RPU plastic unit by Rosta offers inherent damping, vibration isolation

Rosta's new series of RPU elements

Rosta Inc. is a premier Canadian manufacturer and supplier of machine elements and components, working off the groundbreaking success of its parent company in Switzerland. Offering solutions in three important areas – rubber-suspension, oscillating-conveyor, and tensioning technology – the company is always expanding its portfolio with fresh new innovations. One of the latest products available from the skilled producers at Rosta is the Rosta Plastic Unit, or RPU, which represents a whole new level of customization.

A completely bespoke torsion-spring-based solution

A precision machine component designed to meet the exact specifications of any user, the RPU is a completely bespoke torsion-spring-based solution – one that Rosta has engineered and developed by leveraging advances in material science, modern manufacturing techniques, and its own decades of expertise.

The RPU is a torsional spring with inherent damping, just like the standard Rosta element, with a versatile range of functions. This plastic unit can serve as a pivot bearing while offering vibration isolation, and it can exert or resist a force, absorb kinetic energy, and guide or control oscillating motion. With its decades of experience, the Rosta team is happy to work closely with customers to understand their specific needs for the performance of the component and co-develop the ideal solution. After initial prototyping, testing, and full client acceptance, Rosta will produce and supply the plastic unit according to the precise specifications.

RPU technology works in a unique way. A rigid material forms the inner and outer sections, while a second flexible polymer material offers connecting elasticity. The design, geometry, and choice of flexible polymer in the construction can determine the degree of relative movement of both the inner and outer sections. In addition, the user can precisely engineer the physical limits and performance, including the spring rate and the damping co-efficient.

Central to the company portfolio of specialized machine components designed to offers a blend of useful functions, the standard Rosta element is an elastomer-powered torsional spring that offers reliable performance across a wide variety of industrial applications. Sectors from agriculture to mining and transportation rely on Rosta.
