TROY, Mich. — ArvinMeritor has launched the new Meritor SimilAir Composite Trailer Spring for linehaul and general service applications. Officials say the SimilAir delivers ride quality close to that of an air suspension with much lower initial and life cycle costs.
“Meritor’s SimilAir is breakthrough technology that delivers the smooth ride operators expect from an air suspension without the added maintenance, weight and cost,” said Robert Zirlin, director of product planning and development for North American trailer products. “What sets this spring apart from other mechanical systems is its composite material, which offers numerous performance and bottom-line advantages to fleets and end-users.”
ArvinMeritor says the composite spring assembly is more durable and provides a significant weight and cost savings. The company also boasts that suspensions equipped with the new composite spring weigh as much as 240 lbs. less than the lightest air suspensions, and over 100 lbs. less than popular mechanical suspensions. The company says it also offers less maintenance than air suspensions, and is more corrosion-resistant than steel springs.
ArivinMeritor says the SimilAir has many distinctive advantages over its competition including:
– No air springs, shock absorbers or leveling valves (vs. air) – Drive-home capability greatly reduces potential for costly roadside maintenance – Mechanical suspension performance at the dock (i.e. no dock walk) – Significantly reduces unwanted vibration and noise compared to steel springs
