RITO Genuine Part Dust Seal ZX870 ZX670 Excavator Dust Oil Seal for Hitachi

Excavator sealing failures often begin with gradual loss of barrier efficiency at the swing and joint interface, where continuous rotation, pressure, and external contamination interact. The RITO dust seal for ZX670 / ZX870 is engineered to control this exposure zone, limiting fine particle intrusion while maintaining stable sealing contact during long operating cycles.

FAQ


QWhat is the real cause of dust seal failure in excavators?
A: It is usually not sudden damage, but long-term abrasion from fine sand and pressure cycling that gradually reduces sealing tension.
 
QHow can field operators identify seal degradation early?
A: Signs include fine dust accumulation near joints, grease contamination, or slightly increased swing resistance.
 
QWhat matters most during replacement?
A: Correct seating position and ensuring the sealing lip is not twisted during installation are critical.
 
Q: Can this seal be used in mining conditions?
A: Yes, it is designed for high-dust and high-impact working environments typical in mining operations.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
