For simple flange mounting to special drive components, Custom flange patterns available

Easy to mount, optional: bolt tensioning system in size 800 and up, light weight and low moment of inertia

High clamping pressure, high torque version, compact design

Easy installation and removal, electrically and thermally isolating, absolutely backlash free and torsionally stiff

Axial mounting possible, easy installation and removal, electrically and thermally insulating, absolutely backlash free and torsionally stiff

For hollow shaft mounting, short design saves installation space, easy to mount

ROSTA oscillating mountings ensure smooth, controlled vibration for screening, conveying, and processing applications — providing high efficiency, long service life, and maintenance-free operation.

ROSTA motor bases ensure rigid and geometrically stable installation of the electric motor, allow precise adjustment of the center distance and belt tension, reduce starting loads, and increase the service life of the drive.

Easy mounting, high concentricity, vibration damping

Short overall length, easy mounting, vibration damping

Lateral mounting, easy installation and removal, high concentricity

High lateral misalignment, easy to mount, combine with any two hub design

High clamping pressure, very high concentricity, axial mountable

For hollow shaft mounting, short overall length, saves mounting space and costs

Low-priced, high concentricity, low backlash (keyway)

ROSTA – automatic belt and chain tensioners ensuring consistent performance, extended service life, and reduced maintenance.

The reliability and innovations of TWIFLEX in braking systems is an engineering solution that will address the most ambitious tasks for high-tech drive units and assemblies.
