Suitable Model

CH895

Application

Used for vibration damping, cushioning and elastic overload compensation of the crusher, absorbing operating vibration and reducing structural fatigue to protect the frame and foundation

Installation Notes

1. During installation, avoid eccentric load and shear; compression/tension must not exceed design travel; 2. Rubber parts must avoid contact with grease and solvents; 3. When replacing as a set, ensure consistent stiffness of all parts

FAQ

What are the signs and causes of spring failure?
Signs: permanent deformation (shortened free length), fracture, stiffness loss, surface corrosion and cracks. Causes: overload, fatigue, corrosive environment, improper installation (eccentric loading), and material defects. Prevention: avoid over-travel compression, regularly check free length changes, and use anti-corrosion coating or stainless steel in corrosive environments.
How to evaluate whether a shock absorber needs replacement?
Replace the shock absorber when oil leakage, rubber cracking and aging, significantly reduced damping (slow or no rebound after pressing), or mounting seat cracks occur; normal service life is 3-5 years or 8000-12000 working hours; replace in pairs to ensure consistent damping.
What are the storage and usage precautions for rubber parts?
Store at 5-25°C with relative humidity ≤65%, avoid direct sunlight and ozone environment, keep away from heat sources and grease; shelf life is typically 2-3 years from the production date; avoid sharp objects and use special tools during installation; direct hammering is prohibited; different rubber materials (NBR/FKM/EPDM) differ in temperature and oil resistance and must not be mixed.
