The 68YH Heavy-Duty Roller Cam Hollow Rotary Table from Sango Automation is designed for automated equipment that demands stable indexing, high load capacity, and precise rotary positioning. It combines a roller cam transmission, crossed roller bearing, planetary gearbox, and servo motor drive in a single integrated unit delivering 5 arc sec repeatability, 20 arc sec indexing accuracy, and a minimum setting unit of 0.001.
Sango Automation is a China-based manufacturer with over 10 years of experience in rotary index tables, hollow rotary actuators, cam indexing drives, and precision gearboxes. We serve automation equipment builders and integrators worldwide, with products shipped to India, Europe, Southeast Asia, and North America.
Key Specifications
Product Features
1. Roller Cam Transmission for Heavy-Duty Indexing
The 68YH uses a roller cam mechanism to convert input rotation into controlled output movement. The profiled cam works with rollers to transfer motion to the rotary table, generating precise indexing positions. Compared with conventional gear transmission, roller cam contact provides smoother motion, reduced backlash, and longer service life under continuous operation.
2. Hollow Rotary Structure for Simplified Machine Integration
The hollow center allows cables, pneumatic lines, shafts, and other machine components to pass directly through the rotary axis. This simplifies fixture design, reduces external routing complexity, and makes the rotary table easier to integrate into automated equipment with components arranged around the center axis.
3. High-Precision Positioning
With 5 arc sec repeatability and 20 arc sec indexing accuracy, the 68YH delivers consistent positioning for automated indexing processes. Concentricity is within 0.01 mm, face runout is below 0.01 mm, and parallelism is below 0.02 mm supporting installation precision in demanding automation applications.
4. Servo Motor + Planetary Gearbox Drive
The 20:1 reduction ratio provides speed reduction between the servo motor and rotary mechanism. The servo motor supports programmable positioning, making the 68YH compatible with machine control systems for flexible indexing sequences.
5. Heavy-Duty Load Capacity
Combining the roller cam transmission with a crossed roller bearing, the 68YH supports higher load requirements: 150 kgf thrust load, 1580 N radial load, 2160 N axial load, and 55 Nm inertia torque. The crossed roller bearing supports the rotary structure in both radial and axial directions.
