ROSTA
Oscillating Conveyor Technology
Our core business, the elastic, neutral reaction and almost vibration-free suspension of oscillating machines and screens in the processing industry.
For all freely vibrating systems, from onion sorting shakers in the tinned food industry up to the ore dewatering screens in mines, ROSTA offers standardised suspension variants with the highest levels of isolation.
The support of gyratory screening machines is our speciality; we supply vibration-damping universal joint suspensions for load supports from 200 to 40’000 N.
For fast, wear-free shaker conveyors with crank drives, ROSTA has a wide range of standard rocker arms for the careful suspension of conveyor and screen troughs — and even for systems with natural frequency operation!
Tensioning Technology
The concept and production of machine components for the maintenance-free tensioning of belts and chain drives has always been a core competence of ROSTA.
Whether for the initial tensioning of large belt drives with our self-adjusting motor base suspensions or for efficient secondary tensioning by means of easy-to-install chain and belt tensioners, ROSTA has the standardised solution!
When using the ROSTA tensioning systems, problems such as the compensation of lengthening due to age and belt slip are no longer an issue in your machine design — you can simply forget the periodical re-tensioning maintenance! The ROSTA tensioners should be installed on a stiff, even and clean machine part by means of the central bolt. The frictional connection on flange is usually fully sufficient for final positioning. The positioning notch on flange can be used to assure the tensioner additionally on uneven and dirty surfaces by setting a roller-pin.
Rubber Suspension Technology
You need a suspension system that does not even exist yet! We will be very happy to manufacture it for you.
ROSTA currently manufactures 2,374 customer-specific special Rubber Suspension units! From the smallest production runs in welded construction up to large volumes for the automotive industry, in sintered metal construction or precision moulding.
For the construction of special machines, in which the requirements on the suspension system that change almost daily, 124 standard modules are available with assembly clamps for individual solutions.
The damping of vibrations is also a strength of the ROSTA Rubber Suspension units. A wide range of highly efficient anti-vibration mounts guaranteed against tearing are included in our standard program.
