CRV-H (Hollow Shaft)

CRV-H high precision reduction gears with through-holes in the shafts, also known as the hollow-shaft version. Cables, tubes with compressed air, drive shafts and so on can be led through the hole in the shaft of the gear.

This series high precision reduction gears comprise an accurate reduction mechanism and high-capacity radial and axial cylindrical bearings. This design of the reduction gears allows the mounting of the load directly on the output flange or case without a need of additional bearings.

Advantages

Hollow shaft construction
Backlash less than 1 arc.min
Lost motion less than 1 arc.min. Internal main bearing
Fully sealed
High moment capacity
High efficiency
Long lifetime
High torsional and tilting stiffness
