LINEAR MOTORS SECTION
ServoTube Linear Actuators
ServoTube linear incorporate a long-life lubrication-free bearing. Built-in position feedback delivers up to 12 micron repeatability. Indusry standard mounting simplifies installation. Actuators are IP67 rated and deliver continuous force from 7-276 N.
ServoTube Linear Motor Components
ServoTube linear motor components are designed to integrate into OEM machinery and require an external bearing. Loads can be mounted directly to the rugged forcer. Built-in position feedback with up to 12 micron repeatability simplifies installation. Motor components are IP67 rated and deliver continuous force from 7-276 N.
Linear Motor Modules
Linear motor modules are ready-to-use and equipped with bearing rail, limit switches and drag-chain. A linear encoder option is available for high precision applications. Consult Copley sales representative to specify a module for your application.
