JZP-13.5-SC Rubber Shock Absorber Creep Resistant Metal-to-Rubber Bonded 13.5kg Cyclic Loading Endurance Mount

JZP-13.5-SC Rubber Shock Absorber: 13.5 kg Friction Damping Mount for Continuous Cyclic Loading

Direct answer: The JZP-13.5-SC is a 60 mm diameter rubber-to-metal vibration isolator rated at 13.5 kg per mounting point, with a resonant frequency of 41.5±5 Hz, a damping ratio of 0.13 or above and static deflection held to 0.3 mm or less. It is specified for equipment that repeats load cycles for years rather than months.

What does friction damping contribute in this design?

Energy is converted into low-grade heat by internal friction inside the elastomer rather than by an external damper. Damping of at least 0.13 shortens settling time after start-up, shutdown or a shock input, and it limits the amplification that occurs when a disturbance sweeps through the 41.5±5 Hz resonance band. Equipment that runs through frequent speed changes sees the benefit as reduced peak displacement rather than as a change in steady-state transmissibility.

Is the part suitable for outdoor and wet locations?

The elastomer resists chemical agents, seawater, ozone and ultraviolet exposure, and the operating window of -45 °C to +65 °C covers both climate-controlled cabinets and exposed frames. Where sustained direct sunlight is expected, a simple shield over the element extends the cosmetic life of the rubber without altering performance.

What proof of shock capability is available?

The design is qualified with 100G impact testing over 12 cycles, which is well above the transient levels normally seen in transport and handling. Combined with the rated service life of 8 years, this gives maintenance planners a basis for setting replacement intervals instead of reacting to failures.
