Laboratory test

Rubber buffer

Silentflex laboratory · El Astillero, Spain

Compression test of a 951251 buffer in our laboratory: it reached 1146 kg with 28 mm of deflection and absorbed 16.9 J per cycle. In its curve sheet the natural frequency drops to 2.8 Hz: that is why it isolates as well as cushions.

Max. load tested
1,146kg
Max. deflection
27.98mm
Lowest natural frequency
2.8Hz
Energy absorbed per cycle
16.87J

Description

The rubber buffer is composed of two thick conical membranes joined together by a common axis and by a large central plate to create a kind of elastic washer.

The buffer is available in one of 3 configurations: 100% rubber; Rubber buffer with integrated metal fixing holes; Rubber buffer with integrated metal fixing holes, mounted on an oval or square metal plate.

The buffer is available in one of 3 configurations:

  1. 100% rubber;
  2. Rubber buffer with integrated metal fixing holes;
  3. Rubber buffer with integrated metal fixing holes, mounted on an oval or square metal plate.

Key features and benefits of Silentflex® Rubber buffers:

  • High axial elasticity;
  • Very low natural frequency (a few Hz);
  • Gradual stop on collisions, impacts or accidental overloads;
  • The elastomer intrinsic damping absorbs energy and is thus a significant advantage over a metal spring.
