Series MSUB: High-Precision Rotary Table

Compact Vane-Type Rotary Actuator for Industrial Automation

The Series MSUB is a high-precision rotary table designed for compact automation applications requiring accurate angular positioning and robust load-bearing capabilities. Utilizing a vane-type design, it offers a lightweight and space-saving “free-mount” configuration, allowing for flexible installation in various orientations.

High-Precision Angle Adjustment

The Series MSUB features integrated adjustment bolts that allow for precise tuning of the rotation range at both ends of the stroke.

Single Vane Type: Offers a total adjustment range of ±10° (±5° at each end of the rotation).
Double Vane Type: Offers a total adjustment range of ±5° (±2.5° at each end of the rotation).
Adjustment Range Examples: For a 90° model, the single vane type is adjustable from 80° to 100°, while the double vane type is adjustable from 85° to 95°.

Allowable Load Capacities

To ensure service life and prevent loss of accuracy, the load applied to the table must remain within the following parameters:

Size	Allowable Radial Load (N)	Allowable Thrust Load (N)	Allowable Moment (N·m)
MSUB1	20	15 (Directional)	0.3
MSUB3	40	30 (Directional)	0.7
MSUB7	50	60 (Directional)	0.9
MSUB20	60	80 (Directional)	2.9

Key Performance Features

Auto Switch Integration: Compatible with both Reed (e.g., D-90, D-R73) and Solid State (e.g., D-S99, D-T79) auto switches for precise end-of-stroke detection.
Flexible Porting: Available with either Side Ports or Top Ports (SE type) to accommodate tight installation spaces.
Free-Mount Capability: The actuator body features a “Free-mount” design with multiple mounting holes and a positioning pin hole on the table surface for rapid, accurate alignment.
Maintenance: Gripper and rotary sections are modular, allowing for easier maintenance and component replacement
