Key features

Adopt centrifugal-cast aluminum-bronze alloy with good toughness and shock resistance, suitable for heavy-impact working conditions at roadheader underground hinge positions.

Lubrication storage grooves machined on inner wall retain grease effectively, improve sliding friction between pin and bushing and reduce dry-grinding risk.

Excellent anti -seizure performance reduces seizing shaft and scoring between pin and bushing under heavy-load reciprocating swing, prolonging service life of hinge pairs.

Product Q&A

Q:What underground conditions lead to shaft seizing and scoring between bushing and pin?

Continuous heavy-load rock-breaking impact and lubrication failure raise local temperature and cause metal seizing. Avoid long-time grease-starred operation under heavy load.

Q:Why does obvious play and noise occur at hinge joint during operation?

Long-term inner-wall wear enlarges fitting clearance and creates play and noise under swing impact. Continuous operation with excessive clearance will accelerate pin wear.

Q:What influences do muddy-wet roadways bring to bushing?

Coal-mud and moisture invade clearance, corrode alloy surface and dilute grease to break lubrication film. Protect hinge joints from dust and replenish grease timely.
