New Original FESTO 535463 CLR‑50‑50‑L‑P‑A Pneumatic Clamping Cylinder

Product Overview

The FESTO CLR‑50‑50‑L‑P‑A (part number 535463) is a rotary‑clamping pneumatic cylinder designed and manufactured by FESTO, a global supplier of pneumatic and automation components. This unit combines rotary motion and linear pressing movement in one compact housing. It is widely deployed in automated assembly lines, fixture clamping stations, material handling workcells, and machine‑tool auxiliary clamping systems. When supplied with compressed air, the cylinder first rotates its piston rod to a preset angle, then delivers linear clamping force to lock workpieces securely. The “New Original” designation indicates genuine factory‑new product, with complete factory testing, original mechanical seals and internal components, free of refurbishment or second‑hand modification. This clamping cylinder is built for continuous‑cycle industrial operation under standard workshop compressed‑air supply conditions.

Main Functions

1. Combined rotary‑linear clamping motion: The piston rod executes a rotational stroke first, followed by a linear clamping stroke to reach the working position for workpiece holding.
2. Workpiece holding and fixture locking: Provides stable mechanical clamping force to fix workpieces during machining, assembling or testing procedures.
3. Pneumatic double‑action operation: Compressed‑air signals control both the clamp‑down action and the release‑return action without mechanical spring reset for main movement.
4. Position‑dependent force output: Generates rated clamping force upon completion of both rotary travel and linear travel.
5. Compatibility with external position sensors: Supports mounting of FESTO proximity sensors for feedback of cylinder end‑position status for host‑system logic control.
6. Anti‑misoperation mechanical structure: Internal mechanical limit structures prevent over‑rotation and over‑travel to protect internal parts against improper air‑supply pressure.

Technical Characteristics

• Integrated rotary‑linear structure merges two‑phase movement within single cylinder body, saving installation space compared with separate rotary actuator plus linear cylinder combinations.
• Hard‑anodized aluminium alloy cylinder barrel for high wear‑resistance and corrosion resistance in ordinary industrial environments.
• Precision‑ground piston rod with low‑friction sealing assemblies to extend service life for millions of working cycles.
• Double‑action pneumatic driving mode; movement fully driven by compressed air without main return spring.
• Standard interface for proximity sensor installation to realize electrical position feedback for automation control loops.
• Built‑in mechanical end stops for rotary angle and linear stroke to guarantee repeatable positioning accuracy.
• Suitable for filtered compressed‑air media; operating environment adapts to general factory‑floor temperature ranges.
• Modular mounting interfaces simplify installation onto fixture bases and machine work‑tables.
