ZCTZ-280 Heavy-Duty Hollow Rotary Table
The ZCTZ-280 heavy-duty hollow rotary table is designed for servo-driven rotary systems requiring higher load capacity, stronger moment support, and a larger hollow output platform. Compared with smaller frame rotary tables, ZCTZ-280 is better suited for heavy fixtures, CNC auxiliary rotary axes, automated indexing stations, and industrial positioning equipment requiring stable operation under larger loads.
Key Features of ZCTZ-280
Heavy Load Platform
Designed for larger fixtures, stronger axial load requirements, and demanding industrial rotary positioning applications.
Large Hollow Center
The hollow output structure allows cable, air pipe, and fixture routing through the center for cleaner equipment integration.
Strong Moment Support
Higher allowable moment of inertia and overturning moment help support stable indexing under heavier fixture conditions.
Servo Motor Matching
Compatible with 1000–3000W servo motor applications for high-load automation and CNC rotary positioning systems.
Ordering Code Example
Example ordering code: ZCTZ-280-50-24-110-145-M8. Move your mouse over each code segment to understand the meaning. Final motor interface dimensions should be confirmed according to the selected servo motor and installation requirements.
Frame Size
ZCTZ-280 is selected when the application needs a larger platform, stronger load support, and more stable heavy-duty positioning.
Ratio Selection
L1 ratios are suitable for faster indexing. L2 ratios help increase output torque for heavier rotary motion requirements.
Motor Interface
Motor shaft diameter, pilot diameter, hole pitch, and screw size should match the actual servo motor drawing.
Selection Note
Confirm load weight, fixture diameter, inertia, rotation speed, ratio, motor power, and installation direction before ordering.
