Function of Hydraulic Shock Absorber:It enhances the productivity: As shock absorber can smoothly stop the impaction, therefore it greatly enhancesthe production efficiency of the machine and equipment in HF and high speed operation, It prolongs the mechanical life: As the buffer absorbs the impaction energy, it greatly reduces the impact and shockof kinetic object to the machine. It avoids the mechanical damage due to any impact I shock. It reduces the repaircost, prolongs the service life of the machine, brings about less after sale services.
◈Weight:0.455 KG
◈Stroke:40 mm
◈ Head of the buffer:Nylon
◈Working temperature:-10 ~+85 ℃
Attention
◈ It is strictly prohibited to knock or collide the shaft, which may easily lead to bending of the shaft. The surface of the shaft should not be covered with sewage or dirty oil, and the shaft must operate in a clean environment.Otherwise, it will increase the probability of product leakage and reduce the service life of the product.
◈It is strictly prohibited to spray paint on the pipe teeth and axis, otherwise it will affect the heat dissipation effect and oil leakage.
