( Brand: Bimba ), ( Manufacturer Part Number: SR091D ), ( Part Type: Pneumatic Cylinder )
The **Bimba SR091D (SR-091-D) Pneumatic Cylinder** is a high-performance, compact, and versatile linear actuator designed to deliver precise, reliable motion control in a wide range of industrial and automation applications. Part of Bimba s renowned **SR Series**, this rodless pneumatic cylinder combines advanced engineering with robust construction to provide smooth, repeatable linear movement with minimal friction and wear. Engineered for efficiency, the SR091D features a **double-acting design**, allowing for bidirectional motion with equal force in both extension and retraction cycles, making it ideal for applications requiring symmetrical operation such as indexing, clamping, positioning, or material handling. Its **aluminum-alloy housing** ensures lightweight yet durable construction, reducing overall system weight while maintaining structural integrity under high-pressure conditions, typically rated for **80 100 psi** (5.5 6.9 bar) of operating pressure. The cylinder s **sealed rodless design** eliminates the need for external rods or guides, minimizing wear and tear while maximizing space efficiency, particularly in tight or confined environments where traditional rod-end cylinders would be impractical.
One of the standout features of the SR091D is its **integrated magnetic feedback system**, which provides precise position sensing without the need for external limit switches or encoders. This built-in **magnetostrictive position feedback** allows for accurate, real-time monitoring of the cylinder s position, enabling closed-loop control for enhanced accuracy in applications such as robotic assembly, packaging, or automated testing. The feedback system is seamlessly compatible with most industrial control systems, including PLCs and motion controllers, facilitating seamless integration into larger automation workflows. Additionally, the cylinder s **low-friction design**, achieved through high-quality seals and a smooth bore, ensures minimal energy loss and extended operational life, reducing maintenance requirements and downtime. The **quick-connect fittings** on both ends of the cylinder further simplify installation and maintenance, allowing for rapid disassembly and replacement of components when necessary.
The SR091D is also engineered for **high-speed operation**, with a stroke length of **91 mm (3.58 inches)** and a compact overall length that makes it suitable for applications where space is at a premium. Its **standard bore sizes** (typically ranging from **12 mm to 25 mm**) accommodate a variety of force requirements, with the ability to generate **thrust forces up to 1,200 N (270 lbs)** depending on the specific configuration, making it adaptable for light-duty to moderate-load applications. The cylinder s **sealed, dust-tight construction** ensures protection against contaminants, making it well-suited for cleanroom environments or applications where hygiene is critical. Furthermore, Bimba s commitment to quality assurance is evident in the SR091D s **rigorous testing standards**, including pressure, leak, and endurance testing to ensure consistent performance under demanding conditions.
Beyond its technical specifications, the SR091D is designed with **user convenience in mind**, featuring a **modular mounting system** that allows for flexible installation in various orientations, including horizontal, vertical, or even angled applications. The cylinder s **low-profile design** and absence of protruding rods make it ideal for applications where clearance is limited, such as in automated conveyors, sorting systems, or medical equipment. Whether used in **automotive assembly, food and beverage processing, pharmaceutical manufacturing, or general industrial automation**, the SR091D delivers a reliable, cost-effective solution for precise linear motion. With its combination of **compact size, high efficiency, and advanced feedback capabilities**, this pneumatic cylinder stands out as a versatile workhorse in modern automation, offering engineers and technicians a dependable choice for a wide array of motion control challenges.
