of 2 1/4" and 2 1/8". You will only need to use one of the seals and it gets installed on the back of the drum hub, so measure the wear sleeve on your spindle and previous seal and use only the correct sized seal when you are installing the drum.
This 6 Bolt brake drum hub is painted black and is commonly seen on utility trailers with Electric Drum Brakes or on some Freshwater Boat Trailers with Hydraulic Drum Brakes. You would not usually see this type of braking system in saltwater. If you need to replace the other parts of your Trailer Brakes, like the Backing Plate, or Electric Cluster, you can buy those separately. This is the Drum Hub with a bearing kit, so if you need Lug Nuts, bearing buddies, or Dust Caps you can always add them to your cart.
