For more than 35 years, Del-Tron Precision has been manufacturing linear motion products which we divide into nine 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, PDFs in each of the paragraphs below, and from our downloadable catalog page. For additional questions, please contact us directly.
Solid models are also available for download on both our homepage by clicking the downloadable CAD link, or at the bottom of each product data page.

Slides (Ball and 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.

Crossed Roller Tables (Aluminum & Steel):

Del-Tron Precision's Aluminum and Steel Crossed Roller Tables are designed for linear motion applications which require both extreme accuracy and exceptional load carrying capacities (including weights in excess of 2600 lbs). Our aluminum crossed roller tables are also available with corrosion resistant stainless steel internal components for applications where corrosion is a concern.
Other specific industry terms include crossed roller bearings, and crossed roller tables, while more general terms include linear bearings, roller slides, linear motion slides, or simply linear slides.

DL Linear Actuators:

Del-Tron Precision's DL Linear Actuators were specifically designed as a space-saving, economical solution for applications requiring long-life, and fast, as well as simple setup. Our DL linear actuators house a lead screw or ball screw in a rigid aluminum box structure which utilizes a recirculating guide to provide precision linear motion. A motor adaptor and motor coupling are supplied for either stepper or servo motors with limit switches also available. Travels range from 25mm up to 410mm while providing a straight line accuracy in the 2 micron range. Our DL Linear
Actuators are also sometimes referred to in the industry as linear actuators, lead screw actuators, ball screw actuators, linear positioners, linear motion actuators, or more generically as linear bearings.

High Speed Belt Drive Actuators:

Del-Tron Precision's Belt Drive Actuators provide both high speed and extended travels. They are capable of traveling at speeds up to 5.1 meters per second (MPS) and travel lengths of up to 6 meters while both maintaining a repeatability of +/- 0.025 mm and linear accuracy of +/- 0.083 mm per meter. A wide selection of gear heads, motor mounts, limit switches and mounting hardware are available.
They are also sometimes referred to as belt drive actuators, belt drive systems, belt drives, or simply linear actuators.

Posi-Drives^®:

Del-Tron Precision's Posi-Drives^® were created to provide an economical solution to simplify the design of motion control systems in some of the more common applications. These ball and crossed roller stages easily install with standard fasteners and do not require aligning any components. They are fitted with a lead screw and anti backlash nut and are supplied with a motor adaptor and coupling. Available in X, XY, and XYZ mounting configurations, with optional limit switches and up to 12" of travel, these linear motion stages provide both accuracy and excellent positional repeatability.
Other industry terms include lead screw stages, lead screw actuators, linear actuators, linear positioning stages, and lead screw driven stages.

Crossed Roller Rail Sets:

Del-Tron Precision's Crossed Roller Rail Sets are extremely compact, precision rail sets that support heavy loads with both excellent repeatability, and extremely low friction. These linear motion bearings are sold in sets and consist of 4 V-grooved rails and 2 roller cages. Available options include both stainless steel and our anti creep models for high speed and vertical applications. With travels ranging from .4" to almost 12", and load capacities in excess of 2800 lbs, Del-Tron Precision offers a wide range of choices.
They may also be referred to as crossed roller bearings, crossed roller rails, and crossed roller slides, and more generically as linear motion slides..

Recirculating Slide Guides:

Del-Tron Precision's Recirculating Slide Guides provide linear motion solutions for applications involving long travels and designs where space constraints must be considered. These recirculating guides consist of a block and a guide rail, both having two R-shape raceway grooves that are machined and precision ground. The block consists of a main body with two raceways and a resin return cap to ensure smooth circulation of balls. These precision steel balls roll in their respective raceway groove with contact at four points between the block and the guide rail. These low friction, compact and light weight recirculating guides are capable of carrying loads in excess of 700 kg., and provide travels up to 880mm with custom rail lengths up to 2 meters available in some sizes. Stainless steel units are also available where corrosion resistance is a design concern.
Our Recirculating Slide guides are also commonly referred to as ball slide guides, slide guides, linear bearings, linear slides, and linear motion slides.

Air Actuators:

Del-Tron Precision's Air Actuators provide both extremely low friction and stiction characteristics by using a pair of Airpot cylinders. The movement of these pneumatically actuated crossed roller slide assemblies can be stopped with a light touch or a physical obstruction for applications where preventing damage to delicate and expensive equipment or parts is required.
Our air actuators may also be referred to, in more general terms, as linear actuators, linear motion slides, and linear bearings.
