Product Description

Size and performance data of vibration damping pad

ModelBearing capacity(kg/cm²)Static deformation at vertical rated load(mm) Natural frequency at vertical rated load(Hz) Vertical limit static load(kg/cm²) Working temperature range(ºC)Damping ratio(C/Cc)
WJ-402~43kg/cm² h 4.2±0.513.8±130 -10~+40>0.06
WJ-604~65kg/cm² h 4.2±0.550
WJ-856~87kg/cm² h 3.5±0.517.5±170
WJ-908~109kg/cm² h 3.5±0.590

Selection method of vibration damping pad:

1. The area of a standard vibration damping pad is 24×46=1104cm², and the center area of connecting four convex platforms is 1 cm².
2. The area of vibration damping pad is decided according to the weight and working situation of equipment, it is cut based on a standard cushion block.
Area of vibration damping pad =Equipment weight /The bearing capacity of the selected vibration damping pad
For the equipment with shock and weight increase, the coefficient of overweight should be considered when choosing.

Application instance:

If a kind of equipment weighs 3500kg, the pivot shape is six drawing boards of φ12; because the levelness requirement of this equipment is high, the vibration and weight increase of the equipment at work shall be considered when choosing WJ-85; the weight of the equipment is appropriately increased by about 30% when calculating.
Bearing area = 3500 kg×1.3/7 kg/cm² = 650 cm²
Area of a single support = 650 cm²/6 ≈110 cm²
The vibration damping pad under the support must be exposed by 1cm margin, so the cushion block should be cut into 12×12 cm².

Scope of application:

Used for passive vibration isolation of punching machine, shearing machine, printing machinery and instruments.
