Molded brass bushings

Brass and bronze bushings are one of the most common parts of sliding units in many devices and mechanisms. Due to the copper and zinc content of brass, the coefficient of friction against steel in the presence of lubrication is very low. This unique property of brass has led to widespread use as anti-friction bushings.

      The main method of manufacturing brass bushings is the turning of cylindrical metal blanks (circles, rods), which allows you to quickly and accurately give the desired shape to the product.

      For the manufacture of bushings of large diameters, the centrifugal casting method is used - it allows you to get a casting with dimensions as close as possible to the part and minimizes the cost of processing by a turner during processing, but this requires special casting equipment and a mold for casting.

     Hot stamping of bushings gives an even greater effect - in addition to obtaining a blank of the required shape, this method densifies the metal and eliminates the possibility of pores, cracks, etc. appearing in it. Also, hot stamping makes it possible to produce bushings that cannot be produced using turning alone (with edges, protrusions, grooves, etc.). To carry out the hot stamping process, as well as for centrifugal casting, it is required to make a special mold (the so-called matrix). It is this production method that is used by STA for the manufacture of bushings with a diameter of up to 100 mm from LS-59 brass.
