Special features:
• twin-bearing actuating rod, more convenient for heavy load application range from 50-900mm.
• mountable via backlash-free pivot heads with a large angle of free movement (up ±12.5°).
• outstanding linearity ±0.05％.
• resolution better than 0.01 mm.
• long life up to 10 million movements, depending on application.
