Product Selection Guide
For more than 40 years, Del-Tron Precision has been manufacturing linear motion products which we divide into eleven families including ball slides, crossed roller slides, micrometer positioning slides, lead screw actuators, and ball screw actuators. Each of our product lines were designed to address specific linear motion requirements such as precise positioning accuracy, miniature motion, extended travels, and high load carrying capabilities. This Product Selection Guide is intended both to assist our customers in choosing the right product for their specific application, and to offer a brief description of each of our product families. Detailed information about each product family and their options are available through our family pages in the horizontal navigation menu above, on the homepage image collage, in the links below, and from our downloadable catalog page.
For linear motion applications requiring special design, Del-tron Precision also offers custom solutions. From design to prototyping to full-service manufacturing, we can help you achieve the perfect custom linear motion solution for your specific needs. Some of our customizations include: special materials (such as stainless steel internals and ceramic ball bearings), custom hole placement for specific mounting requirements, reducing magnetism, corrosion resistance, etc. Even after 40 years, our goal is personalized attention and a level of responsiveness that's unparalleled in the industry. For additional information on creating the perfect custom linear motion solution for your specific needs, please see our Custom Linear Motion page.

Slides (Ball & Crossed Roller)
Del-Tron Precision groups our Ball Slides and Crossed Roller Slides into a single product family for several reasons. Each ball slide has a corresponding crossed roller slide that is dimensionally equivalent. This offers our customers the flexibility to increase or decrease accuracy and load carrying requirements without needing to change their designs. It's as easy as changing the part number. Both our Ball Slides and Crossed Roller Slides are designed with an aluminum carriage and base which utilize both hardened steel and stainless steel bearing components and ways. These lightweight linear motion slides are available with either inch or metric hole locations and can easily be modified to meet specific needs.
While Ball Slides can also be referred to as linear slides, linear motion slides, ball slide assemblies, linear bearings, and linear ball slides, Crossed Roller Slides may also be referred to as roller slides, crossed roller bearings, linear and crossed roller slides.
Micrometer Positioning Stages
Del-Tron Precision's Micrometer Positioning Stages are often referred to as positioning stages, linear positioners, XY stages, micrometer stages, and micrometer slides. What distinguishes this family from other linear motion products is the addition of a micrometer which enables the ability to position a load or device in precise increments. Our micrometer positioning stages offer travels ranges from .25" to 2.0". These linear motion devices are available in both inch and metric versions and are offered in X, XY, and XYZ configurations. Both linear ball slide and linear crossed roller slide technology are available based on application needs. While most Del-Tron models are available with optional locking micrometers, all are available with Deltron's Posi-Lock feature that enables the carriage of the positioning stage to be locked in place, securing the carriage of the linear motion slide.
