Sliding Bushings

ttv sliding bearing technology is used in a variety of applications in the fields of drive technology and mechanical engineering as well as the commercial vehicle manufacturing industry, road-building and agricultural industries. Whether for use in wind power stations or power tools, our sliding bushing technology ensures that your machinery works reliably and efficiently. Our bushings are characterised by their state-of-the-art technology and the ultra-modern production processes we employ to manufacture them.

As a specialist in the field of sliding bushing technology, we know that high-quality and resilient sliding bushings are required whenever heavy loads with low levels of friction need to be moved. Our products meet all technological and economic requirements of modern industry. We implement customised features in the most effective way possible, ensuring that you can use our products with all your applications.


Sliding bushings are installed by being pressed into a machined housing "H7".

Please note the following:

  • Create an insertion bevel at an angle, and clean and deburr the parts to be assembled
  • Lubricate the outer surface of the sliding bushing prior to installation
  • Check the axiality between the installation space and the centring axis of the sliding bushing
  • If two sliding bushings are required, these must be aligned
  • Use a counter mandrel with suitable dimensions



The installation is carried out using hydraulic presses or mechanical machinery.
The maximum resistance (F) is shown in the following tables:

Strip thickness

1 mm: F = 300 N × L         1,5 mm: F = 500 N × L         2 mm: F = 700       N × L 2,5 mm: F = 900 N × L


For sliding bushings with a diameter < 55 mm, it is recommended to use an installation ring with a diameter of 0.3–0.4 mm.

Inspections and checks

The method used to check the strip thickness consists of checking the inner and outer diameter dimensions. The diameters must not be measured again before pressing in the sliding bushing, as this causes inaccurate measurements. The ISO 3547 standard (replacement for DIN 1494) describes the applicable method of measuring the diameter.

External diameter, test A

The testing equipment must comply with the ISO 3547 standard. The device consists of two halves, into which the sliding bearing is inserted and then clamped in place. During the tests, the two halves are pressurised and checked to see how far the sliding bushing yields. If the deviation "Z" is confirmed to be within a certain range, then the external diameter can be classed as correct.

Inner diameter, test C

The sliding bushing is pressed into an appropriate bore with a diameter tolerance as per "H7". Once it has been pressed in, the inner diameter can be checked using suitable measuring tools.
