As the reliable utility trailer & boat trailer parts manufacturer in China, we have a large stock of trailer idler hubs. We can produce trailer idler hub with 4, 5, 6, 8 lugs. We export trailer brake hubs & drums in a wide variety of sizes and lug patterns. And we can produce it according to customer's requests, drawings or samples.
All of Qichang's hubs are manufactured from high grade ductile iron to give maximum achievable strength.
The capacity of a hub is dependent on the size of wheel bearings fitted and such dimensional limits such as flange diameter and the available hole in the wheel to which it is fitted (on the hub this is the hub outer boss dimension).
Actually, it’s very important to ascertain the wheel bearing type, wheel drilling pattern and the excepted total load when you choose the suitable hub/rotors. A full kit completes with bearings, marine seal, dust cap, plated studs & nuts.

The production process of brake hub blanks is casting. The main raw materials are iron, scrap and iron, and some alloys, such as Cu and Cr, are brittle gray cast iron. The wear resistance is very good and the hardness is about HB200. The brake hub is machined for thin-walled parts. The tolerance control of shape and position is always a difficult problem for many factories in mass production, such as round jump, cylindricity, parallelism, tolerance of brake drum small holes and so on. In addition, the surface roughness is high, the general surface finish is within Ra1.6, and many manufacturers are now using the number. The control lathe is used to process the brake hub at high speed, so the tool material processing brake hub must ensure that the tool has good machining performance, while the hardness, wear resistance, toughness, impact resistance performance and so on are excellent tool materials, and also have longer life life.
