914901205 Buffering RingXCMG XDE130 Electric driving dump truck spare parts

The 914901205 buffering ring solves problems such as ring aging, buffer attenuation, pressure cracking, end-face oil leakage, rebound lag, pressure leakage during bonding, friction noise, deformation collapse, assembly detachment, and damping failure. It is suitable for replacing old buffer rings, maintaining hydraulic cylinders, original equipment manufacturer (OEM) parts, cylinder noise reduction, and repairing end-buffer failures. Made of oil-resistant polymer-modified substrate with a dense ring structure, it offers strong energy absorption, pressure and extrusion resistance, oil and temperature resistance, and a tight seal, making it suitable for high-frequency extension and retraction, high-pressure impact, and reciprocating extrusion hydraulic conditions in engineering machinery cylinders.

Core technical parameters:

– Product Model: 914901205
– Product Name: Buffering Ring
– Material specifications: Modified pressure-resistant polymer material, with dense cross-linking treatment, not easy to crack or age under high pressure extrusion.
– Processing technology: Original factory ring precision machining and shaping, dimensional tolerance calibration, and direct installation and adaptation of the original car cylinder end slot without damage.
– Performance and operating condition compatibility: Rated buffer pressure meets standards, absorbs energy and stabilizes pressure, and is compatible with the end buffer system of the hydraulic cylinder of the whole machine.
– Structural features: Fully enclosed damping ring structure, uniform force relief and shock absorption, eliminating the failure of pressure relief due to impact at the end of the cylinder.

This product undergoes high-pressure extrusion, reciprocating buffering, leak testing, and original factory quality inspection to ensure compatibility with the original machine slot. It meets the original factory installation standards and is ready to use immediately after installation. It buffers and offsets the impact force at the cylinder’s extension and retraction ends, fits snugly to the slot to prevent oil pressure leakage, and is compatible with the original factory cylinder slot for assembly, ensuring stable operation during cylinder start-up and shutdown.
