Rubber Insert Suspension Units
Construction
Our high-density rubber insert technology (R-flex insert) comprises of a central shaft and a metal case, which may be galvanised upon request. Four pre-tensioned high density rubber inserts are then placed between the two and completely surround the central shaft. When the force of loading or tension is applied to the unit, the high density rubber compress and expands into the air within the casing and thus provide suspension. The rubber inserts are engineered to specific load deflection characteristics and provide a reliable and predictable suspension solution over a long service life. The high density rubber inserts are produced to precision specifications.
Variations
R-flex insert systems can be supplied with/without stub and hub (hub can be braked/unbraked using standard, auto-reverse, hydraulic or mechanical brakes)
Mounting Plates
Mounting plates, which match the baseplates of the units, are available separately and can be attached to the trailer chassis. These units can then be easily bolted to them giving fast installation.
