Wide range of plain bearings in all variations and solutions

ttv sliding bearing technology is used in a wide range of applications in drive technology, machine and commercial vehicle construction as well as in the road construction and agricultural industries. Whether in wind turbines or power tools, our plain bearing technology ensures the reliability and functionality of your machines. It is characterised by the highest technical standard and state-of-the-art production processes. In addition to a large range of plain bearings available from stock, we are increasingly focusing on customer-specific solutions.

As a specialist in sliding bearing technology, we know: Wherever heavy loads are to be moved with low friction, resilient, high-quality plain bearings are needed. We are increasingly meeting these continuously increasing requirements with individually developed products from our Engineering Solutions department. 

All ttv products naturally meet the technical and economic requirements of leading industrial companies. Individual features are optimally implemented by us and secure your application with the highest reliability.

The plain bearings are installed by pressing them into a machined housing "H7". 

Please note the following:

  • Creating an insertion bevel, cleaning and deburring the parts to be assembled
  • Lubricate the outer surface of the plain bearing before assembly
  • Check the axiality between the installation space and the centring axis of the plain bearing
  • if two slide bearings are required, they must be aligned
  • use a fitting mandrel of the appropriate size 

Assembly is carried out using hydraulic presses or mechanical machines. The maximum resistance (F) is shown in the following table:

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.

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.

Sliding bushings for all markets.

Whether in the agricultural machinery sector, the construction machinery sector, the forestry technology or drive technology sectors, the mechanical engineering sector, the automotive industry or the aerospace industry, our sliding bearings meet even the most demanding requirements of any industry. Wrapped sliding bearings, solid lubricant sliding bearings or turned solid sliding bearings are the best examples of the solutions we keep in stock.

Anyone looking for maximum performance for their products will find the perfect solution with our Engineering Solutions. With our customer-specific sliding bearings, we offer added value in all of the crucial product parameters.
