SMC MSQB20R Pneumatic Rotary Table Actuator Rack and Pinion 0.6 MPa

SMC MSQB20R Pneumatic Rotary Table Actuator Rack and Pinion 0.6 MPa

The SMC MSQB20R is a compact rack-and-pinion pneumatic rotary table from SMC Corporation's MSQ series. It converts linear pneumatic motion into precise rotary output through an internal rack-and-pinion mechanism, providing repeatable angular positioning for automated assembly, pick-and-place, and indexing applications. The rotating table face features a bolt-circle mounting pattern for direct fixture or tooling attachment.

Applications

The SMC MSQ series rack-and-pinion rotary actuators are widely used in industrial automation for tasks that require precise angular rotation — typically 90°, 180°, or user-defined angles via the adjustable stops. Common applications include pick-and-place end-of-arm tooling on robotic systems, part-transfer and reorientation fixtures, semiconductor wafer handling stages, and automated assembly lines where a workpiece must be rotated and held at a defined angle. The compact rectangular body and flat rotary table make these units easy to integrate directly into custom fixturing and multi-axis motion stages. SMC is one of the world's largest pneumatic component manufacturers, and the MSQB series has been a standard in factory automation since the 1990s, with broad compatibility across SMC's push-in fittings, speed controllers, and auto-switch sensor families.
