<h2>Overview</h2>
<p>The <strong>PHD SDB25X4-1/2-AE-DB-E-H4</strong> is a pneumatic linear slide from PHD’s versatile SDB series. This double-acting thruster slide is designed for precision positioning and material handling in compressed air systems. The unit combines a 25mm bore cylinder with a 4-1/2-inch stroke to deliver consistent linear motion across automation, assembly, and material transfer applications.</p>
<h2>Key Features</h2>
