SMC MKB40-10LZ Cylinder

SMC MKB40-10LZ is a 40 mm bore rotary clamp cylinder from the MK‑Z series, delivering a 10 mm clamp stroke with counterclockwise (left) rotation to achieve a 90° clamping action. It uses standard through‑hole mounting with a standard body and female port threads sized for 1/8" BSPT, and it can accommodate auto switches on multiple surfaces; the MKB40-10LZ‑M9BW variant includes two auto switches (M9BW) with a 0.5 m lead wired for DC24 V operation. The cylinder operates between +0.1 and +1 MPa (approximately 1–10 bar) with a proof pressure of +1.5 MPa, and provides a clamp force of 525 N at 0.5 MPa. Its overall length is about 139.5 mm, with a 57 mm width and 57 mm height, and it weighs roughly 1.14 lb. The unit is rated for −10 to +60 °C and originates in Japan, making it compatible with SMC MK mounting standards for precise fixture clamping, including a 90° arm opening and rubber bumper cushioning to absorb impact.
