Compact hydraulic rotary joint

Compact hydraulic rotary joint is a product with small size, light weight, high pressure resistance, and high speed, suitable for use in equipment with limited space. There are various manufacturers of rotary joints in the market, and their prices vary greatly. The quality of each company’s products is also completely different. Why is there such a big difference in price?

There are many types of hydraulic rotary joints, and their production processes and procedures are different. Each joint manufacturer uses different materials, which is also the key reason for the different prices and quality of products produced by different manufacturers. Some manufacturers use O-rings on the inner surface of hydraulic slip rings, and the material is treated with ordinary 45 steel blackening. This type of product is prone to leakage when under pressure, and the quality is relatively poor. The manufacturing cost is low and naturally cheap. Some manufacturers use ordinary Glay rings for sealing, 45 steel electroplating treatment, which is the most common process, and the service life is not too long. The price is at an average level, SD adopts high-speed steel vacuum treatment, surface alloy layer, high wear resistance, corrosion resistance, and high pressure resistance. The interior uses imported polymer metal powder synthetic materials, which have ultra-high wear resistance and a service life of up to 8 years. Of course, the manufacturing cost is high, and the selling price is naturally higher than that of ordinary manufacturers. There is no such thing as a high price for no reason. The determination of the selling price comes from the cost of the product. High quality rotary joint products can make users feel at ease and comfortable without maintenance. The product often needs maintenance, but in fact, the maintenance cost is higher than the ordering cost. Therefore, when choosing rotary joints, we cannot only look at the price, but also need to pay attention to the quality of rotary joints, especially the quality of hydraulic high-pressure rotary joint products. We should pay more attention to it because the product quality is poor. There may be issues with usage alone, We need to pay more attention to safety. If high-voltage products burst, the consequences can be quite serious, which will seriously damage the safety of equipment personnel. Therefore, when choosing a rotary joint manufacturer, if it is used for a long time, it is not recommended to replace it because it is cheap. The product is stable and can quickly improve the efficiency of the equipment, greatly reducing maintenance costs.
