Nabtesco offers a variety of gearhead types tailored to different applications, each designed to provide precise motion control. The main gearhead types include:
RD2 Series:
Description: Advanced precision reduction gearheads compatible with major servomotors, pre-filled with grease, and designed for easy installation.
Variants:
RDS-E: Solid shaft series.
RDR-E: Right-angle input type (solid shaft).
RDP-E: Pulley input type (solid shaft).
Features:
High precision with backlash less than 1 arc-minute.
Compact design with reduced total length.
Sealed and pre-lubricated for maintenance-free operation.
Applications: Suitable for various automation and robotics applications requiring precise positioning.
RH-N Series:
Description: High torque precision reduction gearheads based on the RV-N component sets.
Features:
Solid shaft design.

High allowable acceleration torque, up to 7, 000 Nm.
Applications: Ideal for machine tools, rotary tables, and handling applications where high torque and precision are essential.
RD-C Series:
Description: Gearheads featuring a large hollow shaft for feeding cables and supply lines.
Variants:
RDR-C: Right-angle input type (hollow shaft).
RDS-C: Straight input type (hollow shaft).
RDP-C: Pulley input type (hollow shaft).
Features:
Hollow shaft rotates at the output speed.
Completely sealed with integrated motor adapter plate and coupling.
Applications: Used in applications requiring a hollow shaft for cable routing, such as certain robotic and automation systems.
RA Series:
Description: Specialized gearheads designed primarily for machine tool applications.
Variants:
RA-A: Case rotating type, enabling precision indexing with case rotation.
RA-C: Shaft rotating type.
Features:
Compact design.
Backlash less than 1 arc-minute.
Integrated main bearing and motor coupling.
Applications: Commonly used in Automatic Tool Changers (ATC), magazines, arms, and turrets of machine tools.
Each gearhead type is designed to meet specific application requirements, offering varying features such as shaft design, torque capacity, and compatibility with different motor types. When selecting a gearhead, consider factors like the required torque, precision, installation space, and the nature of the application to ensure optimal performance.
