Original Nabtesco RV Reducer RV-E/RV-C/RV-N Series for Heavy-Duty Robotic Joints

Nabtesco is the undisputed global leader in precision cycloidal speed reducers, with over 10 million units shipped worldwide. The RV-E (Standard), RV-C (Hollow Shaft), and RV-N (Compact) series are the industry benchmarks for heavy-duty industrial robots, CNC machines, and medical positioning equipment. Featuring a unique two-stage reduction structure, these reducers offer exceptional impact resistance, high torsional rigidity, and extremely low lost motion, maintaining micrometer-level positioning accuracy even under extreme heavy-load conditions.

Product Highlights

Extreme Rigidity & Torsional Strength: The cycloidal design distributes force across multiple contact points, ensuring minimal deformation under high loads.
Ultra-Low Lost Motion: The entire series maintains lost motion within 1 arc-min, ensuring absolute precision and repeatable stopping positions.
Massive Load Capacity: Integrated large-diameter angular contact ball bearings support massive external moments and axial loads directly without additional support.
Superior Impact Resistance: Capable of handling instantaneous torque up to 5 times the rated value, ideal for emergency stops and high-inertia robotic movements.
Compact & Proven Durability: Backed by over 30 years of field performance, the compact design ensures a design life exceeding 10,000 hours.
Versatile Configurations: Available in various formats, including large hollow shafts for cable management and ultra-slim profiles for space-sensitive applications.

RV-40E	392	1,960	81/105/121	< 1 arc-min	170
RV-80E	784	3,920	81/105/121	< 1 arc-min	215
RV-160E	1,568	7,840	81/105/121/153	< 1 arc-min	240
RV-320E	3,136	15,680	81/118.5/153/192	< 1 arc-min	315

Application Fields

Heavy-Duty Industrial Robots: J1 (Base) and J2 (Lower Arm) joints for automotive assembly and palletizing robots.
Precision Positioners: High-capacity multi-axis rotary tables in automated welding lines.
CNC Machine Tools: B-axis and C-axis rotary heads for 4-axis and 5-axis machining centers.
Satellite Antenna Positioning: High-precision elevation and azimuth tracking systems.
Large Medical Imaging: Gantry rotation for CT scanners and positioning for proton therapy systems.

Frequently Asked Questions

Q: How do you guarantee the authenticity of Nabtesco reducers?

A: We source directly through authorized Nabtesco distributors. Each unit features a unique barcode and serial number for verification via the official website or local branches.

Q: What is the main difference between RV-E and RV-C series?

A: RV-E is a solid shaft unit, while RV-C features a large hollow shaft, allowing laser beams, cables, or air hoses to pass through the center for simplified design.

Q: Do these reducers require manual lubrication?

A: Most units are shipped without lubricant. We strongly recommend filling with the specified VIGO GREASE RE0 after installation as per the official manual.

Q: What are the installation requirements for precision?

A: Requirements are very high. Flatness and perpendicularity of the mounting surface directly affect service life. Detailed installation guides are provided.

Q: Can you provide matching motor flanges?

A: Yes, we offer customized motor flanges and input gears compatible with major brands like Fanuc, Yaskawa, Siemens, and more.

Q: What is the expected service life of an RV reducer?

A: Under standard rated conditions, the L10 design life is typically 6,000 to 10,000 hours. Proper lubrication can significantly extend this duration.
