Electric actuator LA21

linearscrew spindle24-volt

Overview
The LA21 (LINAK) is a compact industrial electric linear actuator designed for fast, precise positioning where installation space is limited. Optional Integrated Controller (IC) versions and straight or angled cable options simplify installation and system integration.

Performance and durability
The LA21 delivers up to 3,500 N of push/pull force, speeds up to 85 mm/s and stroke lengths up to 800 mm. Engineered for harsh environments, it resists vibration, moisture, chemicals and extreme temperatures. The actuator features robust metal gears and an integrated brake. Protection rating is up to IP66 during operation and up to IP69K when idle; it tolerates high-pressure cleaning up to 90°C at 320 bar.

Key features

• Compact design: Three-part motor housing tightly encloses spindle and components to minimise space usage; straight or angled cable options for confined installations.
• Performance range: Available in load categories from 500 N to 3,500 N; speeds up to 85 mm/s for fast, precise movement.
• Environmental resistance: Dust/water protection and suitability for high-pressure cleaning; rated IP66 (operation) and IP69K (idle).
• Flexible configurations: Stroke lengths from 50 mm (70 mm for IC versions) up to 800 mm and multiple mounting options.
• Multiple voltages: Operates on 12 V, 24 V or 48 V to match system architectures.
• Integrated intelligence: IC versions provide on-board control, positioning feedback and bus interfaces for advanced integration.

Applications
Used across sectors where space is limited but power, reliability and speed are required: agricultural machinery, construction equipment, vehicles, industrial automation and mobile robotics.
