JGD-D1 type rubber shear isolatorDetailed product description：

JGD-D1 rubber shear isolator is composed of inner and outer steel sleeves and synthetic rubber in the middle, which is vulcanized into a hollow cone shape. The rubber part is subjected to shear force, and the rubber shear isolator has a large deformation range and low natural frequency. The working temperature range of rubber shear isolators is -15 ℃ to+60 ℃, and the stiffness also changes with temperature changes; Damping ratio C/CC ≥ 0.07. JGD-D1 rubber shear isolator has good effects on active isolation of power machinery equipment such as water pumps, compressors, ventilators, generator sets, refrigerators, high-precision instruments, central air conditioning, and passive isolation and noise reduction of instruments and meters.
