linear motion actuators are available in six different sizes and multiple rail lengths. As well, four block configurations are available: single long, double long, single short and double short. All products are available in one of two accuracy grades:
High grade
Precision grade
While linear actuators are sufficient for most applications, precision-grade products deliver overall improvements in positioning repeatability, positioning accuracy, running parallelism and backlash, which are necessary for use in high-performance environments.
Other options available for linear actuators include:
Top cover or bellows for additional protection against dust
Mounting brackets for use with various electric motor types
Limit sensors, including slim-type/compact photomicro, close-contact-capable or proximity sensors
Positioning pin holes on the side block or subtable
