Mayr Power Transmissions has unveiled the Robaa-topstopa, a fully sealed drive-side-mounted safety brake suitable for any vertical- or gravity-loaded axis.

Designed to meet the demands of EN ISO13849-1, the compact and lightweight Robaa-topstopa can be retrofitted to existing servo systems to prevent uncontrolled vertical movements in a power-off or emergency-stop situation.

The Robaa-topstopa is available as a single- or double-circuit brake with either a shaft output to connect to a gearbox or an integrated plug-in coupling to enable connection directly to a ballscrew.

Available in three standard sizes ranging from 12Nm to 170Nm, the Robaa-topstopa is said to offer safe and reliable braking even with the motor removed.

With a housing sealed to IP54 and flanges that can be adapted to any application, the Robaa-topstopa provides a simple, safe and economical vertical-axis braking solution, according to the company.
