4200085 Original Excavator Rubber Pad for Hitachi EX200

Part number 4200085 is a genuine rubber pad produced by Hitachi Construction Machinery in Japan. A support chain (track link) system used for crawler excavators or bulldozers, serving as a sealing, buffering, or anti loosening gasket between hinge points such as chain links, pivot pins, or tensioning devices. Therefore, it is mainly suitable for crawler type super large excavators such as Hitachi EX200. Its universal model covers large models on the same platform with the same support chain structure.

This product is a black ring shaped rubber pad, which is made of oil resistant, wear-resistant and anti-aging synthetic rubber. Its core function is to form an elastic seal between the metal hinge points of the support chain, preventing sediment intrusion and lubricant leakage, while buffering impact and reducing direct friction and noise between metals. The original parts ensure that they can maintain their elasticity and sealing performance for a long time in extreme heavy load, impact, and oil pollution environments in mines. The "CBABBC" on the label is the production batch number.

Inspection cycle: Every 250 working hours, when inspecting the support chain, pay attention to whether there is any abnormal leakage or looseness at the hinge point. Replacement timing: This gasket is a disposable seal and must be replaced after disassembly. If hardening, cracking, permanent deformation or loss of elasticity is found during daily inspection, it must be replaced immediately. Caution: Do not reuse; When storing, it is necessary to avoid light and moisture to prevent deformation caused by compression.
