SMC Corporation MK2B25-20L Rotary Clamp Cylinder

SMC MK2TB25-20L Rotary Clamp Cylinder is a high-load rotary clamp actuator in SMC’s MK2 family, designed to provide reliable rotary clamping motion for workpieces in automated equipment. The model designation MK2TB25-20L reflects a 25 mm bore and a 20 mm stroke, consistent with SMC’s MK2TB-series naming. The TB designation places it in the MK2T line, described as a double-guide type rotary clamp cylinder, which gives increased rigidity during rotation. As part of the MK2 heavy-duty family, this cylinder is intended for demanding clamping tasks where repeated rotation and secure positioning are required in manufacturing environments. This combination of bore, stroke, and structural design makes MK2TB25-20L suitable for mid-range clamping and indexing steps in automated fixtures and transfer tooling, where consistent alignment and repeatable motion are essential.
