SMC MSQB50R Compact Rotary Table Cylinder 190 Degrees

The SMC MSQB50R Compact Rotary Table Cylinder is a rack-and-pinion rotary actuator in the MSQ series that delivers 0–190° of rotation in a compact 50-size package, enabling fast, repeatable indexing of fixtures or parts in automated lines. This dual-acting pneumatic unit is designed for material-transfer applications, where a compact footprint and precise angular positioning matter. A standout feature is the internal shock absorber option, seen on variants like MSQB50R-XN, which damps end-of-stroke impact to protect tooling and extend service life. The seven-size MSQ family—including 10, 20, 30, 50, 70, 100, and 200—shares the same 0–190° sweep, making MSQB50R suitable for tasks ranging from simple rotary indexing to multi-station transfer workflows. Some configurations also offer auto switch capability for position sensing and PLC integration, enabling straightforward feedback loops in automation. With its compact form factor, robust rack-and-pinion drive, and SMC reliability, the MSQB50R is commonly used for rotating jigs, workpieces, or transfer trays between stations in pick-and-place fixtures, assembly lines, and packaging equipment.
