Rosta motorbases have been proven to help reduce costs in heavy-duty belt transmissions.

Rosta’s oscillating mountings, self-adjusting suspensions, self-tensioning motorbases and shock-absorber mounts can offer many advantages to companies in the mineral processing sector. From noise absorption and shock load resistance to maintenance-free operation and easy installation, there are many reasons these units are quickly becoming a top choice for customers in this industry.

Oscillating mountings

Rosta offers oscillating mountings for screens, shakers and feeders. Its Type AB screen mounts, for example, offer high load capacities, a high degree of isolation, solid borne noise absorption, shock load resistance, a long life expectancy, and fully controlled startup and run-out behaviour. This series includes a range of models with different load capacities and heights.


Rosta’s Type MB automatic motorbases for belt drives of slurry pumps, fans, screens, centrifuges and crushers provide automatic slack compensation, transmission without belt slippage, absorption of torque peaks by startup, extended lifetime of belt sets, and maintenance-free operation. Rosta motorbases have also been proven to help reduce costs in heavy-duty belt transmissions.

Shock absorbers

Rosta’s Type ESL shock absorbers can be used on impact tables for transfer stations to help absorb the force of falling lumps, and prevent the belt and sub-structure from damages. These units are engineered to withstand high impact forces, and can offer protection to conveyor belts, resulting in less belt abrasion, reduced noise level and increased belt life.

Self-adjusting suspensions

Rosta’s Type SE tensioners for the suspension of conveyor belt scrapers are self-adjusting, and offer continuous pressure on the scraper blade, absorption of scraper vibrations, maintenance-free operation, and fast and easy installation.
