R Series Inline Helical Geared Motor

MANUFACTURER DOCUMENTATION

Overview

Tunsing’s R series uses helical gearing in an inline gearmotor arrangement. Its company-hosted illustrated catalog lists foot and flange mounting, solid-shaft output and combinatorial drive variants. On the official R-series selection table, the R37 column shows an input-power range of 0.18 to 3 kW and 200 Nm permissible torque. The page also diagrams mounting positions M1 through M6 and terminal-box rotations of 0, 90, 180 and 270 degrees. These are configuration options, not performance guarantees for every motor choice. For a comparison, specify the intended R frame, ratio, input motor, output shaft and service load, then confirm the exact table cell and drawing with the maker.

Before you specify this gearbox

Helical gearboxes are used in a broad range of industrial drives. Mounting position, service factor, thermal capacity and lubrication are part of selection, not just the nameplate power.

• Confirm continuous, peak and emergency-stop load limits separately.
• Match the motor flange, shaft, mounting orientation and lubrication requirements.
• Request the current drawing revision and selection calculation from the manufacturer.
