Linear Modules and Linear Translation Stages

What Are Rodless Actuators / Linear Modules?

Linear modules and linear tables are rodless actuators that typically use one or two guiding rails to guide a moving table or platform. In contrast to rod-type actuators, a linear module can usually handle lateral forces and provides defined straightness and flatness motion performance parameters.

They are used in automation, precision assembly, optics, metrology, semiconductor tools, test systems, and multi-axis positioning systems where a guided moving platform is more useful than a simple extending rod.

Product Examples

Linear Slide / Linear Module with Direct Drive Linear Motor

• High speed up to 5 m/sec
• Direct-drive linear motor for fast acceleration and maintenance-free operation
• Up to 1200 mm travel range
• 0.5 µm repeatability for accurate motion control in automation applications
• Absolute measuring linear encoder available

This linear slide module is designed for high-performance automation applications and provides maintenance-free motion with speed up to 5 m/sec and load capacity up to 1000 N. A direct-drive linear motor provides acceleration to 5 g and long service life due to its frictionless, wear-free design.
