description

The DH225‑9 Pin Cover is manufactured from high‑density toughened rubber‑plastic composite material, optimized for medium‑large excavator vibration and impact characteristics. It maintains good elasticity and tear resistance under continuous impact load, and will not harden rapidly under outdoor working conditions. Anti‑UV and anti‑aging ingredients are added into material formula, and surface is treated with anti‑fouling and anti‑corrosion process, adapting to sun exposure, rain erosion and mud‑sand impact on various construction sites. Adopting integral wrapping structure, it fully covers the matching gap between pin shaft and bushing, keeps internal lubricating grease clean, avoids dry friction and abnormal wear caused by foreign‑matter intrusion. All finished products pass dimensional inspection and elasticity fatigue test, with stable quality and good interchangeability, which is an essential wearing protective part for daily maintenance of Doosan DH225‑9 excavator.

FAQ

Q1: Is this pin cover dedicated for DH225‑9?
A: Yes, this product is specially developed for Doosan DH225‑9 22‑ton medium‑large excavator, with exclusive matching dimension, cannot be interchanged with other tonnage models directly.
Q2: Can it be used on DH225‑7?
A: Not directly recommended. Please verify opening and clamping size before cross‑model installation to avoid poor fitting or falling‑off.
Q3: When shall we replace the DH225‑9 pin cover?
A: It needs timely replacement when showing hardening, cracking, deformation, loose clamping, falling‑off or losing elasticity.
Q4: Does installation of DH225‑9 pin cover need modification or debugging?
A: No modification or debugging required. It is snap‑on type, plug‑and‑play, tight fit after installation.
Q5: How to extend service life of DH225‑9 pin cover?
A: Regularly clean surface sediment, perform normal grease filling maintenance for pin‑shaft position, reduce friction loss, so as to prolong service life of pin‑cover and pin‑shaft assembly.
