A space-saving linear actuator with precision-machined square profile, featuring integrated mounting grooves for tool-less sensor installation. The PTBR series' pen-type design minimizes deflection during operation through optimized guide geometry. Includes wear-resistant rod bushing and anti-rotation mechanism for stable reciprocation. Requires 5μm filtered dry air (lubricated or non-lubricated).
- Precision clamping in SMT pick-and-place machines
- Valve actuation in medical analyzers
- Component ejection in micro-molding systems
- Optics alignment mechanisms
- Laboratory automation positioning
Installation note:
For vertical mounting, reduce max payload by 30%. Use 2Nm torque for mounting screws.
Apply 2-3 drops of ISO VG32 oil monthly if using non-lubricated air supply.
