Our semi bonded rubber suspension unit technology (R-flex semibond) gives the benefits of bonded suspension technology whilst remaining excellent value for money. R-flex semibond technology offers a greater service life than rubber inserts (R-flex insert) because the shaft is fully encased in rubber. Being fully encased, the R-flex semibond unit also offers better water and dirt protection, than the R-flex insert units.

Construction

R-flex semibond technology comprises of a central shaft surrounded by a metal case (which may be galvanised upon request). High density rubber is then bonded to the central shaft and completely fills the space between the metal casing and shaft itself. The unit also includes a support brush at the drop arm end which is inserted into the end of the casing and helps to maintain the position of the shaft and wheel alignment. The rubber filling is engineered to specific load deflection characteristics requested by customers and provide a reliable and predictable suspension solution over a long service life. They provide greater predictability and are capable of dealing with heavier duty uses than our R-flex insert units, yet provide a more affordable solution than our fully bonded units (R-flex fullbond).

Splining

R-flex semibond central shafts and arms can, upon request, all be splined, allowing the level of the arms to be altered for different ride heights whilst providing incredibly strong connections with mounting plates. It also means arms can be replaced without changing the whole unit, further reducing operational costs.

Variations

R-flex semibond systems can be supplied with/without stub and hub (hub can be braked/unbraked using standard, auto-reverse, hydraulic or mechanical brakes)
