Five reasons why you should use iglidur® plain bearings in motor vehicles

Noise reduction with iglidur plain bearings

What is Buzz, Squeak and Rattle (BSR)?

BSR are all noises that are produced by components and assemblies in the motor vehicle. BSR testing, also called a noise and rattle test, is an acoustic method from the automotive industry and is used to measure the volume of these noises. A realistic situation with corresponding vibrations is simulated and the volume of the noise is then measured. The technical challenge for the vehicle and component engineers is to identify the 'noisy' components and replace them with a quieter solution wherever possible.
 
The expectations of the OEMs in this context are increasing continually. In the case of alternative drives such as the hybrid or electric motor, the noise of the drive is reduced, as a result of which noises inside the vehicle are masked to a much lesser extent by a loud combustion engine. At the same time, it is becoming quieter and quieter inside motor vehicles.

How do iglidur plain bearings reduce noise?

Noises always arise where components interact with each other, in other words where friction occurs. With the tribologically optimised high-performance polymers from igus, you achieve an especially low coefficient of friction and therefore a quiet application. Whether in vehicle seats, hinges or actuators, the variety of applications for our iglidur plain bearings inside vehicles is great.
 
Polymer is characterised by the fact that, unlike metal, it has a damping effect. In applications involving severe vibrational stress, a polymer bearing solution helps to reduce noise inside motor vehicles. The range of materials developed by igus includes materials that have especially good damping properties.

This is how self-calibration works

Step 1

Roughly stamped mount or roughly stamped collared groove with a H10 or H11 nominal size range.

This is how self-calibration works

Step 2

An iglidur plain bearing with sliding fit is mounted in the hole or in the collared groove.

Step 3

Pin or rivet with cap is fitted in the bearing point.

Step 4

CDC (cathodic dip coating) is carried out with the fitted iglidur bearing and with the pin or rivet.

Step 5

The bearing point is dried. Due to the effect of heat, the iglidur plain bearings calibrates itself in the bearing point. Suitable for up to 220°C and a maximum drying duration of 60 minutes.

Step 6

The result: low-clearance bearing support in spite of holes and pins with large tolerance.
