Gearhead is a sealed and pre-lubricated precision gearbox, complete with accomodations for motor mounting ( major motor manufacturers). Three input types are available.

RDS SERIES

Advanced precision reduction gearhead model

Basic Info

RDS-E (Solid)

RDS-C (Hollow Shaft)

Basic Info

The precision reduction gearhead model RD Series has been re-launched as the RD2 series. Featuring the same easy to use design utilizing fittings compatible with all major servomotors and sealed with grease before shipping, the new series has also reduced the total length by up to 15%.

Backlash less than 1 arc. min.
Lost motion less than 1 arc. min
Internal main bearing.
Major motor coupling parts included
Sealed grease

RDR SERIES

Right angle input type precision reduction gearhead model

Basic Info

RDR-E (Solid)

RDR-C (Hollow Shaft)

Basic Info

The RD2 series introduces the right angle type as a new input option. The right angle input allows for the creation of lower profile designs to be set up in smaller spaces. Especially useful for turn table applications, the right angle input type maintains high accuracy positioning while allowing for space saving, low profile designs
