Features [Strong and durable] Hard oxidation technology is applied to the surface of the cylinder, increasing surface hardness, reducing deformation, and enhancing durability. [Automatically increase sealing performance] As pressure increases, this 20mm bore pneumatic cylinder automatically improves sealing performance for longer service life. [Exquisite workmanship] The cylinder body is precision-formed in one piece with accurate hole spacing and strong sealing capability. [Good stability] The parallel-style air gripper pneumatic cylinder uses high-precision steel ball slide rails with zero clearance, ensuring smooth operation and preventing ball detachment. [High-quality material] The MHZ2-20D air gripper pneumatic cylinder is constructed from high-quality aluminum alloy, offering strength, corrosion resistance, and rust prevention.
