American 17, 35 castor products comparison and introduction

17 models and 35 models belong to the same series of heavy-duty casters. Taking the 6-inch iron core PU wheel as an example, the comparison is made from the aspects of structural design, bearing capacity and appearance characteristics.

Structural design: there is no substantial difference in the structural design of the two, both adopt the rotating structure combined with 51111 plane bearing +30203 conical bearing and welding support process structure, the thickness of the bottom plate is 7.8mm, the thickness of the support foot is 6mm; The differences are as follows: 1. The base plate size of the 17 models (115x101) is smaller than that of the 35 models (140X110); 2. 2. The appearance and outline size of the support are different, resulting in the different amount of support material. The weight of 17 types of active support is 0.87kg, and the weight of 35 types of active support is 1.28kg; 3, the matching wheel wheel width is different, 17 6-inch with the wheel width of 50mm, 35 6-inch with the wheel width of 52mm.

Carrying capacity: In terms of carrying capacity, the 35 model is better than the 17 model. The rated load of the 35 model is 850KG for the 6-inch model, and the rated load of the 17 model is 440KG for the 6-inch model. Carrying capacity is the most important performance index of casters, but it does not mean that the bigger the load, the better, because the problem of carrying capacity can be solved by increasing the number of wheels. Heavy trucks and cargo aircraft are typical engineering examples, so how to choose the load of wheels, but also to consider its economic value and practical.

Appearance features: 17 scaffolds are designed with circular arc, mild and beautiful appearance, and 35 scaffolds are designed with clear lines, resolute, simple and generous appearance, which can meet different aesthetic needs.

In short, the 35 models can be regarded as the upgraded version of the 17 models. At present, the two models are co-existing in the company. In the future, according to the market sales situation, we can consider adjusting them into one model.
