5. FAQ
Q: What prominent practical advantages does HNBR rubber own compared with conventional ordinary NBR rubber?
A: HNBR features exceptional damp ageing resistance and anti-hydrolysis capability, maintaining stable sealing performance after long-term exposure to moisture-contaminated hydraulic oil in damp outdoor mining and wet mud construction sites.

Q: At which detailed fixed cylinder positions are HNBR rubber O-rings commonly mounted?
A: HNBR small rubber fittings are used for static sealing on cylinder end cover mating surfaces and threaded connector gaps of hydraulic pipelines where slow invisible fluid seepage easily occurs.
Q: What beneficial optimization does phenolic impregnated polyester fabric wear ring bring to piston reciprocating movement?
A: It effectively limits piston lateral offset and side shake during boom movement, keeps piston running concentrically inside cylinder bore and cuts down persistent frictional scratch between piston outer wall and cylinder inner tubing.
Q: Are all spare parts produced strictly following original OEM dimension specifications?
A: Every sealing accessory is manufactured referring to factory original engineering drawings to achieve perfect direct replacement without field size trimming or manual fitting adjustment.
Q: Do on-site service technicians need to cut or polish seal edges to match installation grooves?
A: No cutting, sanding or any manual dimension modification is required at all; new seals can be directly fitted once worn original seals are disassembled and removed.
