OST 1 11119-73 Bushings for pressing in
Bushes according to OST 1 11119-73 – are made of steel 30KhGSA.
Description of product design features
Installation bushings must be produced in four versions, depending on the maximum deviations for the inner diameter:
- performance 1 – by H7;
- performance 2 – by H9;
- version 3 – by H12;
- performance 4 – by M7.
The bushing is made of structural alloyed carbon
steel – 30ХГСА.
At the circumference of the butt B of the bushings, two radial marks with a depth of 0.2 – 0.3 mm.
Cadmium (Kd3.phos.oks.) and zinc (Ts3.fos.oks.) coating of bushings for pressing is carried out in our own electroplating shop.
An example of the name and designation of a sleeve for pressing-in version 1 with dimensions d = 8 mm, D = 10 mm and L = 25 mm made of steel 30KhGSA, coated with Kd3.phos.ox.:

Product applications
The most popular bushings are in mechanical engineering, automotive and aircraft manufacturing. Without them, the work of transport and production machines will simply be impossible. After all, I am located between two moving elements, they are reliable protection for each of them. Therefore, the bushings themselves must be plastic and durable.
The use of bushings allows during the operation of a mechanism to carry out a planned replacement of the element itself. At the same time, if the operating conditions and regular maintenance are observed, the replacement of expensive parts of the product or its body will not be required. The bushings themselves are often consumables that allow the operation of large components and assemblies.
