SMC MHW2-20D1 Pneumatic Two-Finger Angular Rack Pinion Gripper

The SMC MHW2-20D1 is a compact two-finger angular rack-and-pinion air gripper with a 20 mm bore and a 180° opening, designed for synchronized finger motion in tight spaces. Each finger is driven by a rack-and-pinion mechanism that translates pneumatic motion into coordinated angular rotation, producing a stable pinch across a full 180° sweep. The gripper provides about 0.30 N·m of gripping torque and operates on compressed air within a 22–102 psi range, with an ambient temperature tolerance of 14°F to 140°F, making it suitable for small-part handling across varied environments. As a right-angle, tapped-mount variant within the MHW2 family, this model is intended for installations needing perpendicular grasping and flexible mounting in-line or above conveyors, with two-finger geometry that supports reliable engagements on small cylindrical or flat parts. This configuration is a double-acting actuator-based gripper, designed to be used in automation tasks such as assembly, packaging, and fixture loading where precise, repeatable finger motion is required.
