4. FAQ
Q: What materials is it made of, and why?

A:The seal has a multi-part construction. The outer metal shell is made of durable steel for structural strength and press-fit stability in the housing. The sealing lip is typically made of high-grade nitrile rubber (NBR) or polyurethane (PU), which offers excellent resistance to grease, water, and abrasion. Some versions also use a fabric-reinforced rubber layer for extra tear resistance under heavy loads. These materials are chosen because they withstand the constant pivoting motion, shock, and harsh operating conditions typical of construction machinery suspensions.

Q:How do these materials perform in different conditions?

A:The rubber lip provides good flexibility and sealing performance across temperatures from -30°C to +100°C, while the steel shell resists deformation under the heavy clamping forces of the suspension joint. It’s highly resistant to mineral greases and common contaminants, making it reliable in dusty, wet construction sites.

Q:How long does this equalizer bar seal typically last?

A:Under normal conditions with proper greasing and installation, it can last between 5,000 and 10,000 operating hours. In harsh environments with frequent water exposure or heavy loads, it may need replacement sooner, but with regular maintenance, it will keep the suspension running smoothly for years.
