High Elastic CAT B Series Rubber Buffer / Wear Plate Shock Absorbing Cushion For Medium Quarry Breaking
CAT B series rubber buffer wear plate, also known as shock damping cushion, is an elastic vibration-absorbing component installed behind the piston inside all CAT B medium hydraulic breakers from B12 to B90. Made of high-performance composite rubber instead of steel, it buffers harsh recoil shock from high-frequency striking, protects cylinder, through bolts and rear assemblies from rigid collision damage. Widely applied in municipal demolition, road renovation, landscaping excavation and medium quarry secondary rock crushing projects.
Produced with high-density PU, HNBR and fiber-reinforced rubber composite materials through integrated compression molding. This elastic material maintains stable resilience under continuous heavy impact, avoiding cracking, permanent deformation or aging failure under high hydraulic oil temperature and long working hours.
Precision moulding keeps standard OEM size for direct replacement without trimming. It evenly disperses reverse impact force, drastically cutting whole-machine vibration and working noise, effectively extending service life of metal wear parts, seal kits and connecting bolts.
Every batch of rubber buffer plates passes compression rebound test, high-temperature oil aging inspection and fatigue cycle test to match original equipment standards. Full model stock supports small retail maintenance orders and large bulk wholesale for construction contractors and machinery rental firms. Custom rubber hardness, thickness and anti-oil formula customization are available for global machinery maintenance factories and spare parts dealers.
