Supplier — AvekGlob Company — offers at affordable prices from the manufacturer brass bushings in a wide range of diameters, heights and wall thickness. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Brass bushings are produced from rolled brass pipes after being cut into size and the draft of the semi-finished product into a burt of the required dimensions. The starting blanks are obtained using crystallization processes, solid state and other ultra-high purification processes, for example, by sublimation. Brass bushes of low purity (with an allowable percentage of impurities of phosphorus, sulfur, bismuth and a number of other elements) are obtained from the secondary metal. These sleeves are cheaper, and can be used in products of low-use. Brass hubs imported production are produced in accordance with the technical requirements of ASTM B30−16, domestic brass bushings are manufactured in accordance with GOST 613−85.

Urgency of application

Brass bushes are used in such industries as hydropower, machine-tool construction, the production of automobile and tractor engines, mining, road construction machinery, aviation. The use of brass bushings improves frictional conditions in friction pairs, reduces specific energy costs and heat losses, increases the efficiency of devices.
