BI-Trapez Bearing 20 mm


Bi-trapezoidal bearings insulate structure-borne sound and vibrations to a major extent. They are made of quality-monitored elastomer on the basis of the synthetic rubber ethylene-propylene-dien-mixed polymer (EPDM).


  • Simple processing
  • Allows the absorption of high loads
  • Parabolic load distribution
  • Static range of application (optimum) from 2.5 to 15 N/mm²
  • High vibration and structure-borne sound insulating values

Dimensioning for bearing class 2 in accordance with DIN 4141 Part 3:

  • Permissible mean compressive stress perm. σm: 5 N/mm²
  • Existing bearing spring deflection at perm. σ exist. Δt: 9,5 mm
  • Permissible horizontal shear strain perm. u: 8 mm

20 lfm incl. 3 tear lines
